Smoke Density and Toxicity Testing

Southwest Research Institute^® (SwRI^®) performs smoke density and toxicity tests to a variety of standard procedures. Standard tests are supplemented for customized procedures to meet client-specific needs. Qualification and verification testing can be provided in support of third-party quality assurance programs.

Capabilities

• Smoke density (specific optical density, Ds) and mass loss measurements
• Time evolution toxic gas production
• Gas yield determinations (amount of gas produced per gram of sample consumed)
• LC50 and LA50 determination
• Collection of gas samples for a variety of chemical analyses

Related Services

• Fourier transform infrared (FTIR) quantitative and qualitative gas analysis
• FTIR custom calibration and quantification
• Colorimetric (Dräger) tube toxicity analysis
• Listing, labeling and follow-up inspection services

Smoke density measurements are made based on the attenuation of a light beam through smoke accumulating within the chamber.

	Toxicity of fire effluents is determined by introducing gas samples in an FTIR spectrometer.
