I. Scope of Application
It is suitable for testing floor materials that are placed horizontally and exposed to an inclined thermal radiation field with a small flame.
It is suitable for all kinds of flooring materials. Such as: textile 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.
Ii. Standards
Complies with GB Factory 11785 "Determination of Fire Performance of Paving Materials - Radiant Heat Source Method". The structure of this machine consists of two parts: the combustion box and the control box
It is composed of several parts.
