The NFPA 2112 standard specifies the minimum requirements for a garment to be considered “fire resistant”.

Garments which are certified NFPA 2112 must pass each of the following tests:

Heat Transfer Performance – Tests how much heat is transferred through a garment
Vertical Flammability Test – Tests how easily the fabrics ignite and continue to burn
Thermal Shrinkage Test – Tests the fabrics resistance to shrinkage when exposed to heat
Heat Resistance Test – Tests how the fabric reacts to extremely high heats
Thermal Manikan Test – An overall test on the how the fabric performs in a coverall design exposed to 3s of extreme temperatures
Thread Melting Test – Threads used in cerified NFPA 2112 garments must use threads that can withstand temperatures of 500℉

The NFPA 70E standard gives guidance for selecting the appropriate PPE in environments where an electric shock could occur.

The NFPA 70E standard breaks a garments ARC RATING into 4 categories:

ARC 1 – ARC Rated FR Shirt AND FR Pants OR FR Coverall that meets the minimum 4 cal/cm2
ARC 2 – ARC Rated FR Shirt AND FR Pants OR FR Coverall that meets the minimum 8 cal/cm2
ARC 3 – ARC Rated FR Shirt AND FR Pants OR FR Coverall + Arc Flash suit so the combined system meets the minimum 25 cal/cm2
ARC 4 – ARC Rated FR Shirt AND FR Pants OR FR Coverall + Arc Flash suit so the combined system meets the minimum 40 cal/cm2
