1、 Scope of application:
It is applicable to the test of paving materials placed horizontally and exposed to inclined thermal radiation field by small flame ignition.
It is applicable to all kinds of flooring materials. For example: textile carpet , Soft board , wooden board Rubber sheet and Plastic floor and floor Spraying materials. The device can reflect the combustion performance of the floor covering materials, including the used base materials. The changes in the backing materials, bottom materials or other aspects of the floor covering materials may affect the test results. It is used to test and describe the combustion characteristics of the floor covering materials on fire and heat under the control of the laboratory.
