The HV Yellow shade of our modacrylic knit FR-Pique-230 has an Aitex certificate of test to EN ISO 20471, the standard for high-visibility clothing. It passed all seven tests, with colour and luminance measured after 50 domestic washes and after xenon light exposure.
What was tested?
Fabric FR-Pique-230, 60% modacrylic, 38% cotton, 2% antistatic, 230 gsm, colour HV Yellow. Laboratory: Aitex, Spain. Certificate of test 2026EP5324, issued 30 September and 29 October 2026.
What does this mean for you?
- Stays compliant longer. HV Yellow colour and brightness meet EN ISO 20471 after 50 washes, not 5 as before, so polos keep their hi-vis rating much longer in daily use.
- One fabric for several risks. The same knit is certified to EN ISO 11612 (heat and flame), EN 1149-5 (antistatic) and EN IEC 61482-1-1 (arc, ATPV 7.5 cal/cm²), so one garment covers hi-vis, flame, static and arc.
- Comfortable all day. Water vapour resistance is within the EN ISO 20471 limit of 5 m²·Pa/W, so the pique stays breathable as a polo or T-shirt under an FR jacket.
- Easier garment certification. You can submit our Aitex certificate of test with your garment’s EN ISO 20471 technical file.
What is new compared to 2021?
The earlier certificate covered 5 washes. Colour and luminance are now measured after 50 domestic washes and after xenon light exposure.
How should the fabric be cared for?
EN ISO 6330, programme 4N, tumble drying type A1.
Where is the certificate?
The Aitex certificate of test 2026EP5324 is on our site. It is a test summary, not a product certification. The protective properties of the fabric are listed in the technical datasheet.
