7: How are cables assessed and verified externally?

The harmonised standard requirements vary depending on the fire reaction class declared, so there are different Assessment and Verification of Constancy of Performance (AVCP) systems according to the enclosed table, which are more demanding for the upper Euroclasses. These systems are based on the participation of entities not associated with the manufacturer which, according to the name of the CPR, will be the Notified Body and the Notified Laboratory.

All the assessment and verification of constancy of performance systems require the manufacturer to carry out internal quality controls as well as to prepare the Declaration of Performance for each product.  There are three assessment and verification of constancy of performance systems:


This is the maximum requirement level and corresponds to Euroclasses Aca, B1ca, B2ca and Cca. A Notified Body must inspect and be responsible for the surveillance, assessment and control of the production, as well as control the execution of initial sample and monitoring tests by the Notified Laboratory. The frequency of the monitoring tests is the highest.


This level corresponds to Euroclasses Dca and Eca. The manufacturer must perform initial verification and monitoring tests on the products with a Notified Laboratory, but the participation of a Notified Body is not compulsory.


This level corresponds to Euroclass Fca. For the manufacturer, only the preparation of the Declaration of Performance is mandatory, and it corresponds, therefore, to the lowest requirement level.

Consequently, depending on the fire reaction class declared, there are different assessment and verification of constancy of performance systems, which are summed up in the following table:

Different European organisations have requested and obtained recognition as Notified Body or Laboratory, and manufacturers can hire any one of them. In Spain, the external Notified Body is AENOR and the external Notified Laboratory is CEIS (Centre for Tests, Innovation and Services).
