Building material flame retardant tester
The tester is designed for the testing of building materials according to DIN 4102-1 and is used to determine whether a material is flame retardant or not. The tester consists of combustion chamber, burner and control instrument. The combustion chamber consists of five parts: combustion chamber, burner, specimen holder, air stabilisation layer and flue. It is equipped with computer system to realise measurement and control and data processing.
