Certified protection, built to last

Certified flame & heat protection

Meets EN ISO 11612 (A1, B1, C1, F1) for heat and flame - the fabric resists ignition and self-extinguishes if it catches alight.

Anti-static and arc-flash certified

Certified to EN 1149 for anti-static use and IEC 61482 for arc-flash exposure, alongside its flame protection.

Flame resistance built in for life

FR properties are inherent to the fibre, not a topical treatment, so they will not wash out or fade with repeated laundering.

Quick visual identification

An external standards label on the sleeve shows protection levels at a glance for on-site compliance checks.

Frequently asked questions

What certifications does the FR11 carry?

It meets EN ISO 11612 (A1, B1, C1, F1) for heat and flame protection, EN 1149 for anti-static performance, and IEC 61482 for arc-flash exposure.

Can this be worn where there's an arc-flash risk?

Yes - it's independently rated to IEC 61482 for arc-flash exposure, in addition to its flame and heat certification.

Does washing affect the flame-resistant properties?

No. The FR performance is built into the fibre itself rather than applied as a surface treatment, so it holds up through normal laundering rather than fading after a few washes.

Is it safe to wear in ATEX or other static-sensitive zones?

Yes - the fabric is certified anti-static to EN 1149, which is why it's specified for zoned sites alongside its flame protection.

What sizes and colourways does the FR11 come in?

Unisex sizing from XS to 5XL, in navy, black, grey marl and sand.

Can we get a company logo added?

Yes - embroidery and logo printing are both available as options, so it can be branded for a crew or site.

Is it meant to be worn alone or as a base layer?

It works either way - on its own in warmer conditions, or as a base layer under FR jackets, coveralls or hi-vis outerwear when extra protection is needed.
