The GB/T11785 flooring material combustion test apparatus is suitable for various flooring materials, such as textile carpets, cork boards, wooden boards, rubber sheets, plastic flooring, and floor coating materials. This apparatus can reflect the combustion performance of flooring materials, including the base material used. Changes in the backing material, underlayment material, or other aspects of the flooring material may affect the test results.
Application
Suitable for various flooring materials, such as textile carpets, cork boards, wood boards, rubber sheets, plastic flooring, and floor coating materials. This device can reflect the combustion performance of flooring materials, including the substrate used. Changes in backing materials, underlay materials, or other aspects of the flooring material may affect the test results. It is used to test and describe the combustion characteristics of flooring materials in response to fire and heat under controlled laboratory conditions.
