CPR compliant Cables, All Your Questions are now answered!

CPR compliant Cables, CPR remains a tricky topic. Last July 1 there were some changes regarding the CPR application for cables. How was that again with CPR and what has changed?

 

The Construction Products Regulation (CPR) contains harmonized fire safety regulations for construction products in the EU. The regulation provides a common technical language for assessing the performance of construction products. It concerns all construction products intended to be permanently incorporated in construction works. The regulation dates back to July 2013, but initially for construction products other than cable. After a transition year, the regulation has therefore been valid for building-bound cables since 1 July 2017. This means, among other things, that from this date cable manufacturers and importers may only place cables on the market that meet the fire performance standard EN 50575 as described in the CPR.

The CPR divides products into different fire classes from F to A1. With cables limited, this has so far been from Fca to B2ca, where ca stands for cable:

In addition, extra criteria have been added to the Dca, Cca and B2ca classes:

Smoke, smoke development (s) on CPR compliant Cables

This indicates the allowable amount of smoke that is released during the combustion of electrical lines and is classified as follows:

s1: almost no smoke development
s1a: s1 with more than 80% visibility
s2b: s1 with a visibility of 60% to 80%
s2: limited smoke development
s3: not according to s1 or s2

Droplets, falling burning particles (d) on CPR compliant Cables

This indicates the amount of permissible burning particles falling during the combustion of electrical lines. This is important for limiting the spread of fire and is classified as follows:

d0: no falling particles
d1: limited number of falling burning particles
d2: not according to d0 or d1

Acidity, corrosivity / acidity (a) on CPR compliant Cables

This indicates the amount of permitted combustion gases released during the combustion of electrical lines and is classified as follows:

a1: low acidity
a2: limited acidity
a3: not according to a1 or a2

Declaration of Performance (DoP) for CPR compliant Cables

Manufacturers supply CPR-approved products with a CE mark and a DoP statement (Declaration of Performance). The CE mark is affixed to the label and shows that the performance of the cable meets European standards. The label also shows the fire class and the DoP number. The declaration of performance can be obtained with the help of the DoP number. This shows that the cable has been tested according to fire and test method prescribed by the European standard CE 50575. All information can be found on the packaging and / or invoice; it is not necessary for the marking on the cable to be visible. The installer is responsible for submitting the DoP statement with the installation.

The Netherlands

The CPR therefore ensures that every cable is tested in the same way and that everyone in Europe speaks the same language about these properties. However, each country decides for itself how this is applied in practice locally. The NEN8012 has been drawn up for this in the Netherlands. This has been criticized from the start because the NEN8012 and the regulation have been put together with legal texts in which concepts are not framed and there is room for different interpretations. In addition, it contains information that contradicts the 2012 Building Decree, more about this later.

Chain responsibility

The application of the NEN 8012 standard is a chain responsibility. This means that all parties in the chain bear a responsibility:

  • The client is responsible for providing the correct information with which the installer can select the correct cable class.
  • The installer is from the effective date (July 1, 2017) legally required to use CPR certified cabling for building-related wiring for applying the correct cable and must also be able to demonstrate.
  • The wholesaler is responsible that only CPR certified cables are offered and must be able to present the quality marks and certificates.
  • The manufacturer or importer is responsible that all products are tested and certified. For the inspection, use must be made of an independent and accredited inspection body.

Fire class selection

The correct fire class can be selected with the aid of the flow diagrams and / or the risk graph in NEN 8012. By asking questions about the use function and risk factors, users arrive at the required fire class. Some manufacturers have also developed tools based on these flow charts and risk analyzes. Ultimately, 4 classes are specified in the Netherlands depending on the fire risk:

What has now changed since July 1, 2020?

As said before, the NEN8012 has been criticized from the start. It is good that there are regulations, but in the end this only works if the regulations are clear and easy to apply. Due to the contradictions and vague formulations in NEN8012, a number of players in the Turkish cable industry have united in UPCOM (Turkish Cable Manufacturers Institute) to advocate for this clarity and applicability. UPCOM Telekomunikasyon‘s efforts have certainly contributed to the changes that took effect on 1 July. Read more about this in the message from UPCOM:

We would like to inform you of the developments relating to the method for determining the fire classification of building-bound cabling. There has been a lot of confusion in the past 3 years in determining the fire classification and various stories have emerged. With the amendment of the 2012 Building Decree on 1 July 2020, there will finally be clarity for the “Turkish cable market”.

Upcom Telekomunikasyon

Upcom Telekomunikasyon, or Turkish Fiber Optic Cable supplier, is a young company consisting of members who are directly and indirectly involved in cable production, sale, installation and knowledge.

The purpose of the UPCOM Telekomunikasyon is mainly based on knowledge transfer and supporting all parties involved in cables. This could include giving master classes on cable standards and on the application of different cabling, supplying a wide range of CPR complaint Cables. In addition, the Upcom Telekomuniaksyon keeps an eye on new developments in the market.

Building Decree 2012 versus NEN 1010*

The Building Decree 2012 contains all legal construction-technical regulations that all new and existing buildings must at least comply with. These regulations relate to, among other things, safety, health, usability, energy efficiency and the environment. For example, the Building Decree 2012 designates NEN 1010 as a requirement for the construction of a safe electrical installation so that, for example, no fire can occur.

*VDE 0100 in Germany is roughly equivalent to NEN 1010 in the Netherlands. Both are derivatives of the HD-IEC 60364 series.

Legal requirements for fire classification cabling

The purpose of the Building Decree 2012 is that there are no casualties during a fire, the Building Decree does not take into account consequential damage in the event of a fire. The Building Decree 2012 contains, among other things, regulations with regard to limiting the development of fire and smoke. A determination method for fire classifications has been included for general construction products. This did not apply to cables. For the fire classification of cables, they had to rely on an equivalent solution (Article 1.3 Building Decree 2012). This will change as of 1 July 2020 because a determination method for fire classification of cabling will then also be included in a new article 2.69a.

Immediately removal of reference NEN8012: 2015 from NEN1010: 2015

In anticipation of this amendment to the 2012 Building Decree, NEN has published a supplementary sheet NEN 1010: 2015 / A1 on 27 May. With this supplement sheet, all references from NEN 1010: 2015 to the NEN 8012: 2015 standard are removed. This supplementary sheet prevents a conflict between NEN 8012: 2015 and the Building Decree 2012.

Simpler working method Building Decree 2012

The method for determining the fire classification for cabling in the 2012 Building Decree is structurally different from that in NEN8012: 2015. It will become easier for the user of the Building Decree 2012 to determine the correct fire classification of a cable. Furthermore, the installer also has the option of using a different fire classification. Selection card and manual for applying fire classification cabling in accordance with Building Decree 2012.

What to do with the current NEN8012: 2015

The situation with regard to the NEN8012: 2015 is that the installer who is used to this standard can still apply it, but will always have to verify the outcome with the 2012 Building Decree. A new NEN8012: 2020 is being developed that does match the legal requirements from the 2012 Building Decree, which are expected to be available by the end of December 2020.

Prepare yourselves for the CPR and against any change or revision

After the publication of the CPR rules, we at Upcom Telekomunikasyon immediately started working with our manufacturers to test all cables according to CPR as soon as possible. Unfortunately, some manufacturers had to be said farewell, while the relationship with other manufacturers could be strengthened. We are proud to say that from July 1, 2017 we can supply almost every cable with CPR class, but that we could also quickly supply a high class B2ca or Cca CPR compliant Cables for every application. We are still unique in this regard for some cables. We have a wide range of Data Lan Cables and fiber optic cable, installation and data lan cable with a Cca or B2ca CPR class. If you are looking for a different type of cable, please do not hesitate to contact us, there is a good chance that we can also supply this. The UPCOM Telekomunikasyon CPR compliant Fiber Optic cables are available at our website, call or email us if you are interested in this!
