Reaction to fire tests for floorings — Part 1: Determination of the burning behaviour using a radiant heat source

Edition date: 2025-06-25
In Force
Available languages: French, English
Summary:

This document specifies a method for assessing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required.

This method is applicable to all types of flooring, e.g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings. Results obtained by this method reflect the reaction to fire performance of the flooring, including any substrate if used. Modifications of the backing, bonding to a substrate, underlay or other changes of the flooring can affect test results. It cannot be used alone to describe or appraise the fire hazard or fire risk of floorings under actual fire conditions.

Information on the precision of the test method is given in Annex B.



Le présent document prescrit une méthode d’évaluation du comportement au feu opposé au vent et de la propagation de flamme de revêtements de sol montés horizontalement et exposés à un gradient de densité de flux de chaleur dans une chambre d’essai, lorsqu’ils sont allumés avec des flammes pilotes. L’Annexe A fournit des détails sur l’évaluation du développement de la fumée, lorsque cela est exigé.

La présente méthode s’applique à tous les types de revêtements de sol, comme la moquette textile, le liège, le bois et les revêtements en caoutchouc et en plastique ainsi que les enduits. Les résultats obtenus par la présente méthode reflètent les performances de réaction au feu du revêtement de sol, y compris son substrat, le cas échéant. Les résultats d’essai peuvent être affectés par des modifications apportées au support, au collage sur un substrat, à la sous-couche ou par d’autres changements du revêtement de sol. Elle ne peut pas être utilisée seule pour décrire ou évaluer les dangers ou le risque d’incendie des revêtements de sol dans des conditions réelles d’incendie.

L’Annexe B fournit des informations sur la fidélité de la méthode d’essai.
