This Standard sets out procedures for determining the performance of sunscreen products in terms of their mean protection factors. It includes test methods for both broad spectrum and water resistant sunscreen products. This Standard also specifies appropriate detailed labelling requirements to be applied in conjunction with relevant legislation.

This Standard applies to sunscreen products represented as being suitable for topical use to protect human skin from the adverse effects of solar ultraviolet (UV) rays. It applies to both primary and secondary sunscreen products as defined.

As this Standard addresses protection against solar radiation incident upon the surface of the Earth, protection against UVC does not fall within its scope, as it is filtered out by the earth's atmosphere.

Reference to ISO 24444 is required for the determination of the sun protection factor (SPF).

Reference to ISO 24443 is required for the determination of broad spectrum performance.

NOTE: A sample questionnaire for test subjects is given in Appendix E.
