Fire test center will provide French Standard NF P92-503 Fire Test to Building Material

NF P 92-503 Fire test to Building materials - Standard Title
> NF P92-503: Safety against fire: Building materials – Reaction to fire tests. Electrical burner test used for flexible materials

NF P 92-503 Fire test to Building materials - Scope
This document aims to define a method for reaction to fire tests used for:
> flexible material
> tight fitting flexible wall and ceiling coatings of any thickness
> flexible filtering media of any thickness

NF P 92-503 Fire test to Building materials - Principle
The test involves submitting, under defined conditions, the test pieces to the action of:
> heat radiation
> hot gases sweeping the surface of the test pieces
If require, a pilot flame is used to cause the inflammation of the pyrolysis gas.
The time to inflammation, the persistence of the flame, the nature and the effects of combustion are noted.

NF P 92-503 Fire test to Building materials - Test Method
NF P 92-503 M rating test Classify the fire test to M1, M2, M3, M4M0 is the highest class
Observe the following Result in the test and classify the rating
> Burning Time
> Dropping
> Destroyed length
