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