Frequently Asked Questions
What certifications does the FR503 carry?
The FR503 is independently certified (SATRA Technology Europe Ltd, cert 2777/25415-01/E00-00) 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, and EN 13034 Type 6 for limited chemical splash.
Is the FR503 arc-flash rated?
Yes, under both the European and US standards. It's rated ELIM 6.4 cal/cm² and EBT 6.8 cal/cm² under EN 61482-1-1 (APC 1 under EN 61482-1-2), and ATPV 8.4 cal/cm² (HAF 75.8%) under ASTM F1959/F1959M-12. Check the rating against your site's arc flash risk assessment before use.
Can I wear the FR503 for welding?
Yes, within its rated class. The FR503 is certified to EN ISO 11611 Class 1 (A1+A2), covering less hazardous welding situations than Class 2.
Is the FR503 hi-vis or waterproof?
No. Our certification data doesn't record an EN ISO 20471 high visibility rating or an EN 343 weather rating for the FR503, it's a standard-colour FR work coverall rather than a hi-vis or wet-weather garment.
Does the FR503 have metal-free components?
Yes. It's built with metal-free components throughout, which matters on sites where metal fastenings and buttons could pose an arc flash or spark risk.
How should I wash and care for the FR503 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, so it won't wash out, but retire the coverall if it's visibly damaged or fails a wash care check.
