> Smoke Density Test Machine For Wire And Cable

According to GB/T17651.1~2 and IEC61034-1~2,the first parts of "test device" and second part of "test steps and requirements" for the determination of smoke density of cables or optical cables under specific conditions. The determination of smoke density is an important aspect of assessing the combustion characteristics of cable or cable, which is related to the evacuation of the personnel and the determination of the proximity of the fire extinguishing. This instrument is mainly used to determi...

> smoke density chamber test

A smoke density chamber test is a laboratory test that measures the smoke density of a material when it is burned. It is often used to evaluate the performance of materials in fire situations, as well as to test the effectiveness of fire retardant treatments.
