Corresponds with the outermost extent of the shoulder joint and generally aligns with the seam joining a‘fit-in’ sleeve to the body of a garment. It can be defined anatomically as the outermost extent of the acromio-clavicular joint (commonly known as the A-C joint), which is derived from the junction of the collar bone (clavicle) and the shoulder blade (scapula).The exact point of measurement (see Figure 1) coincides with the hollow between the shoulder (acromion) and above the long bone of the upper arm (the humerus).
An item of clothing (including personal clothing, garments and clothing accessories such as hats, gloves, sleeves, leggings, wrist protectors, body wraps and blankets, brim and neck protectors such as gaiters or balaclavas for use with helmets or hats) that is designed or made to be used in a way that reduces or minimizes skin exposure and, is manufactured from material which meets the requirements for the minimum UPF rating under this Standard.
The design of clothing for sun protection is an important component in lowering exposure of the body to UVR. Minimal skin coverage afforded by scant clothing design is not recommended. Correct sizing of clothing or loose fitting clothing is also necessary to avoid stretching and afford maximum protection.
Maximum coverage of the skin is recommended when exposed to solar UVR and the more skin covered by material, the better the protection offered. Clothing designs incorporating full length sleeves, collars, crew necklines, long skirt or long trouser legs cover more body surface area, thereby providing a more extensive physical barrier to solar UVR than sleeveless dresses and vests, low necklines, mini-skirts, shorts, bikini tops and briefs.
There are circumstances where a range of materials are used in combination to make up a garment. This Standard allows for such combinations (e.g. use of mesh in underarm of outdoor work shirts). However, parts of the garment covering body parts usually exposed to the sun while outdoors need to meet testing requirements to claim a UPF rating. The lowest UPF rating achieved in testing of multi-component garments, excluding those areas not exposed to sunlight (i.e. armpits), is the rating that shall be used for the garment.AS NZS 4399 pdf free download.
