The European classification standards (EN 13501 series) define harmonised procedures for classifying the resistance and reaction to fire performance of construction products. The UK government has announced that the National Classes fire testing standards (i.e. BS 476 series) will be withdrawn from 'Approved Document B' in favour of the EN 13501 series of European classification standards. Join Peter Barker as he explains the methods used to derive European classifications for construction products, covering the following topics: · Key differences between EN 13501 and BS 476 series of standards · Test methods · Extension of scope using direct (DIAP) and extended application (EXAP) rules · Classification process · Product families

Peter will explain the process of classifying doorsets using the European classification system (EN 13501-2). Peter will explain what a doorset manufacturer needs to consider when embarking on a test programme to generate a fire and smoke classification for their doorset designs. Peter will explain why it is important to understand product families and types for the purpose of EN classification, particularly in relation to the use of direct application (DIAP) and extended application (EXAP) rules when defining design options based on test evidence.

Karl will introduce the test methods used for reaction to fire testing of construction products and fire testing of roof systems, including video footage of the products being tested at Warringtonfire’s test laboratory. Karl will explain how the different test methods relate to the EN classification process, and describe the different classes used for classifying the products based on test evidence.
