What is the BSS Test?
BSS stands for Boeing Safety Standard. Commonly abbreviated to BSS, the BSS 7239 is a test method for the generation of toxic gases by specific materials upon combustion. When materials burn or ignite, they release gases that can be hazardous to human health when they reach certain levels. BSS 7239 determines exactly which and how much toxic gases are emitted by burning a sample piece of material of three inches by three inches in a controlled setting.
The test checks for the following gases:

  • Carbon monoxide (CO)

  • Hydrogen cyanide (HCN)

  • Sulfur dioxide (SO2)

  • Hydrogen chloride (HCL)

  • Hydrogen fluoride (HF)

  • Nitrogen oxides (NOx) (Both NO, nitric oxide, and NO2, Nitrogen dioxide, are detected)

There are multiple methods of measuring toxicity levels. One of the most frequently used methods is spectrophotometry. This technique is based on the fact that different compounds absorb light differently. By shining light through the smoke that’s generated by the combustion of the test material, it becomes possible to distinguish exactly which compounds are present and in what concentration.
Common Tests Performed with this Test
This flammability test, the BSS 7239, can be performed in conjunction with ASTM E162, which exposes materials to a radiant heat source in order to test the flame spread factor and heat evolution factor. In addition, it can also be performed in conjunction with ASTM E662, which measures the smoke density of specific materials upon combustion. In this instance, the smoke generated in ASTM E662 can be tested for toxicity using spectrophotometry.
What does the Boeing Safety Standard 7239 test for?
As a highly effective toxic gas generation test, BSS 7239 is required to measure the flame smoke toxicity (FST) of composites, textiles, and coatings used in the railroad, aircraft and government sectors. The reason for this is that the materials used need to meet parts per million (PPM) standards and the results of this test show the actual concentration of toxic gases emitted during combustion of a material.
