ISO 5659-2 NES 711 Plastics NBS Smoke Generation Optical Density Tester

Description:

ISO 5659-2 Plastics Smoke Generation Optical Density Test Apparatus by Single Chamber Test is widely used in assessing characteristics of vehicle interior and inflammable cable. Measure the optical density of smoke when a certain thick specimen is exposed to a heat source of 25KW/m2 or 50KW/m2.

Standards:

ASTM E 662 Standard test method of specific optical density of smoke by solid material

BSI 6401 UK Standard of measuring specific optical density of smoke by material

ISO 5659-2 Plastic smoke generation, determination of optical density by a single chamber test

NES 711 Measure the smoke density index of a small specimen burning
