HIVIS Standards

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 0.2m2 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.
