This Standard sets out procedures for determining the performance of materials and items of clothing that are worn in close proximity to the skin to provide protection against solar ultraviolet radiation (UVR). The sun protective capability of materials and clothing is described in terms of their ultraviolet protection factor (UPF), which is based on an objective, reproducible test conducted on the material.This information is provided to the consumer in the form of a labelling scheme.
This Standard applies to all materials and items of clothing seeking to claim a UPF rating. All such clothing needs to be designed in a manner that supports the concept of minimal skin exposure. This Standard specifies the minimum amount of body coverage by an item of clothing in order to be allowed to make a UPF claim.
