Critical Radiant Flux Flammability Testing Equipment For Flooring Panel
Application
It is used to measure the burning of materials through a certain degree of heat radiation and flame environment. It is used in various kinds of floor materials such as textile carpet, cork board, wood board, rubber board, plastic floor and floor coating material Case of the critical heat radiation value. The EU uses this test method to classify fire protection material for all European Union member countries
