Protect people from toxic smoke by testing materials using the method presented in the 2017 edition of NFPA 269.

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.

NFPA 269 presents information on:

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

This edition:

• Clarifies the use of animal check tests in the reporting section, as revised in a TIA.
• Revises power supply for the spark ignition figure in Chapter 5.
• Features updated references throughout.

Vital for the development of data for use in toxic hazard modeling, NFPA 269 is essential for testing laboratories and manufacturers.
