Min cal rating 25 cal/cm²
Combined Ebt/ATPV Ratings Garments can be layered to achieve an overall Arc Thermal Performance Value (ATPV) or Energy Break open threshold (Ebt) Rating. For example, thermals may achieve an Ebt of 4.3 cal/cm2, and an outer coverall may achieve an ATPV of 13.6cal/cm 2 . However the combination ATPV will be greater than the sum of the two single layers, as the air gap between the two layers affords the wearer additional protection.
