Tests forUV and abrasion resistance are under development and it is theUK commit

3、tees intention that the results be considered in futurerevisions of the standard.There is evidence that UV weakens many man-made fibres.Therefore, users of lanyards conforming to this European Standardare recommended to check with equipment suppliers thatequipment made from textiles is protected fro

4、m the adverse effectsof UV (e.g. polyamide, polyester, polyethylene, polypropylene andaramid). Manufacturers are advised to check with suppliers of textilematerials for the same. Users of textile equipment should alsocarefully and regularly inspect their equipment for signs of abrasion(both external
