FAQs
Is this jacket genuinely arc rated, or simply flame resistant?
It is genuinely arc rated. The Fristads 4846 has been tested under both arc flash test methods: EN 61482-1-1 open arc testing gives an ATPV of 13 cal/cm² with an HAF of 81%, and the EN 61482-1-2 box test achieves Class 1. It also carries flame and heat certification to EN ISO 11612. Verify that 13 cal/cm² covers the incident energy stated on your site labels.
What sizes does the Fristads 4846 hi-vis jacket come in?
Sizes S to 3XL. High visibility classification depends on garment size: EN ISO 20471 Class 2 applies to sizes XS to M and Class 3 applies to sizes L to 3XL. The manufacturer notes that sizes may vary between colours, so confirm your required size when enquiring.
