Australian Standards for High Visibility Safety Garments
The Australian Standard AS/NZS4602.1:2011 specifies the visual requirement for high visibility safety garments for occupational wear by people who may be exposed to hazard from moving traffic, moving plant or equipment in high risk situations.
Classification of garments
The garments specified in the Australian Standard AS/NZS4602.1:2011 are classified as follows:
Class D – a garment designed for daytime use only. Class D garments are intended to provide the wearer with high visibility under daylight viewing conditions and generally not effective when viewed under artificial light.
Class N – a garment designed for night-time use only.
Class D/N – a garment designed for both day and night use, comprising retroreflective elements on a fluorescent or other non-retroreflective high visibility background material.
Class D Garments - These garments are intended to provide the wearer with high visibility under daylight viewing conditions in outdoor situations. Fluorescent materials shall be made from background material meeting the requirements of AS/NZS 1906.4:2010 for class F. Colours for normal purposes are specified as either red?orange or yellow Non-fluorescent materials: Where safety requirements in a particular industry require a garment to be made from a background material that is not capable of taking a fluorescent pigment e.g. certain natural fibres, a nonfluorescent colour Class NF as specified in AS/ NZS 1906.4:2010 may be used in lieu.
Garment design: A Class D garment shall comprise a garment or combination of garments of any desired type or style which, as a minimum, encircles the upper torso. There shall be a minimum visible area of background material determined to be not less than 0.2 m² on each of the front and the back of the garment meeting the requirements of either fluorescent or nonfluorescent materials.
Class N Garments
These garments are intended to provide the wearer with high visibility at night when viewed under retroreflected light, such as by drivers of vehicles using headlight illumination. The colour of background material is not specified.
Retroreflective materials: Retroreflective material used on Class N garments shall meet the requirements specified in AS/NZS 1906.4 for Class R or class RF material. Material shall be applied to garments in strips not less than 50mm wide to at least the minimum pattern requirements as per style #1 (H pattern), style #2 (X pattern) and style #3 (hoop pattern). Retroreflective patches, words, symbols and the like shall be regarded as additional to, and not replacing, the specified patterns of retroreflective strips.
Garment Design: A Class N garment shall comprise a garment or combination of garments of any desired type or style, which as a minimum, encircles the entire upper torso down to waist level. Strips of retroreflective material shall be applied as per style #1 (H pattern), style #2 (X pattern) and style #3 (hoop pattern).
Class D/N Garment
Garments in this category are intended to provide the wearer with high visibility under both daylight viewing and night time viewing under retroreflected light.
Garment Design: As a minimum, a Class D/N garment shall consist of all the requirements of both a Class D and N garment.
