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. A 12-month grace period was given, which ends 1st July 2017. From this point 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.

Construction Products Regulation

Declaration of Performance

The Declaration of Performance 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.

CPR Testing

Belden Preparations

To make sure all Belden cabling products comply with necessary CPR rules, Belden has been working diligently.

By making investments in state-of-the-art equipment and dedicated resources, we have set up in-house testing facilities.

Belden can now measure cabling product reaction to fire tests per EN 50399 standards, including

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

Following a demanding test schedule, Belden cables will be tested and certified to comply with CPR rules. Many cables are currently already being supplied to our customers in line with all CPR requirements.

Belden has also made back-office preparations to get ready to properly serve customers with all of their CPR responsibilities and requests. We’re adjusting:

  • Databases and online generators
  • Labeling, CE markings and cable printing
  • Part numbers and pricing
  • CPR information readily available

CPR Facility Audits and Processes

There is much more to preparing for testing CPR besides building the test apparatus and testing the cable, a lot of other actions have to be performed. There are 4 audits, of the: manufacturing plant; systems; people and technical test as well as strict guidelines on sample picking and witnessing the tests.

Verification of consistency of performance plant audits

For manufacturing plants producing products in the AVCP 1+ system (Euroclass B1, B2 and C) a half-yearly plant audit is required. These Audits focus mainly on the measures the manufacturer has in place to guarantee the constancy of the products quality.

Belden’s plants have passed these audits without issue, after testing from a CPR Notified Certification Body.

System Audit

A CPR Notified Certification Body, also completed the so called “System Audit” on the Belden processes. This audit focuses on the administrative processes of the actual testing procedure. During the audit, quality control procedures, as well as testing system processes, are checked and audited. The testing system process means the auditor reviews how the samples are collected, stored and conditioned. Samples, should for instance, not be stored randomly and should also be clearly identifiable. Additional checks are made on sample traceability; can Belden verify where reel X comes from, who produced it and if there were any defect registered during manufacturing.

Staffing Audit

Staffing Audit of those within the Belden Test labs is also carried out. Two tests are currently being done for CPR, the NEN-EN-IEC 60332-1-2 and the NEN-EN 50399 test. During the audit the auditor checks whether the persons actually doing the tests are completely independent (not managed or influenced) from the persons responsible for the manufacturing of the cables.

Technical Audit

Belden was also audited for the technical part of the CPR tests. This audit focused more on the actual test apparatus. The whole apparatus is checked for compliance with the appropriate standard, from the actual geometry of the test chamber, to the calibration data and certificates of individual components.

The technical Audit takes about a working day. The audit is carried out by a CPR Notified Laboratory.

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 chooses from the manufacturing plant the reel containing the material to be tested, they identify it by placing a sticker on it. This sticker is numbered; 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.

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

What is CPR?

CPR stands for “Construction Products Regulation”, which are 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.

When does CPR become applicable?

CPR has officially come into force as of June 10, 2016. The transition period will end one year later, in July 2017.

For whom is CPR applicable?

CPR language applies to architects, engineers, contractors, member states, manufacturers and end users. It must be used when specifying requirements and selecting products.

What are Euroclasses?

Euroclasses are uniform assessment methods or classifications that reflect real-life environments for building products based on reaction-to-fire performance. The Euroclass Table defines seven classes for the reaction to the fire performance of cables. Heat release and flame spread are the main classification criteria; smoke production, flaming droplets and acidity are additional classification criteria.

How do Euroclasses compare with other (international) fire standards?

CPR Euroclasses address all aspects of a cable’s behavior during a fire. Behavior is measured against time on real size samples.

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

After July 1st, the use of IEC standards on CPR applicable cables is prohibited.

What is a Declaration of Performance?

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 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.

What is a CE marking?

The CE marking allows a product to be placed legally on the market in any member state. It indicates that a product is consistent with the manufacturer’s Declaration of Conformity/Performance.

Which cables are involved in CPR?

All power, control and communication cables that are installed in fixed installations in buildings and other civil engineering works.

Which buildings are involved in CPR?

All buildings and civil engineering works are involved in CPR.

Which applications are involved in CPR?

According to the CPR framework the actual performance level required for any particular regulated application is a National matter.

Basis for country CPR-level decisions can include e.g. Fire risk, Ease of Escape in case of fire or exposed area of cable surface.

What is AVCP?

AVCP stands for “Assessment and verification of constancy of performance”, which requires that the compliance of power, control and communication cables with the requirements of CPR and with the performance (including classes) declared by the manufacturer in the Declaration of Performance (DoP) shall be demonstrated by:

  • determination of the product-type,
  • factory production control by the manufacturer, including product assessment.

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

What is the responsibility of manufacturers in CPR?

Before placing a product on the market, there are certain rules that manufacturers must follow. First, manufacturers must make a Declaration of Conformity/Performance stating the Euroclass performance of the specific product. Then they must affix the CE marking and keep all documentation for 10 years. Depending on the Euroclass of a product they are also required to monitor the product (including selftesting of samples) following additional AVCP requirements. Furthermore they must ensure that it is identifiable, list contact information on the product and provide instructions and safety information in appropriate languages. Manufacturers must also take corrective measures when necessary, and cooperate with any requests from authorities.

What is the responsibility of end users in CPR?

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.

What is the responsibility of integrators in CPR?

Integrators have a list of responsibilities that are 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.

What is the responsibility of importers in CPR?

Importers are required to follow several steps as part of CPR. First, they must verify that manufacturers have done everything required to comply with CPR rules, including additional requirements as determined by the AVCP rules. Next, importers should make sure that their own name and contact details are visible on the product, its labeling or the product’s associated documents; instructions and safety information must also be in the appropriate language of the particular 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 kept for 10 years by importers. Importers must take corrective measures when necessary, and cooperate with any requests from authorities.

What is the responsibility of distributors in CPR?

As part of the project team, distributors must ensure that the product is compliant and has all documentation to verify CPR compliance. All instructions and safety information must be in the appropriate language of the particular market. Distributors should check to see that the manufacturer has made the product identifiable, and that the manufacturer’s/importer’s contact details are visible. If products are stored or moved by the distributor, it must be done in such a way that compliance isn’t 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 name, or modifies a product in any way, the distributor is then viewed as the manufacturer.

How do countries implement CPR?

Currently many countries have their own national fire regulations. This has not allowed for free movement of products in Europe; national laws that contain essential product requirements are not harmonized. CPR rules will change this. The rules will be applied without differences of interpretation by each member state.

How do countries determine which Euroclasses are required?

Each country decides how CPR Euroclasses are used in construction standards or regulations. With most countries having introduced their CPR implementation by now we can see big differences in which Euroclasses are going to be required per country. Many countries prescribe Euroclasses between Eca and B2ca, depending on the building type or application, but exceptions exist. Therefore, it is always important to check the national CPR implementation for each country.

See our recent Blog for more information.

Or for detailed information plans can be accessed by contacting the relevant National Country Body responsible for the implementation here.

What are Notified Bodies?

A notified body is an independent, third-party body recognized by the European Union. CPR includes three types of notified bodies: product certification body, factory production control certification body and a testing laboratory.

What is the difference between “reaction to fire” and “resistance to fire”?

“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?

What does Belden do to support compliance with CPR?

Belden has made significant investments to make sure its cable products comply with CPR rules. Its cross- functional team of research and development, product management, production, quality and purchasing experts has ensured that all of relevant cables are tested, the applicable CPR levels of performance for products are identified and third-party approvals are obtained from notified bodies; Declarations of Conformity/Performance and CE markings will then be available. In line with AVCP requirements Belden will demonstrate compliance to CPR, the Euroclass performance as declared by the Declaration of Performance (DoP) and will have the necessary means to take responsibility for the conformity of the product with its declared performance.

How can Belden help make sure I comply with CPR?

From end users and consultants to systems integrators and distributors, Belden has the knowledge to help all team members successfully deal with new CPR requirements. A CPR “mini guide” has been made available by Belden, offering all parties the information they need about CPR background, regulation details and implications of the new rules.

How can I recognize a genuine CE-marked cable?

On the Declaration of Performance and Product Label the Notified Body code is declared. This code can be verified in the database of Notified Bodies that is made available on the website of the European Union.

Will cable designs change due to CPR requirements?

Depending on the cable type, changes to design may be required to obtain certain Euroclass performance.

How is it defined that a cable is certified as Euroclass Xxx?

All cable is tested in line with the test methods of norm EN 50575 and the outcome of this test defines the Euroclass classification for a cable.
