Frequently Asked Questions
The basic test for flame resistance is ASTM D6413. In this test fabric specimens are exposed to a flame for 12 seconds followed by tearing the damaged area with a small weight. The length of the damaged area is measured and reported as char length. If a fabric continues to burn after the 12 second exposure has ended this burning is timed and reported as afterflame time. Every lot of our flame resistant fabric is tested by this method before and after 100 industrial wash and dry cycles to confirm the durability of the flame resistant properties.
In addition to the Vertical Burn Test (ASTM D6413), we use the Kinectrics Laboratories in Toronto for electric arc testing by ASTM F1959. Our fabrics are also tested on the thermal manikin at North Carolina State University known as PyromanTM as part of the requirements for NFPA 2112. We also use Underwriters Laboratories for 3rd party testing and component recognition to standards like NFPA 2112 and CGSB 155.20.

Flame resistance is the characteristic of a fabric to resist ignition and to self-extinguish if ignited. Flame retardant refers to a chemical substance used to impart flame resistance. Simply put, flame retardant materials may be used to make fabrics flame resistant.
