Sun protective clothing - Evaluation and classification

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 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.
