BSS 7239 Toxicity Test

VTEC Labs: An International Leader in BSS 7239 Testing


At VTEC Laboratories, we're in the business of keeping your company safer through our comprehensive testing solutions. One of the many testing services we offer to improve operational safety for aircraft facilities and railroads is Boeing Safety Standard (BSS) 7239 toxicity testing. With ISO 17020, 17025 and 17065 accreditation and approval to serve as a vendor for organizations such as the Port Authority of New York, we offer effective testing solutions to keep your workplace safer.

What Are BSS Tests?

Boeing Safety Standard or BSS 7239 tests are flammability tests that measure the concentration of poisonous gases that specific materials create during combustion. When certain materials ignite and burn, they can emit gases that are harmful to humans at certain levels.

The BSS 7239 test measures the concentration levels of the following gasses:

  • Nitrogen oxide
  • Carbon monoxide
  • Hydrogen fluoride
  • Hydrogen cyanide
  • Hydrogen chloride
  • Sulfur dioxide

What Does the Boeing Safety Standard 7239 Test For?

The BSS 7239 Generation of Toxic Gases Standard measures the flame toxicity of coatings, textiles and composites used in the railroad, aircraft and government sectors. BSS 7239 testing is essential for these industries, as materials used in these sectors must meet specific parts per million (PPM) standards. The test results are vital in showing the actual concentration of toxic gases during material combustion.

How to Perform the BSS 7239 Toxicity Test

BSS 7239 testing measures the amount of gases emitted when you burn a material a few inches above a flame in a contained setting. Researchers can use multiple methods to determine toxicity levels, like spectrophotometry. The basis of spectrophotometry is that all compounds absorb light in different ways. To perform this test, our lab shines a light through the smoke created from burning a material sample to determine the concentrations of the compounds present.

Tests You Can Perform in Combination With BSS 7239

One can perform the BSS 7239 test in combination with the ASTM E162 and ASTM E662 tests. The ASTM E162 test involves placing materials under a radiant heat source to determine factors such as flame spread and heat evolution. The ASTM E662 test, however, measures the smoke density of materials after they combust. For example, one can use a spectrophotometry test to measure the toxicity levels of the smoke generated in an ASTM E662 test.
