REACTION TO FIRE
TESTING
Testing of construction products and building materials for the UK and European marketplace.
What is reaction to fire testing?
Reaction to Fire testing examines the characteristics, such as combustibility, of building materials to determine their contribution to fire development and spread. The results lead to a product achieving a BS EN 13501-1 (Euroclass) classification.
​
Manufacturers seeking a reaction to fire BS EN 13501-1 classification must follow a test plan in accordance with the relevant classification. The tests relating to each classification can be seen on the table below. Manufacturers selling products in the UK require a BS EN 13501-1 classification following the removal of BS 476 for reaction to fire in March 2025.
​
United Kingdom Testing & Certification offer UKAS accredited reaction to fire testing from its fire testing laboratory on the outskirts of Glasgow, serving manufacturers from across the UK and Europe. Manufacturers can expect results within hours of test followed by a test report within 10 working days of the test.

SMALL FLAME
The Small Flame test method determines the potential maximum total heat release of a product when completely burned, regardless of its end use. This determines the absolute value of the heat of combustion for a product without accounting for inherent product variability.
BS EN ISO 1182:2020
NON-COMBUSTIBILITY
This test identifies products that will not, or not significantly, contribute to a fire, regardless of their end use. This test has been developed to identify construction products which produce a very limited amount of heat and flame when exposed to temperatures of approximately 750°C.
Reaction to Fire Test Costs
Reaction to Fire testing can vary in price depending on a number of factors including product colour, size and end-use. Test programs for reaction to fire testing and a 13501-1 classification report range between £2,000 - £5,000.
​
For a typical Euroclass B, C or D project, this would include 2 test and 1 classification for £3,995 + VAT.
