SR EN 15725:2023

This document gives the procedures for preparing standards and reports following the extended application (EXAP) process using the results of reaction to fire tests, fire resistance tests (including other performance characteristics e.g. smoke leakage/control and/or durability of self-closing), 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. EXAP 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.) and EXAP rules form a standardized technical agreement on the parameter changes. The fundamental concept of EXAP is the development of safe methods that provide extensions to the scope of the tested product while maintaining the required classification for the product. Test reports constitute the basis of an EXAP report. This document makes reference to ‘extended application standards’ throughout; wherever this term is used it refers to either a standard prepared
