【Scope of application】
The determination of smoke density is an important aspect of evaluating the combustion characteristics of cables or optical cables, which is related to the evacuation of personnel and the judgment of whether they can be close to extinguish the fire. This instrument is mainly used to determine the smoke concentration released by cables and optical cables when burned under specific conditions, and to verify the smoke density generated. In flame-burning or flameless combustion conditions, light transmittance is used as a way to compare different cables or fiber optic cables under specific conditions.
【Relevant Standards】
It complies with Part 1 "Test Device" and Part 2 "Test Procedures and Requirements" in GB/T17651.1~2 and IEC61034-1~2 "Determination of Smoke Density of Combustion of Cables or Optical Cables under Specific Conditions".
