Fire Resistance Test Standards

Published 18 January 2023

The purpose of evaluating fire resistance is to examine how a building element reacts to specific heat and pressure conditions. This process quantifies the element's ability to withstand high temperatures by measuring its loadbearing capacity, fire containment (integrity), thermal transmittance (insulation), and other characteristics.

Within Great Britain's regulatory frameworks, British Standards and European Normative test methods co-exist as a means of demonstrating compliance. However, it's important to note that European Normatives relating to fire resistance testing have been gradually replacing their British counterparts.

Standards are technical specifications defining requirements for products, production processes, services or test-methods. These specifications are voluntary. They are developed by industry and market actors following some basic principles such as consensus, openness, transparency and non-discrimination. Standards ensure interoperability and safety, reduce costs and facilitate companies' integration in the value chain and trade.

European Standards

European Standards are under the responsibility of the European Standardisation Organisations (CEN, CENELEC, ETSI) and can be used to support EU legislation and policies.

Below, is a comprehensive list of European Standards that relate to the fire resistance of building elements.

BS EN 13501-2: 2016 - Fire classification of construction products and building elements - Classification using data from fire resistance tests, excluding ventilation services

BS EN 13501-2 is the second part of the multi-series standard that is applicable to the fire classification of construction products and building elements. It is the procedure for classification of construction products and building elements using data from fire resistance and smoke leakage tests which are within the direct field of application of the relevant test method. Classification on the basis of extended application of test results is also included in the scope of BS EN 13501-2.
