The EN ISO 11612 checks different aspects of the fabric, which basically are fire and flames behaviour and physical strengths. In the flame and flames behaviour, the regulation checks the radiant heat, contact heat, convective heat, heat resistance (air) and limited flame spread.
In this post, we will focus in the basic requirement to pass the “limited flame spread”, which is defined by the regulation EN 15025.This regulation consists in 2 parts, A1 (horizontal flame) and A2 (vertical flame).
. To say that a test has been successful, the “must-to-pass” are:
If the fabric pass the test fulfilling the above points, we have the first “green light” to say that the fabric is flame resistant.
