1906.4.2010
This standard explains the use of hi-visibility fabrics and
retroreflective materials. It specifies the chromaticity levels to
which fabrics need to be dyed in terms of performance and atmospheric
pressures in order to comply safety standards. Natural fibre garments
have a lower chromaticity level due to the nature of the fabric.
However, only when a polyester garment is deemed a risk to the wearer in
certain applications, should cotton or wool be worn in its place.
CLASS F = DAYTIME FLUORESCENT
CLASS R = RETROREFLECTIVE MATERIAL
CLASS RF = RETROREFLECTIVE AND FLUORESCENT
CLASS NF = HIGH DAYTIME VISIBILITY NON FLUORESCENT
4602.1.2011
This standard refers to how a garment is constructed using fabrics
compliant to 1906.4 above.
There has to be over 0.2m squared of unbroken fluoro fabric on both
the front and back of a garment in the upper torso (not including the
sleeves). The fluoro must not be broken with non fluoro fabric within the
0.2m2 area on both the front and back from the top of the shoulders
to the waist and MUST encircle the body up to that measurement, so no
full side panels up to armpit level are permitted. This standard also
explains the position of the retroreflective tapes on the garment and the
width and quantity used. These tapes should not detract from the 0.2m2
measurement required.
CLASS D = DAYTIME USE
CLASS N = NIGHT TIME USE USING RETROREFLECTIVE MATERIAL
CLASS D/N = DAY/NIGHT USE
4399
This standard refers to the capability of a fabric to protect skin
against solar ultra violet radiation (known as UPF = ultra violet
protection factor). This standard is an additional bonus to the garment
rather than an essential requirement for hi-visibility standards but
often specified from specific industry users.
