FRISTADS Trousers 2074 ATHS Hi-Vis Yellow/Navy - Class 1, 10,5 cal/cm²

Fristads 2074 ATHS Hi-Vis Arc Flash Trousers, Class 1, 10,5 cal/cm²

The Fristads 2074 ATHS is a pair of Flamestat high-visibility craftsman trousers built for people who work around energised equipment. They are approved to EN 61482-1-2 Class 1 (box test) and tested to the open-arc method EN 61482-1-1 with an EBT of 10,5 cal/cm² and HAF of 81,4%, so they carry a genuine arc rating rather than a generic flame-resistant claim. If you are unsure what that distinction means, our guide to the difference between arc rated and flame resistant clothing explains it plainly.

Standards and Protection

Beyond the arc rating, the trousers are certified to EN ISO 11612 A1 B1 C1 F1 for heat and flame, EN 1149-5 for electrostatic dissipation, EN 13034 Type PB [6] for limited chemical splash, and EN ISO 20471 Class 1 for high visibility. They are OEKO-TEX certified and leasing laundry-tested to ISO 15797, which matters if your garments go through an industrial laundry contract. Fristads also publish certified garment combinations achieving EN 61482-1-2 Class 2, worth knowing if your arc flash study calls for higher protection on certain tasks.

FAQs

Are these trousers arc rated or just flame resistant?

They are arc rated. The 2074 ATHS is approved to EN 61482-1-2 Class 1 and tested to the open-arc method EN 61482-1-1 with an EBT of 10,5 cal/cm². That is a measured arc rating, not simply a flame-resistant fabric claim.

Are the trousers suitable for industrial laundry?

Yes. They are leasing laundry-tested according to ISO 15797, so they suit rental and industrial laundering programmes. Always follow the care label, as incorrect washing can degrade flame-resistant and arc-rated performance over time.
