Frequently Asked Questions
What certifications does the FR509 carry?
The FR509 is independently certified (Aitex, cert 26/09725/00/0161/B) to EN ISO 11612 (A1+A2, B1, C1, F1) for heat and flame, EN ISO 11611 Class 1 (A1+A2) for welding, EN 1149-5 for antistatic protection, EN 61482-1-1 and EN 61482-1-2 APC 1 for arc flash, EN 13034 Type 6 for limited chemical splash, and EN ISO 20471 Class 3 for high visibility.
Is the FR509 arc-flash rated?
Yes. It's rated ELIM 6.4 cal/cm² and EBT 6.8 cal/cm² under EN 61482-1-1, and holds APC 1 under EN 61482-1-2. This is a lower arc rating than the winter jackets in the range, so check it against your site's arc flash risk assessment before use.
Can I wear the FR509 for welding?
Yes, within its rated class. The FR509 is certified to EN ISO 11611 Class 1 (A1+A2), covering less hazardous welding situations, such as lower spatter and radiant heat exposure, than Class 2.
Is the FR509 waterproof?
No EN 343 weather rating beyond the standard's Type 6 chemical splash resistance is recorded for the FR509. It's designed as a workwear coverall rather than a wet-weather garment.
Is the FR509 approved for rail (RIS) work?
The FR509 carries RIS-3279-TOM Issue 2 approval, but only in the Orange/Black colourway. The Orange/Navy option is not RIS-approved.
How should I wash and care for the FR509 to keep its FR protection?
Follow the care label sewn into the garment and avoid fabric softener and bleach based products, which can degrade flame resistant fibres over time. The FR protection is built into the fabric itself, not a coating, so it won't wash out, but retire the coverall if it's visibly damaged or fails a wash care check.
