Flooring Material Radiation Heat Flux Testing Device Complies With The Test Standards Of GB/T11785-2005 And ISO9239-1

Scope of application

It is suitable for testing floor materials that are placed horizontally with a small flame and exposed to an inclined thermal radiation field under specified conditions. It is suitable for all kinds of flooring materials. Such as: textiles, carpets, cork boards, wood boards, rubber boards, plastic flooring and floor spraying materials. This device can reflect the combustion performance of the floor covering material, including the base material used. Changes in the backing material, base material or other aspects of the floor covering material may affect the test results. It is used to test and describe the combustion characteristics of the floor covering material in response to fire and heat under laboratory control conditions.

Compliance with standards: Complies with the test standards of GB/T11785-2005 and ISO9239-1 "Determination of Fire Performance of Paving Materials - Radiant Heat Source Method".
