UNE-EN 15725:2023

This document gives the procedures for preparing reports on the extended application process using the results of reaction to fire tests, fire resistance tests and external fire exposure to roof tests undertaken for fire classification of products and product families in accordance with the various parts of EN 13501. EXAPS rules limit the number of tests required by implementing methods to determine the fire classification of a range of products (e.g; range of product, larger dimensions etc.).

The fundamental consideration of EXAP is safe methods that would allow to achieve the requested fire performances for the product.

This document makes reference to extended application standards throughout; wherever this term is used it refers to either a standard prepared by CEN/TC 127 Fire safety in buildings or the relevant product standard which includes information on extended application. In some cases, where a standard is not yet published, relevant bodies may issue recommendations for use by Notified Bodies in attestation procedures for CE marking under the Construction Products Regulation (CPR).

The European system currently permits extended application rules to be included in technical specifications. CEN Technical Committees and EOTA Working groups producing these rules are asked to seek the guidance of CEN/TC 127 to ensure that their rules comply with standards prepared by CEN/TC 127. In cases where extended application rules in harmonized EN product standards and ETAs do not comply with standards prepared by CEN/TC 127 the CEN BT are informed.

The EXAP Standard does not cover the incorporation of the product into the construction works that is justified by a national rules.

Expert judgements are excluded.
