FAQ

Our experts will help you with questions concerning the Construction Products Directive CPR.


What happens when only a few meters are permanently installed in (a limited number of) buildings. Are these also covered by the BauPVO?

The BauPVO principally also applies if only a few meters are installed inside buildings. It remains to be seen how this directive is implemented in the corresponding directives of the federal states. We do not yet have a solution for this.

Inventories

What happens with the inventory currently in stock? Are these materials excluded from the new regulations?

A performance declaration iaw. Art. 4 EU-BauPVO must be issued for products distributed after 7/1/2017, irrespective of whether or not these are in inventory.

Many of our products have already been tested. We publish the associated link to the performance declaration on our website together with the respective products.


Cable E30 E90

Do cables with continued function E30, E90 meet BauPVO?

Cables compliant with BauPVO meet high requirements with respect to their reaction to fire.
In addition to fire propagation, the definition also includes smoke density, acidity (absence of halogens) and burning droplets (along with several others).

Cables with continued function describe the resistance to fire for the entire cable installation. Cables plus fasteners are tested in the system as to whether a short-circuit occurs in the specified time. The cable could principally be fully engulfed in flames in this case.

The one has no bearing on the other. Cables with continued function also require additional testing and the performance declaration with proof for the fire classes pursuant to BauPVO.

Who determines the requirements for the fire class?

Implementing the safety standards in buildings with high safety requirements and adjusting the current codes to the building products directive is the responsibility of the construction ministries of the individual federal states.

The construction minister conference is currently revising the construction code template,which serves as the basis for implementing the regulations in the individual federal states.

Euro-Class B2ca: nonfire B2ca
Euro-Class Cca: nonfire Cca
Euro-Class Eca: CPR Eca

Answers

What requirements does the CPR place on cables?

The intent of the Directive is to develop standardized requirements throughout Europe. The following criteria must be observed:

  • The cable's reaction to fire
    (flame propagation, heat and smoke release, speed of fire growth, burning droplet characteristics)
     
Euro-Classes Other classes Construction code

Medium
Eca       Low
Fca       Highly flammable None

Euro-Classes Aca and B1ca do not apply to plastic-insulated cables.

Based on the ZVEI proposal, only the Euro-Classes B2ca, Cca, and Eca are used in German building structures.
Bayka lists the Euro-Class Fca (flammable cables) within the previous cable product line.


Do all cables from Bayka meet the CPR

No, not all cables from Bayka are affected by the CPR.

Many cables are exterior cables for installations in-ground or in cable ducts.
For instance, telecom cables or high-voltage cables with PE jackets are intended for use outside of buildings and are therefore not covered by the applications described in the standard EN 50575, part 1.

Note:
You can find a corresponding reference for these cables in the technical descriptions.
There is also a reference in the product overview.
