Computerized flooring radiant panel tester used for universal application
The pavement thermal radiation tester is developed in accordance with ISO 9239-1, ASTM E648 and GB / T 11785 test method for the burning performance of flooring materials. It can be used to determine the thermal conductivity of carpet, floor coverings and roof insulation when the flame spreads transversely. Critical heat flux values, while the material can be detected in the combustion test smoke density of the development process.
ISO 9239-1: Fire testing of flooring materials - Part 1: Testing the burning properties of floor materials using radiant heat sources.
ISO 9239-2: Fire testing of flooring materials - Part 2: Test conditions for flame spread when heat flux is 25 kw / m².
ASTM E 648: Standard Test for Critical Radiant Flux of the Floor - The cover system uses a radiant heat source.
ASTM E 970: Standard Test for Critical Radiant Flux of Loft Insulated Floor Using Radiant Heat Energy Using Radiant Heat Energy.
NFPA 253: Standard Test Method for Testing the Critical Radiant Flux of a Side Plate Coverage System Using a Radiant Thermal Energy Source (National Fire Bureau Code, Vol.6).
GB / T 11785-2005.
1, The use of blower device, the air supply to the radiation board, abandoned the practice of using air compressors in the past, because the air compressor for the intermittent, can not effectively guarantee the continuity of its gas supply
