Portwest Modaflame Knit FR Clothing questions

What is the minimum arc flash rating for a CAT 2? NFPA 70E Table 130.7(C)(15)(c) sets a minimum arc rating of 8 cal/cm² for PPE Category 2 and 25 cal/cm² for Category 3. The Portwest Modaflame Knit range: ATPV 9 to 22 cal/cm² on the ASTM F1959 test across the styles we stock, as published by Portwest; Portwest lists CAT 2 where it states a category. Each style page states its own figure.

What is the difference between ATPV and EBT? Both are arc ratings from the ASTM F1959 test: ATPV is the incident energy at which a second-degree burn is predicted 50% of the time, EBT the energy at which the fabric breaks open; a garment is labelled with whichever is reached first. The Portwest Modaflame Knit range: ATPV 9 to 22 cal/cm² on the ASTM F1959 test across the styles we stock, as published by Portwest; Portwest lists CAT 2 where it states a category. Each style page states its own figure.
