Classification of Garments
The garments specified in this standard are classified into one of the following: · Class D - a garment designed for outdoor daytime use only, comprising
fluorescent or other non-retroreflective high visibility material. · Class N - a garment designed for night-time use only, comprising
retroreflective elements on an unspecified background. · 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 materials that meet
the requirements of Class F in AS/NZS 1906.4. Colours are normally red-orange
or lime yellow.
· Non-fluorescent materials. Where safety requirements require
a garment to be made from a material which is not capable of taking a fluorescent
pigment e.g. certain natural fibres, a non-fluorescent colour as specified in
AS/NZS 1906.4 may be used in lieu.
· Garment design - Class D garments shall comprise a garment or
combinations of garments of any desired type or style which as a minimum, encircles
the upper torso. There shall be a minimum visible area of 0.4m2 of material
meeting the requirements of either fluorescent or non-fluorescent materials.
· Retroreflective Materials - Not required for this class.

when viewed under retroreflected light, such as by drivers of vehicles using
headlight illumination. The colour of the background is not specified.
· Retroreflective materials used on Class N garments shall meet the requirements
for Class R material specified in AS/NZS 1906.4. Material strips must not be
less than 50mm wide to at least the minimum patterns specified. Retroreflective
patches, words, symbols, and the like shall be regarded as additional to, and
not replacing, the specified patterns of retroreflective strips.
· Garment design - Class N garments shall comprise a garment or combinations
of garments of any desired type or style which as a minimum, encircles the upper
