1. Scope of Application
Test equipment for toxic risk classification of flue gases suitable for stable smoke production.
GB standard is used to test the toxicity grade of smoke produced by smoke in mice.
The ISO standard uses gas analyzers to determine the toxic risk classification of smoke produced by materials. Gas analyzer is another option.
This test machine ZONSKY company with the "Ministry of Public Security, Sichuan Fire Research Institute of Science and Technology" joint research and development, unique world-leading technology.
2. Standards
Compliance with GB/T 20285-2006 "Classification of Toxicity Risk of Smoke Producing Materials", ISO 19700-2006 "Control led Equivalence Ratio Method for the Determination of Hazardous Components of Fire Effluents"
