Does CPR apply to every cable placed on the EU market?

No. The Construction Products Regulation only applies to construction products covered by a harmonised European standard (hEN) cited in the Official Journal of the European Union, or by a European Assessment Document (EAD) leading to a European Technical Assessment (ETA). For cables, the relevant hEN is EN 50575:2014+A1:2016, which addresses power, control and communication cables intended for permanent installation in construction works subject to reaction-to-fire requirements. Patch cords, machine cables, flexible appliance cords, drag chains and other cables that are not permanently installed in a building generally fall outside the scope of EN 50575 and outside CPR; they remain under the Low Voltage Directive 2014/35/EU and the EMC Directive 2014/30/EU where applicable.

What is the difference between CPR (EU) 305/2011 and CPR 2.0 (Regulation (EU) 2024/3110)?

Regulation (EU) 305/2011, in force since July 2013, replaced the Construction Products Directive 89/106/EEC. It sets the rules for CE marking of construction products based on harmonised standards and Declarations of Performance. Regulation (EU) 2024/3110, published in December 2024 in the Official Journal, is the recast known as CPR 2.0. It updates definitions, introduces digital DoP and product passport provisions, broadens environmental and sustainability requirements, reinforces market surveillance, and clarifies the role of notified bodies. Most provisions apply from January 2026 with transition arrangements that extend several years for existing harmonised standards. During the transition, EN 50575:2014+A1:2016 continues to apply for cables already in scope.

Which AVCP system applies to cables under EN 50575?

EN 50575 maps cables to two AVCP (Assessment and Verification of Constancy of Performance) systems depending on the declared Euroclass. Cables declared Aca, B1ca or B2ca fall under system 1+, which requires a notified product certification body to perform initial type testing, audit the factory production control, and carry out continuous surveillance with periodic re-sampling. Cables declared Cca, Dca or Eca fall under system 3, which requires a notified test laboratory for initial type testing but leaves factory production control and ongoing surveillance to the manufacturer. Cables declared Fca (no performance determined) fall under system 4, which is full self-declaration without any notified body involvement.

Is LSZH the same as a CPR Euroclass?

No. LSZH (Low Smoke Zero Halogen) is an industry marketing label, derived historically from the smoke density requirements of IEC 61034-2 and the halogen acid gas requirements of IEC 60754-1/-2. It is not a Euroclass and has no formal definition under EN 50575 or under CPR. A cable can be advertised as LSZH and still hold any Euroclass from Aca to Fca, because the Euroclass is determined by a specific test battery (EN 50399, EN 60332-1-2) that LSZH alone does not address. Specifying LSZH in a tender does not satisfy the legal reaction-to-fire requirement set by Member State building regulations, which are written in terms of Euroclasses.

Does the CE mark on a cable replace LVD compliance?

The CE mark affixed under CPR refers exclusively to the reaction-to-fire performance declared in the DoP under EN 50575. It does not cover electrical safety, mechanical robustness, marking of conductor colours, or EMC. Cables that fall within the scope of the Low Voltage Directive 2014/35/EU (typically flexible cables and cords for direct connection to appliances) remain subject to LVD and to their own product standards (EN 50525 family for low-voltage cables, for instance). For fixed building-installation cables under CPR, LVD generally does not apply to the cable itself but does apply to the end equipment and to the installation as governed by HD 60364 (the European harmonised installation rules).

How is the Declaration of Performance organised under CPR?

The DoP is the mandatory document that accompanies every construction product placed on the EU market and that carries the CE mark. Its content is fixed by Annex III of Regulation (EU) 305/2011: unique identification code of the product type, intended use, declared performance for each essential characteristic listed in the harmonised standard, references to the hEN and the AVCP system, manufacturer details, and the signature of the responsible person. For cables under EN 50575, the declared performance is the Euroclass with the smoke (s), droplet (d) and acidity (a) sub-ratings. The DoP may be delivered on paper or, since CPR 2.0, in a digital form accessible through a QR code or a URL printed on the product or accompanying documentation.

Can a single cable type cover several Euroclasses?

No. The Euroclass is bound to a specific cable construction (conductor geometry, insulation compound, sheath compound, filler, armour where present). Any change to the construction that alters the reaction-to-fire behaviour invalidates the original classification and triggers a fresh initial type test. A common pitfall is to respool a base cable under a different brand or to substitute the sheath compound with a nominally equivalent grade: under CPR, both operations create a new product type that must be re-tested before the new DoP and CE mark can be issued. Production-control records must trace each compound batch to the tested formulation.

How do Member States set the minimum Euroclass for a building?

CPR harmonises the test method and the classification but not the level of performance required. Each Member State sets the minimum Euroclass through its own building regulations, fire safety codes and decrees, generally indexed on building use (residential, commercial, healthcare, schools, high-rise) and on the location of the cable inside the building (escape routes, riser shafts, technical floors). Germany typically requires Cca-s1,d1,a1 for escape routes in high-rise buildings; France references Euroclasses in the safety regulations for Establishments Receiving the Public (ERP) and in NF C 15-100; Italy implemented mandatory Euroclass use from July 2017. The product DoP must declare a Euroclass at least equal to the level required by the destination Member State.

CPR (305/2011) and EN 50575 cable reaction-to-fire

Author Hugues Orgitello Last updated 27 May 2026 ~17 min read

Guide. Construction Products Regulation and cable reaction-to-fire

The Construction Products Regulation (EU) 305/2011 (CPR) governs how construction products, including cables intended for permanent installation in buildings, are placed on the EU market. It replaces the 1989 Construction Products Directive with a regulation directly applicable in every Member State, harmonises the wording of CE marking through a Declaration of Performance, and requires manufacturers to assess and verify the constancy of declared performance against a harmonised European standard. For electronics designers and integrators whose products embed power and data cables fixed into building infrastructure, the harmonised standard is EN 50575:2014+A1:2016, which classifies cables by Euroclass on the basis of reaction-to-fire tests. This page describes the CPR route, the AVCP systems, the structure of the Declaration of Performance, the EN 50575 Euroclass system and the smoke, droplet and acidity sub-ratings, the test methods that feed into the classification, the impact of the December 2024 CPR 2.0 recast, and the recurring pitfalls observed when a cable goes through the certification chain.

Scope of CPR and place of EN 50575

CPR applies to construction products, defined as any product or kit produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof. A cable feeding a wall socket, a building automation bus, a fire alarm loop, a structured-cabling backbone or a photovoltaic array on a roof is a construction product when it is permanently installed in the building. A patch cord, an appliance cord, a portable extension lead, a machine-internal harness or a robot drag chain is not permanently installed and falls outside CPR; those products remain under the Low Voltage Directive 2014/35/EU, the EMC Directive 2014/30/EU and their own cable standards (EN 50525 for low-voltage cables in particular).

A construction product carries the CE mark under CPR only if it is covered by a harmonised European standard (hEN) whose reference is published in the Official Journal of the European Union (OJEU) or, in the absence of a hEN, by a European Assessment Document leading to a European Technical Assessment (ETA). For cables, the only hEN currently in scope is EN 50575 (2014, amendment A1:2016), titled Power, control and communication cables, cables for general applications in construction works subject to reaction-to-fire requirements. Optical fibre cables for permanent installation are included; coaxial and balanced cables for telecommunication are included; control and signal cables for building automation are included.

Other harmonised standards under CPR relevant to electronics integrators cover construction products that often embed electrical components: junction boxes and enclosures for fixed installation (EN 60670 family, where parts that act as construction products may also be hENs), photovoltaic modules in the context of building-integrated photovoltaics (EN 50583 BIPV), and conduit and trunking systems (EN 61386 family for protective systems, with overlap on building integration). For each of these, the cable-side reaction-to-fire performance still flows back through EN 50575 when wiring is permanently embedded.

Family	Likely hEN	CE marking route
Power and signal cables (permanent installation)	EN 50575	CPR DoP + CE mark on the cable
Junction boxes embedded in walls	EN 60670 family (building parts where listed)	CPR DoP where the part is on the OJEU list, otherwise LVD CE only
Conduit and trunking systems	EN 61386, EN 50085 (building parts)	CPR DoP where listed, otherwise LVD CE only
Building-integrated photovoltaic modules	EN 50583 BIPV	CPR DoP plus product-safety route under IEC 61730
Smoke detectors and fire alarm products	EN 54 family	CPR DoP, mandatory CE under CPR

A cable manufacturer that supplies a wiring harness embedded in a wall plenum operates in the CPR regime, including the obligation to deliver a DoP. An integrator who buys CPR-compliant cable, integrates it inside a non-construction product (for example a server rack or a cabinet) and resells the cabinet does not redeliver a CPR DoP for the cabinet, but must retain the supplier DoPs in the technical file. Where the same integrator delivers cable that is then pulled into the building infrastructure, the CPR DoP travels with the cable.

Systems of Assessment and Verification of Constancy of Performance (AVCP)

CPR defines five AVCP systems labelled 1+, 1, 2+, 3 and 4. The level fixes who does what: who runs the initial type test, who audits the factory production control (FPC), and who carries out ongoing surveillance.

System	Initial type test	Factory production control audit	Ongoing surveillance
1+	Notified product certification body	Notified product certification body	Continuous, including periodic re-sampling
1	Notified product certification body	Notified product certification body	Continuous
2+	Manufacturer	Notified factory production control certification body	Continuous
3	Notified test laboratory	Manufacturer	None by notified body
4	Manufacturer	Manufacturer	None

For each hEN, the European Commission decides which AVCP system applies to which level of declared performance. EN 50575 uses three AVCP levels indexed on the declared Euroclass:

AVCP system 1+ applies to cables declared Aca, B1ca or B2ca. A notified product certification body (Notified Body, NB) performs initial type testing, audits the manufacturer FPC, and carries out continuous surveillance with periodic re-sampling. The NB issues a Certificate of Constancy of Performance.
AVCP system 3 applies to cables declared Cca, Dca or Eca. A notified test laboratory performs initial type testing and issues a test report. The manufacturer implements and maintains FPC. No NB surveillance is required for the FPC after the initial type test.
AVCP system 4 applies to cables declared Fca, the lowest Euroclass meaning no performance determined. The manufacturer self-declares; no notified body is involved.

The choice of AVCP system is not optional for the manufacturer; it follows automatically from the declared Euroclass. A cable manufacturer who decides to upgrade from Cca to B2ca therefore steps from system 3 (test-report-based) to system 1+ (continuous NB surveillance), with a structural impact on cost and on the FPC documentation.

EN 50575 Euroclasses

EN 50575 defines seven principal Euroclasses for cables, mirroring the EN 13501-6 classification scheme.

Euroclass	Reaction-to-fire performance	Typical use
Aca	No contribution to fire	Highest performance, rarely commercially available for cables
B1ca	Very limited contribution to fire	Critical escape routes, very-high-risk areas
B2ca	Limited contribution to fire	High-rise buildings, hospitals, escape routes
Cca	Some contribution to fire	Office buildings, public buildings, commercial spaces
Dca	Acceptable contribution to fire	Residential, lower-risk applications
Eca	Acceptable reaction in single-cable vertical flame test only	Low-risk, low-density installations
Fca	No performance determined	Outside performance-driven scopes

The principal class is supplemented by three additional ratings that qualify the smoke, the burning droplets and the acidity of the gases produced.

Additional rating	Meaning	Levels
s (smoke)	Smoke production rate and total smoke production	s1 (best), s1a, s1b, s2, s3
d (droplets)	Flaming droplets or particles	d0 (none), d1, d2
a (acidity)	Acidity of the gases evolved	a1 (best), a2, a3

A typical declared performance reads as Cca-s1,d1,a1 for an office-grade reference. The s1a and s1b sub-ratings further refine s1 on the basis of light transmittance during the EN 50399 smoke test. The Euroclass and its sub-ratings are not orthogonal options; they form a single declared performance string and the test programme must cover all of them simultaneously.

Test methods feeding the Euroclass

The classification is built from four test methods. The notified body or test laboratory selects the applicable subset depending on the targeted Euroclass.

Test method	Standard	What it measures
Large-scale flame spread, heat release and smoke production on bunched cables	EN 50399 (2011)	Flame spread length, peak heat release rate (HRR), total heat release (THR), peak smoke production (SPR), total smoke production (TSP)
Single insulated wire or cable, vertical flame test	EN 60332-1-2 (2004)	Vertical flame propagation on a single sample with 1 kW pre-mixed flame
Smoke density on burning cables in a 3-metre cube	EN 61034-2 (2005)	Light transmittance during cable combustion in a defined chamber
Halogen acid gas and acidity of evolved gases	EN 60754-1 and EN 60754-2 (2014)	Mass of HCl and other halogen acid gases (part 1), conductivity and pH of the gases (part 2)

EN 50399 is the central test, both the largest in scale and the most expensive to run. A test rig holds a representative bundle of cables vertically, exposes them to a calibrated propane burner at the base, and measures heat release rate, smoke production rate and flame spread length over a defined test duration. EN 60332-1-2 is a much smaller bench test on a single insulated wire and is the minimum test required even for Eca. EN 61034-2 uses a 3-metre cube test chamber, with a defined cable load burnt by an alcohol bath, and measures light attenuation through the chamber walls. EN 60754-1 and -2 use a tube furnace to gather combustion gases and quantify their halogen acid content (part 1) and their conductivity and pH (part 2).

A Cca-s1,d1,a1 cable must pass EN 50399 with bounded heat release and flame spread, EN 60332-1-2 on the single-wire test, EN 61034-2 for the s1 smoke threshold, and EN 60754-2 for the a1 acidity threshold. A B2ca cable must pass the same battery with stricter EN 50399 thresholds. An Eca cable is verified only by EN 60332-1-2.

Declaration of Performance and CE marking

The DoP is the mandatory document under Article 4 of CPR. Its content is fixed by Annex III and must accompany every construction product placed on the EU market.

DoP field	Content
Unique identification code	Product type identifier traceable to the technical file
Type, batch or serial number	Product identification at the unit level
Intended use	The intended use(s) as defined in the harmonised standard
Manufacturer	Name and contact address
Authorised representative	Where applicable
AVCP system	The system actually applied (1+, 3 or 4 for cables)
Harmonised standard	EN 50575:2014+A1:2016 for cables
Notified body	Identification number and tasks performed (where AVCP requires it)
Declared performance	The Euroclass with smoke, droplet and acidity sub-ratings
Signature	Responsible person, place and date of issue

Under CPR (EU) 305/2011, the DoP may be delivered on paper. Implementing Regulation (EU) 157/2014 already allowed electronic DoP delivery through a website. Under CPR 2.0 (Regulation (EU) 2024/3110), digital delivery is reinforced and explicitly extended to QR codes printed on the product, on the packaging or on the accompanying documents, which then point to a structured digital DoP. The CE mark affixed to a cable under CPR refers solely to the reaction-to-fire performance; it does not by itself attest to any electrical safety, mechanical strength or EMC performance.

CPR 2.0: Regulation (EU) 2024/3110

The CPR recast, Regulation (EU) 2024/3110, was published in December 2024. Most provisions apply from January 2026, with extensive transition periods for the existing harmonised standards. The recast keeps the CE marking, the DoP and the AVCP systems in place, while updating the framework around them.

Main changes relevant to cable manufacturers and to electronics integrators:

Digital DoP and product passport. The DoP becomes by default digital, with QR-code access from the product label. The recast aligns the format with the Digital Product Passport envisaged by the Ecodesign for Sustainable Products Regulation (ESPR).
Environmental and circularity essential characteristics. The recast adds new essential characteristics that may be incorporated into future revisions of harmonised standards, covering content of recycled materials, recyclability, durability and other environmental aspects.
Market surveillance and economic operator obligations. The roles of manufacturer, importer, distributor and authorised representative are clarified, in line with the New Legislative Framework adopted by Regulation (EU) 2019/1020 on market surveillance.
Notified body governance. Designation, monitoring and harmonisation of the work of notified bodies is reinforced. A notified body certificate or report issued under the original CPR remains valid for the transition period set by the recast or by the implementing act of each hEN.
Treatment of products used in 3D printing, kits and assembly on site. New provisions clarify the obligations when construction works integrate digitally produced components.
Harmonised standards process. The Commission acquires additional tools to draft and revise harmonised standards directly through implementing acts when the consensus process cannot deliver a usable hEN.

For an electronics designer specifying cables for a building installation in 2026, the practical consequence is that the DoP collected from suppliers should be readable in digital form and that the supplier should be in a position to deliver the QR-coded version once the implementing acts of CPR 2.0 take effect for EN 50575. Existing paper DoPs remain valid during the transition.

Member State implementation: how the Euroclass requirement is set

CPR harmonises the test method, the classification system and the declaration template. It does not set the minimum required Euroclass for any specific building. Each Member State sets its own performance level through national building regulations, fire safety codes and decrees.

Country	Reference framework	Typical level
France	Arrete du 25 juin 1980 (ERP), NF C 15-100, codes du batiment	Euroclasses cited in ERP fire safety regulation, typical Cca-s1b,d1,a1 for escape routes in ERP of category 1
Germany	Musterbauordnung, Landesbauordnungen, MLAR	Cca-s1,d1,a1 typical for escape routes in high-rise buildings, B2ca-s1a,d1,a1 in special cases
Italy	DM 18 settembre 2002, DM 25 agosto 2017	Mandatory CPR Euroclass since July 2017, with mapping to building category
Spain	Codigo Tecnico de la Edificacion (CTE)	Cca-s1b,d1,a1 typical for hospital and school escape routes
Netherlands	Bouwbesluit	Cca-s1,d2,a3 typical for fire-rated routes, references in NEN 1010
Nordics	National fire regulations, EN 1991-1-2 alignment	Dca-s2,d2,a2 commonly accepted for residential, Cca for commercial

The cable manufacturer declares the Euroclass; the building designer (or the integrator delivering a building-integrated electronics product) verifies that the declared Euroclass meets or exceeds the level mandated by the destination Member State for the type of building and the specific cable route. A control cable installed in a high-rise riser shaft in Germany at Eca-s3,d2,a3 may pass CPR (the DoP is valid) but fail the German building regulation; the responsibility lies on the installer and the designer, not on the cable manufacturer.

Other CPR-relevant hENs for electronics integrators

A cable is the most common construction product that an electronics company places on the EU market, but it is not the only one. Several hENs under CPR are relevant when an integrator delivers building-embedded products.

hEN	Product type	Relevance to electronics
EN 50575:2014+A1:2016	Power, control, communication cables (permanent installation)	Cable selection, sourcing and DoP collection
EN 13501-6	Fire classification of construction products, reaction-to-fire performance of electric cables	Reference classification scheme used by EN 50575
EN 50583 (BIPV)	Building-integrated photovoltaic modules	PV installer placing BIPV products on the market, with overlap on IEC 61730 safety
EN 60670 family (parts listed as hENs)	Boxes and enclosures for electrical accessories in fixed installations	Wall-embedded boxes installed in the building structure
EN 50085 family	Cable trunking and ducting systems for electrical installations	Embedded trunking in walls or floors
EN 61386 family (where listed)	Conduit systems for cable management	Embedded conduit
EN 54 series	Fire detection and fire alarm systems	Detector heads, control panels (mandatory CE under CPR)

For each of these, the AVCP system, the essential characteristics and the DoP template are defined in the harmonised standard. An integrator delivering a building electronics product should map all the construction-product items in the BoM and collect the DoP from each supplier into the technical file. For the radio and wired-protocol side of building products, see KNX, DALI-2 and EnOcean certification where applicable; the alliance certification is independent of CPR but the two files coexist in the same technical documentation.

Common pitfalls in a CPR file for an electronics integrator

Confusing LSZH with a Euroclass. A purchase order that specifies LSZH but does not specify a Euroclass leaves the legal reaction-to-fire requirement undefined. The DoP is written in Euroclass terms; the building regulation that the project must satisfy is written in Euroclass terms. LSZH may be a useful manufacturer marketing tag but does not by itself satisfy CPR.
Re-spooling and re-branding without retesting. A buyer who takes a CPR Cca-s1,d1,a1 cable from a Tier-1 manufacturer, respools it under its own brand and re-issues the DoP creates a new product type. The DoP can be transferred only if the entire AVCP chain is preserved and the manufacturer of record is correctly identified. A common audit finding is a private-label cable carrying a DoP issued by the rebrander rather than by the original manufacturer, with no retest backing the new claim.
Substituting a sheath or insulation compound without re-testing. A cable compound change, even when nominally equivalent in chemistry, may shift the EN 50399 heat release curve, the EN 61034-2 smoke density or the EN 60754 acidity. Each compound substitution must be evaluated and, in most cases, requires a fresh initial type test for the affected Euroclass.
Specifying CPR on a cable that is not within scope. Cables placed inside an appliance, a machine, a piece of furniture or a non-fixed product are not construction products. Asking a supplier for a CPR DoP on a server-rack internal harness is technically meaningless; the supplier may decline or may provide a DoP that does not bind anyone. The applicable framework is LVD plus the relevant EN 50525 part.
Booking a notified body before the AVCP system is known. Cables targeting Cca, Dca or Eca only need a notified test laboratory under system 3, not a notified product certification body. Engaging a system 1+ NB for a Cca product overpays for the route and slows the timeline. The AVCP follows from the targeted Euroclass.
Missing the Member State minimum Euroclass. A cable that holds a valid CPR DoP at Eca-s3,d2,a3 is legally on the market but is not necessarily fit for a German high-rise escape route. The DoP shows what was declared; the building regulation in the destination country sets the minimum. A typical project finding is a cable selection driven by price that does not meet the German DIN VDE 0100 application or the French ERP article EL.
Conflating CPR CE marking with LVD CE marking. CE on a cable under CPR refers to the reaction-to-fire performance and is backed by a DoP. CE on an appliance or a piece of equipment under LVD refers to electrical safety and is backed by a Declaration of Conformity (DoC). The two documents are different in legal nature, in scope and in content; an audit that confuses them is a recurring non-conformity.
Letting the DoP go stale after a notified body change. When a notified body designation lapses or transfers (a frequent event during CPR 2.0 transition), certificates carry over only under the conditions set by the implementing act. The DoP must be updated to reference the current NB number and certificate identifier. A DoP citing a designation that no longer exists is invalid.

Practical workflow for an electronics product placing CPR cable on the EU market

A consolidated workflow for a designer or integrator whose product introduces a CPR-scope cable into the building infrastructure:

Identify the cable scope. Establish whether the cable is permanently installed (CPR scope, EN 50575) or not (LVD scope, EN 50525 or other). Document the call.
Identify the destination Member States. Collect the minimum Euroclass required for each target market and building category. Take the most demanding as the design target.
Choose the Euroclass and the AVCP system. Map the chosen Euroclass to the AVCP system: 1+ for Aca/B1ca/B2ca, 3 for Cca/Dca/Eca, 4 for Fca.
Engage the notified body or notified test laboratory. For AVCP 1+, an NB designated for EN 50575 takes initial type testing, FPC audit and continuous surveillance. For AVCP 3, an accredited notified test laboratory issues the type test report.
Run the test programme. EN 50399 + EN 60332-1-2 for the principal class; EN 61034-2 for the s rating; EN 60754-1 / -2 for the a rating. Plan re-sampling for AVCP 1+.
Set up factory production control. Document the FPC procedures: incoming compound checks, production-line traceability, batch records, periodic in-house tests. Under AVCP 1+, the NB audits the FPC and renews the certificate periodically.
Draft and issue the Declaration of Performance. Use the Annex III template (CPR 305/2011), or the digital format prepared under CPR 2.0 once the implementing acts apply.
Affix the CE mark. The CE mark must appear on the cable or on its packaging, with the unique identification code of the product type and the NB number where applicable.
Deliver the DoP with each batch. Paper, electronic or QR-coded; the recipient (installer, distributor, integrator) keeps the DoP for ten years.
Monitor CPR 2.0 transition. Track the implementing acts that revise EN 50575 under CPR 2.0; align the digital DoP format and the product passport content as those acts enter into force.

What to remember

CPR (EU) 305/2011 governs construction products placed on the EU market, including cables permanently installed in buildings. CE marking under CPR is backed by a Declaration of Performance referring to a harmonised European standard listed in the OJEU.
EN 50575:2014+A1:2016 is the hEN for power, control and communication cables intended for permanent installation in construction works subject to reaction-to-fire requirements. It defines seven Euroclasses (Aca, B1ca, B2ca, Cca, Dca, Eca, Fca) with smoke (s), droplet (d) and acidity (a) sub-ratings.
AVCP system depends on the declared Euroclass: 1+ for Aca/B1ca/B2ca (notified body, continuous surveillance), 3 for Cca/Dca/Eca (notified test laboratory, manufacturer FPC), 4 for Fca (self-declaration).
Test methods feeding the Euroclass: EN 50399 (large-scale flame spread, heat release, smoke), EN 60332-1-2 (single-wire vertical flame), EN 61034-2 (smoke density 3-metre cube), EN 60754-1 / -2 (halogen acid gas, conductivity and pH).
CPR 2.0 is Regulation (EU) 2024/3110, published in December 2024. Most provisions apply from January 2026, with transition periods. Key changes: digital DoP and product passport, environmental essential characteristics, reinforced market surveillance and NB governance.
Member State responsibility is to set the minimum Euroclass for each building category; CPR harmonises the test method and the classification, not the level. France, Germany, Italy, Spain, the Netherlands and the Nordics each publish their own indexed framework.
LSZH is not a Euroclass. Specifying LSZH does not satisfy CPR; the legal language is the Euroclass with its sub-ratings.
The recurring traps are confusing CPR CE with LVD CE, respooling a base cable under a new brand without retest, substituting compounds without re-running EN 50399, and missing the Member State minimum even when the DoP is valid.
