AS NZS 2604:2021 Sunscreen products – -Evaluation and classification.
This document 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 document also specifies appropriate detailed labelling requirements to be applied in conjunction with relevant legislation.
This document applies to sunscreen products represented as being suitable for topical use to protect human skin from the adverse effects of solar UV rays. It applies to both primary and secondary sunscreen products as defined.
As this document 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 24443 is required for the determination of broad spectrum performance.
Reference to ISO 24444 is required for the determination of the sun protection factor (SPF).
Reference to ISO 16217 is required for the determination of water resistance.
