CPR Rated Cables

CPR Compliance Detail

Ensure Your Cable Meets CPR

Belden cables undergo extensive testing to comply with Construction Products Regulation (CPR) implemented by the European Commission.  See Belden's product listing of CPR rated fiber and copper cables to meet your application's requirements.

Construction Products Regulation

The Construction Products Regulation (CPR) lays down harmonized rules for the marketing of construction products in the EU. With new rules being implemented by the European Commission (EC), construction products – including cabling for fixed installations–can no longer be used in European buildings or civil engineering works if they are not tested and certified according to the new CPR rules.

Replacing the Construction Products Directive (CPD), which was first published by the EC in 1989, CPR became applicable for non-cable products in July 2013 and officially came into force for fixed installation cable products in June 2016. The 12-month grace period ended 1st July 2017. Now all CPR applicable cable products sold must be tested and Certified to the new CPR rules.

All CPR applicable products will require Euroclass rating, CE marking and a Declaration of Performance.

Find out more in this CPR Mini Guide.

Declaration of Performance

The Declaration of Performance (DoP) expresses the Euroclass performance of cables. It defines the product, its intended use and its essential characteristics. A Declaration of Performance requires the manufacturer, importer or distributor to assume legal responsibility for the conformity of the construction product with its declared performance.

You can generate DoP certifications via the Belden Online Euroclass Checker & DoP Generator.

Euroclass Program

According to CPR, Cables will be assessed based on their performance and safety during fire situations. Analyzed in a simulated installation, measurements of flame spread, heat release, flaming droplets, smoke emission and corrosivity of gases are taken. Based on the cable’s performance, it is placed into the Euroclass system that indicates its behavior during a fire, as well as its ability to operate despite a fire. The Euroclass program provides rankings based on the following criteria:

  • Contribution to expanding a fire (rating from 'no contribution' to 'high contribution' with several levels in between)
  • Smoke production development (rating from 'limited production' to 'strong production')
  • Burning falling particles/droplets (rating from 'no droplets' to 'high droplets')
  • Class corrosiveness/acidity of combustion gases (ranging from 'low corrosiveness' to 'high corrosiveness')

Frequently Asked Questions

CPR stands for 'Construction Products Regulation'—a set of rules implemented by the European Commission. CPR rules call for products–including cables–to be tested and certified based on certain criteria before they are used in European buildings. There are six requirements against which products may be assessed. Wire and cable is covered by the 2nd requirement that addresses Safety in the case of fire.

CPR ensures that distributors, consultants, systems integrators, installers and building owners have reliable product information from different manufacturers in different countries to make accurate product comparisons. This will allow for free movement of all construction products within the European Union.
CPR officially came into force in June 2016. The transition period ended 1st July 2017 requiring all applicable cable products now be tested and certified to CPR rules.
The UKCA mark came into effect on January 1st 2021. The transition period ends 1st January 2023 requiring all applicable cable products now be tested and certified to CPR rules.
CPR language applies to architects, engineers, contractors, member states, manufacturers and end-users. It must be used when specifying requirements and selecting products.

Euroclasses within the EU and UKCA for UK are uniform assessment methods or classifications reflecting real-life environments for building products based on reaction-to-fire performance.

Both Euroclasses and UKCA table (also referred to Euroclass Product Criteria table) define seven classes for the fire performance of cables. Heat release and flame spread are the main classification criteria. Smoke production, flame droplets and acidity are additional classification criteria.

CPR Euroclasses and UKCA address all aspects of cable behavior during a fire. Behavior has been measured against time on real size samples.

Both Euroclass and UKCA Eca has been defined with reference to IEC/EN 60332-1-2. For other classes, there is no direct relationship between existing IEC test and CPR. Basic structure of the testing rig is the same however, given different mounting requirements and the use of new parameters, test results are not comparable.

As of July 1, 2017 in the EU and January 1, 2023 in the UK the use of IEC standards on CPR applicable cables is prohibited.
A Declaration of Performance expresses the performance of construction products (including cables) in relation to the essential characteristics of those products. It identifies the product, its intended use and essential characteristics. A Declaration of Performance requires the manufacturer, importer or distributor to assume legal responsibility for the conformity of the construction product with its declared performance.
The CE Mark allows a product to be placed legally on the market in any EU member state. 
The UKCA Mark allows a product to be placed legally on the UK market in, England, Scotland and Wales. It indicates the product is consistent with the manufacturer’s Declaration of Conformity/Performance.
All power, control and communication cables in fixed building installations and other civil engineering works are covered by CPR standards.
All buildings and civil engineering works fall under CPR standards.

Based on the CPR framework, the actual performance level required for any particular regulated application is a national matter.

The basis for country-level CPR decisions can include fire risk, ease of escape (in the event of fire) or exposed cable surface area. 

AVCP stands for 'Assessment & Verification of Constancy of Performance' and requires the compliance of power, control and communication cables with CPR requirements. The performance (including classes) declared by the manufacturer in the Declaration of Performance (DoP) shall be demonstrated by:

- Determination of product-type
- Manufacturer factory production control (FPC), including product assessment

The manufacturer shall always retain overall control and shall have the necessary means to take responsibility for the conformity of the product with declared performance.

Prior to placing a product on the market, there are certain rules that manufacturers must follow.

Manufacturers must make a Declaration of Conformity/Performance stating the Euroclass or UKCA performance when applicable for the specific product. This is followed by affixing the CE and/or UKCA marking and retaining all related documentation for a period of 10 years.

Depending on a product's Euroclass and/or UKCA, manufacturers may also be required to monitor the product (including sample testing as per additional AVCP requirements). Furthermore, manufacturers must ensure the product classification is easily identifiable, provide contact information and safety instructions/information in appropriate languages. Manufacturers must also take corrective measures when necessary, and cooperate with requests from authorities.


When working with the project team to draw up specifications, end-users should refer to the harmonized technical specifications (specifically to the requirements of individual characteristics).

When choosing products for construction projects, end-users should review the Declaration of Conformity/Performance from the manufacturer. They must also check national annexes or standard recommendations, which offer guidance about appropriate minimum product performance levels. Compliance with local building regulations should also be followed by end-users.

Integrators have several responsibilities similar to those of end-users.

They should refer to the harmonized technical specifications (specifically to the requirements of individual characteristics) when drawing up project specifications. When selecting products for use in European buildings, integrators should be sure to review the manufacturer’s Declaration of Conformity/Performance. They must also check national annexes or standard recommendations for guidance on appropriate minimum product performance levels. Compliance with local building regulations should also be ensured.

Importers must follow several steps to comply with CPR standards.

They must verify manufacturers have met all CPR requirements, including additional requirements as determined by the AVCP rules. Additionally,  importers should ensure their name and contact details are visible on the product, product labeling or related product documentation. Product instructions and safety information must also be in the appropriate language for the market.

When stored or moved, products must not be altered to void compliance. As long as the product is on the market, it should be monitored. Documentation should be retained for a period of 10 years by importers. Importers must take corrective measures when necessary, and cooperate with any requests from authorities.

As part of an integrated project team, distributors must ensure that product is compliant and has all documentation to verify CPR compliance.

All instructions and safety information must be in the appropriate language of the market. Distributors should check to see that the manufacturer has made the product identifiable and the manufacturer’s/importer’s contact details are visible. If products are stored or moved by the distributor, it must be done in compliance with CPR requirements and products should not be altered.

Distributors must take corrective measures when necessary, and cooperate with any requests from authorities. When a distributor places a product on the market under its own trade nameor modifies a product in any waythe distributor is considered to be the manufacturer.

Previously, many countries maintained their own national fire regulations making the movement of products across Europe challenging.

National laws containing essential product requirements were not harmonized. The introduction of CPR standards have changed this as the rules are applied without differences of interpretation by each member state.

Each country decides how CPR Euroclasses or UKCA classes are applied in construction standards or regulations. We can see big differences in which Euroclasses are required per country, however, many countries prescribe Euroclasses between Eca and B2ca, depending on the building type or application, but exceptions exist. It is always important to check the national CPR implementation for each country.

A Notified Body is an independent, third-party entity recognized by the European Union or UK when UKCA applicable. CPR includes three types of Notified Bodies

 - Product Certification 

 - Factory Production Control Certification 

 - Product Testing Laboratory

Reaction to fire describes a cable's behavior during combustion as well as its potential contribution to the development of fire. How do the cables contribute to a fire and the consequences of a fire? 
Resistance to fire, however, describes a cable’s ability to continue operating as normal during a fire situation. How long can the cable function adequately in a fire?
Customers in need of CPR-related information can reach out to our team via cprinfo@belden.com.

Belden has made significant investments to ensure relevant cable products comply with CPR rules. Our cross-functional team of research and development, product management, production, quality and purchasing experts has ensured all of relevant cables are tested, applicable CPR performance levels are identified, and third-party approvals are obtained from notified bodies.

Declarations of Conformity/Performance and CE or UKCA markings are then made available. Aligned with AVCP requirements, Belden demonstrates compliance to CPR, the Euroclass or UKCA classes performance as declared by the Declaration of Performance (DoP) and has established the necessary means to take responsibility for the conformity of the product with its declared performance.

From end-users and consultants to system integrators and distributors, Belden has the knowledge to help ensure projects meet CPR requirements. The Belden CPR Mini Guide offers important information on CPR, regulation details and project implications.
On the Declaration of Performance and Product Label, the Notified Body code should be declared. This code can be verified in the database of Notified Bodies available on the website of the European Union.
Depending on the cable type, changes to design may have been required to obtain certain Euroclass performance.
All cable is tested in line with the test methods of norm EN 50575. The outcome of this test defines the Euroclass classification for the cable.

CPR Testing

Belden Preparations

Belden has made significant efforts to ensure our cabling products comply with necessary CPR requirements. With investments in state-of-the-art equipment and dedicated resources, we have established an internal testing facility where we measure cabling product reaction to fire tests as per EN 50399 standards. Following a demanding test schedule, Belden cables are tested and certified to meet CPR standards including: 

  • Heat release
  • Flame spread
  • Smoke production
  • Flaming droplets

CPR Facility Audits & Processes

There is more to CPR testing that building the test apparatus and testing the cable. A number of additional actions must be performed. There are four audits in total:

  • The manufacturing plant
  • Systems
  • People & technical
  • Sample picking & witnessing

Verifying Consistency of Performance—Plant Audits

For manufacturing plants producing products in the AVCP 1+ system (Euroclass B1, B2 & C), a bi-annual plant audit is required. These audits focus mainly on the measures the manufacturer has in place to guarantee the constancy of the product's quality. Belden’s plants routinely pass these audits without issue, after testing from a CPR Notified Certification Body.

System Audit

A CPR Notified Certification Body also completed the 'System Audit' on Belden processes. This audit focuses on the administrative processes of  the testing procedure. During the audit, quality control procedures as well as testing system processes are checked and audited. The testing system process includes auditor review of how samples are collected, stored and conditioned. For example, samples should be clearly identifiable and stored in an orderly (not random) manner. Sample traceability is also audited to verify a manufacturer can verify reel source (e.g, who produced it & if any defect(s) were registered during manufacturing). .

Staffing Audit

A staffing audit of those within Belden Test labs is also carried out. Two tests are currently being done for CPR—NEN-EN-IEC 60332-1-2 and  NEN-EN 50399. During this audit, the auditor checks to confirm that individuals performing tests are completely independent (not managed or influenced) by those responsible for the manufacturing of the cables.

Technical Audit

Belden has also undergone a technical audit focused on our testing apparatus. Testing equipment is thoroughly checked for compliance with the appropriate standard—from the geometry of the test chamber to the calibration data and certification of individual components. This is a full-day audit carried out by a CPR Notified Lab.

Sample Picking 

Before a test is done on the bigger NEN-EN 50399 test apparatus the sample must be picked by a Notified Certification Body. This means a 'witness' from a Notified Certification Body selects the reel containing the material to be tested by by placing a sticker on it. This sticker is numbered and this number corresponds with one reel. Using this number, the Notified Certification Body can trace back a test to a certain reel, to affirm that the correct cable was tested and keeps a database of all picked samples.


To ensure correct testing, each test must be witnessed by either a Notified Certification Body or a Notified Laboratory. All products in the AVCP 1+ system are witnessed by a Notified Certification Body and all other products are tested under the watchful eye of a Notified Laboratory.
