Flooring Radiant Panel Testing Equipment

Introduction:

Critical Radiant Flux is the main parameters of the fire risk for flooring materials, It reflects the burning and spreading ability of flooring material specimen under external heat radiation conditions, It is an important index of combustion classification for building products. According to ISO9239-1,2 and GB/T 11785-2005 requirements, and this tester is measuring the critical radiant of combustion floor coverings, through the radiation environment of test chamber. It is can also be used to measure the critical radiation of the cellulose insulation floor material.

Standards

• ISO 9239-1: Flooring fire reaction test - Part 1: Combustion performance of flooring materials tested by radiant heat；

• ISO 9239-2: Flooring fire reaction test - Part 2: Testing flame spread status under the heat flux is 25kW/m2；

• ASTM E 648: Critical Radiant Flux of Floor standard test - covering system uses radiant heat energy；
