This Standard sets out requirements for determining the rated ultraviolet protection factor of sun protective textiles, garments and other items of personal apparel (such as hats) which are worn in close proximity to the skin. It also specifies appropriate detailed labelling requirements. It does not cover sunscreen products for topical application to the human skin, fabrics for architectural or horticultural use such as shadecloth, or sunglasses. It does not cover items which offer protection at a distance from the skin, such as umbrellas or shade structures, or protection from ultraviolet radiation sources other than the sun.
