DX8368 Plastic Smoke Density Tester ISO 5659-2 GB/T 8323 Single Chamber 10-50kW/m2 Radiant Cone Heat Flux
DX8368 Plastic Smoke Density Tester
The DX8368 plastic smoke density tester is a single-chamber smoke density measuring instrument developed in strict accordance with GB/T 8323.2-2008 and ISO 5659-2:2006 standards. It is designed to determine the specific optical density of smoke generated by plastics and other solid materials during combustion, with the maximum specific optical density (Ds max) as the test result.
Application Scope
Suitable for evaluating the smoke generation performance of all plastics, rubber, textile coverings, painted surfaces, wood and other materials. Widely used by plastic and solid material manufacturers and scientific research laboratories.
