Portwest Bizweld Work 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 Bizweld Work range: ATPV 11.2 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 are the differences between NFPA 2112 and NFPA 70E? NFPA 2112 is the flash fire standard for flame-resistant garments; NFPA 70E is the workplace electrical safety standard whose Table 130.7(C)(15)(c) sets PPE categories by arc rating. The Portwest Bizweld Work range: Yes, every style we stock carries NFPA 2112 (flash fire) in Portwest's standards list; the ratings table shows which. Arc ratings: ATPV 11.2 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 Bizweld Work range: ATPV 11.2 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.
