AS NZS 2604:2021 pdf free download – 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.

(d) Clear and appropriate directions for the use of the product in order to achieve the labelled claims shall appear on the container.
(e) With the instruction to “apply generously to the skin 20 minutes before skin exposure. then reapply frequently, and after swimming, sweating or towelling”; or words to this effect.

6.2.2 Optional labelling
62.2.1 General
Provided the relevant requerements in C1au.e are satisfied, primary sunscreen products may also be labelled with the following:
(a) Category description (see Clause 6.2.2.2).
(b) The words “water resistant” (see CIatie6Z23).
6.2.2.2 Category description
Where a category description is to be given, the wording given in Table 1 according to the labelled SPF shall be used.
6.2.2.3 Water resistant primary sunscreen products
Water resistant primary sunscreen products may be labelled as “water resistant” provided that the words “water resistant” appear on the main label of the container in letters no larger than those used for the labelled SPF. Any claim of water resistance shall be qualified by a statement of the time for which the water resistance has been tested (in accordance with Appendi.U). LI to the maximum time claimable In accordance with Table 2.
6.3 Secondary sunscreen products
6.3.1 Mandatory labelling
Secondary sunscreen products shall be labelled as follows:
(a) The labelled SPF shall be marked on the container In durable and legible characters and In such a colour or colours as to afford a distinct contrast to the background colour.
(b) Numerical labelled SPFs greater than 50+ are not permitted. The terms 50+ or “50 plus” shall only be used on products with a tested SPF of 60 or greater. The labelled SPF shall be prefixed only by the expressions “sun protection factor” or “SPF.
(c) Clear and appropriate directions for the use of the product In order to achieve the labelled claims shall appear on the container.
