BSS 7239 Test method for Aviation Material Toxicity Testing Device

Whether in flight or on the ground, fire is always one of the most dangerous threats to aircraft.
Therefore, in order to ensure the safety of air transportation, it is necessary to improve the understanding of the danger of aircraft fires; understand the causes of aircraft accidents and fires and the characteristics of aircraft fires, and master the methods of aircraft fire prevention.
BSS 7239 Aviation Material Toxicity Testing Device-Test Overview
The fumes from the pyrolysis and combustion products of combustibles contain a large amount of toxic gas components. When these product gases accumulate to a certain concentration, they will cause poison to the human body. Therefore, the toxicity of smoke and the thermal effects of fire constitute two key factors in fire risk assessment.
BSS 7239 analyzes the amount of gas produced in a specific smoke box using standard smoke generation test methods.
For the analysis of BSS 7239 toxic gas, the test device is in accordance with ASTM E 662 standard, and the test mode is two modes: open flame and unopen flame.


BSS 7239 Aviation Material Toxicity Testing Device-Test Requirements
The following gases are required to be measured by this standard
- Carbon monoxide CO
- Hydrogen fluoride HF
- Hydrogen chloride HCl
- NOx
- Sulfur dioxide SO2
-HCN, etc.
Difference between BSS 7239 and BSS 7238
BSS 7239 measures the content of smoke toxic gases generated during the combustion of materials, while BSS 7238 measures the content of smoke density generated during the combustion of materials. Among them, BSS 7239 analyzes the content of toxic gases by means of smoke generation, and BSS 7238 measures the content of smoke by measuring the attenuation of the light beam.
