BS EN 13501-2:2023, Fire classification of construction products and building elements. Classification using data from fire resistance and smoke control tests

BS EN 13501-2:2023, Fire classification of construction products and building elements. Classification using data from fire resistance and smoke control tests. This standard is a key part of the European system for classifying the fire performance of building components. It explains how to use data from various fire resistance and smoke control tests (such as BS EN 1634-1 for doors or BS EN 1366 series for installations) to produce a formal classification. This classification provides a standardised 'shorthand' (e.g., EI 60, E 90-C) that describes the performance of a product or element in terms of integrity (E), insulation (I), radiation (W), and other parameters, over a period of time, making it easier to specify and verify compliant products. This page provides a structured summary, key provisions, and practical guidance on the application of BS EN 13501-2 Reaction to Fire Class to UK fire safety engineering, building design, and Building Safety Act compliance.
