China Plastic Smoke Density Combustion Testing Machine Manufacturer

                China Plastic Smoke Density Combustion Testing Machine Manufacturer 

A. Introduction:

The plastic smoke density combustion testing equipment is a new type of test equipment for measuring smoke density according to the technical conditions specified in the standards EN 45545-2 and ISO5659.2-2006.

This standard is applicable to the determination of the specific optical density of smoke generated by the burning of plastics, and the maximum specific optical density is the test result. It is used to assess the smoke performance of plastics under specified conditions.

The whole instrument consists of a closed test chamber, a photometric measuring system, a radiation cone, a combustion system, an igniter, a test box, a bracket, a temperature measuring instrument and a smoke density testing software; the circuit is developed by a single chip microcomputer, and has high technical content and stable performance.

Suitable for all plastics, this instrument is also suitable for the evaluation of other materials (such as rubber, textile coverings, painted surfaces, wood and other materials), and is widely used in the plastics industry, solid materials industry production plants and research and testing units.
