Protect people from toxic smoke by testing materials using the method presented in the 2012 NFPA 269.

Vital for the development of data for use in toxic hazard modeling, NFPA 269: Standard Test Method for Developing Toxic Potency Data for Use in Fire Hazard Modeling provides a means for assessing the lethal toxic potency of combustion products produced from a material or product ignited when exposed to a radiant flux. The test method provides toxic potency data on materials and products (including composites) for use in fire hazard analysis as well as product research and development.

Revised to include updated references, the 2012 NFPA 269 includes information on:

  • Test method
  • Test apparatus
  • Hazards
  • Equipment calibration
  • Calculation
  • Analysis
  • Precision and bias

Essential for testing laboratories and manufacturers. (Approx. 19 pp., 2012)
