Australian clothing standard
In July 1996 Australia became the first country to introduce a standard for evaluating and classifying sun protective clothing (AS/NZS 4399:1996 'Sun Protective Clothing-Evaluation and Classification'). The standard uses the term ultraviolet protection factor (UPF) to designate the amount of protection provided by personal clothing and also classify clothing into broad protection categories as shown in the following table.

In Australia garments with UPF ratings less than 15 cannot be labelled as sun protective. Garments with UPF ratings higher than 50 are labelled as UPF 50+. ARPANSA offers a UPF testing service for rating sun protective materials.

Companies can have their materials tested for UPF rating then make UPF labels follow the directions for in AS/NZS 4399. ARPANSA can supply ready made UPF swing tags that are made according to this standard.
