Introduction: Building material smoke density tester is used to measure the static smoke density of building materials under the test conditions of combustion or decomposition. The smoke density test is carried out by testing the loss of luminous flux in the test chamber, and flame and smoke can be observed during the test. phenomenon. Compliance with standards: ASTM D2843 GB/T 8627; Area of application: Determination of static smoke production from burning of building materials and their products and other materials. It is mainly used for the evaluation of flame retardant grade B1 of insulation materials such as extruded board and polystyrene board. Features: 1. Accurate and fast data acquisition function 2.
