Toxicity of fire effluents is determined by introducing gas samples in a Fourier transform infrared spectrometer.

Smoke density and toxicity tests are performed by Southwest Research Institute (SwRI) in accordance with a variety of standard procedures. Standard tests are supplemented with customized procedures to meet client-specific needs.

 

Experimental support is provided to the Listing, Labeling, and Follow-Up Inspection Services Section in the form of testing services for quality assurance of products and materials. Qualification and verification testing is provided in support of third party quality assurance programs.

 

Smoke Density and Toxicity Test Capabilities

  • Smoke density (specific optical density, DS) and mass loss measurements

  • Toxic gas production over time

  • Gas yield determinations (mass of gas produced per mass of sample consumed)

  • LC50 and LA50 determination

  • Collection of gas samples for analysis by other analytical chemistry techniques
