New cable requirements: CPR EN50575. Where, what class of cable should be used?

Under the new law, it is no longer possible to install and design installations in buildings on the existing power, control and telecommunications cables.
The existing system for assessing the level of product resistance to flame spreading has been replaced by a new classification in accordance with the EN50575 standard. There are seven new classes: Aca, B1ca, B2ca, Cca,
Dca, Eca and Fca.

A lot of information about these classes and tests can be found on the Internet, but I cannot find the most important information: In which building and in what room, what class of cable can be used? Has anyone looked at this topic in detail?

PS I wanted to put this topic in the "Regulations and legal acts" section, but only moderators can do it.

Under the new law, you can't anymore

In order for a topic to be included in the regulation section, it must contain specific data. What is this "new law"? Provide all source details, otherwise it is useless information.

Regulation (EU) No. 305/2011 of the European Parliament and of the Council, which introduces new requirements for cables and wires as construction products.

According to the EU Official Journal No. C378 / 03 of October 13th, the new law came into force on July 1st 2017.

In accordance with PN-EN 50575, all power cables and wires that are intended for permanent installation in buildings, such as installation wires, 1kV cables, etc., are construction products.

The standard introduces a new concept of "conductor class" and defines each of them, such as A, B1, B2, C, D, E, F. Each class has been assigned specific parameters that must characterize its corresponding product. The relevant threshold values must be checked for compliance with the classification by means of laboratory tests in an independent test facility.

And the links? Where can the reader find it? Best for official sources, not studies.

Here are all the links to the topic about CPR.

The worst thing is that there is no info about which class to use cables in a given facility.

I suspect that this new EN50575 standard explains a lot. If someone has access to it, it would be nice if he wrote when and what class cables should be used.

For example, the Terms of Reference for works for PGE already include the following requirements:

All cables must be "flame retardant" according to IEC 60332-1.
All cables must be "flame retardant" in accordance with IEC 60332-3-24 (Cat. C), and the smoke generated by combustion should exhibit high light transmittance in accordance with IEC 60754-1, IEC 60754-2 and IEC 61034.

It seems that only the "orange" ones meet the above requirements, but it is the client's requirement, only the standards referred to in the regulation are obligatory.

All cable manufacturers boast that they have already adapted. They have tests, certificates, etc.
But how to design and install it when there are up to 7 classes to choose from?

I did some digging with my friend and the shortest writing looks like this:
1. Regulation of the EU Parliament No. 305/2011 threw cables into the sack of construction products.
2. Therefore, manufacturers must test the cables according to EN 50575: 2014 standard
3. Details on testing and application of a given class of cables are included in the related standard EN 13501-6
4. The EN 50575 standard was announced in the official journal on 10.06.2016.
5. According to the EU Official Journal No. C378 / 03 of October 13, the new law came into force on July 1, 2017.
Most of this concerns tests and certificates.

For us, the most important thing is where to use the cable. In short, in most buildings, cables of the minimum class should be used: Dca-s2, d1, a2.

But Note! Escape routes, i.e. in corridors where we often run main cable routes, must be in the minimum class: B2ca-s1b, d1, a1

What to do when crossing the corridor? Change the cable? Or maybe put it all in class B. (I wonder how much it costs). Or maybe building cable routes against fire? A bit of a fuss. Good luck with design and installation and commissioning ;)

Since I got into the topic, I'll throw it into the stove I recommend additional reading:

1. REQUIREMENTS FOR CABLES AND WIRES ARISING FROM THE REGULATION OF THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION NO. 305/2011 OF MARCH 9, 2011 (CPR) - mgr inż. Julian Wind Link

2. Standard N SEP-E-007

3. SEP's position

4. Guide for cables and wires covered by the CPR Regulation - issued by Tele-Fonika Kable. Link

And what's up on the contracting market in the CPR regulation? Have you dear contractors collided with this problem on the construction site?
