NFPA 2112:2018 Testing of flame-retardant protective clothing for industrial use
Article 8.3 of NFPA 2112:2018 specifies the requirements for flame resistance testing of these garments. Flame retardant testing evaluates the performance of clothing in terms of flame resistance, self extinguishing, and flame prevention when exposed to flash flames.
As stated in Article 8.3 of NFPA 2112:2018, the testing process for flame resistance testing includes the following steps:
Sample preparation: Prepare clothing samples according to specified requirements, including the quantity and size of the samples to be tested.
● Testing instruments: Use appropriate testing instruments to simulate flash ignition situations. This typically involves a propane burner or other controlled ignition source, producing a brief flame burst.
● Testing procedure: The clothing sample is exposed to flash fire in the testing equipment, and the duration and distance from the ignition source are specified. Exposure conditions are based on specific industry conditions and hazard levels.
● Evaluation: After exposure, visually inspect clothing samples to assess the extent of flame spread, damage, or ignition. In the evaluation process, criteria such as carbonization length, damaged area, and any melting or dripping should be considered.
● Pass/fail criteria: Compare the test results with the pass/fail criteria specified in NFPA 2112:2018. If the clothing meets the requirements, they are considered flame retardant and meet the standards. If the clothing does not meet the standards, further evaluation or improvement may be needed.
