FAQs
Is this jacket arc rated or just flame resistant?
Both. It is arc tested to EN 61482-1-1 (EBT 10.5 cal/cm²) and EN 61482-1-2 class 1, and flame resistant to EN ISO 11612. Arc-rated garments are tested specifically against the thermal energy of an electric arc.
Can it achieve EN 61482-1-2 class 2?
As a single garment it is approved to class 1. Fristads publishes certified garment combinations in its electric arc table that reach class 2, typically layering with other Flamestat pieces. Ask our team and we can confirm the current combinations.
