IMPORTANT LIMITATIONS OF USE

Under no circumstances should Class Day (D) garments be worn for visibility purposes at night. Any markings, attachments, screen prints or other alterations, accessories or coverings not incorporated into the original product may not only void the garment’s compliance with the appropriate standard, they may also put the user at risk by reducing the high-visibility performance of the garment. The high-visibility properties offered by Hard Yakka Hi Visibility garments may be lessened due to normal wear over time or if the fabric is stretched. Hard Yakka Hi-Visibility garments using natural fibres have been tested and comply to Australian Standards AS/NZS 4602.1:2011 High-Visibility Safety Garments in dry conditions. Wet conditions may alter the compliance of these fabrics to the standard and appropriate care should be taken.

According to the Australian Standard, materials classified as high-visibility for daytime use must be manufactured from a durable fabric of woven or knitted cotton or equivalent man-made fibre that contains a fluorescent pigment or other high-visibility dye, or to which a fluorescent plastic coating has been applied. These materials are subjected to the following tests and must meet or exceed specified minimum requirements for:

  • Daylight colour and luminance factor
  • Colourfastness to light
  • Colourfastness to washing
  • Colourfastness to perspiration
  • Colour retention testing

In some cases, for safety reasons, a garment must be made from a natural fibre incapable of retaining a fluorescent colour. In these instances, the material is tested for luminance for non-fluorescent materials. Alternatively, man-made fibres are generally capable of retaining a fluorescent colour and are therefore tested for luminance for fluorescent materials. The fabrics used in the manufacture of Hard Yakka Hi-Visibility workwear are tested and must meet or exceed specified minimum requirements for:

  • Chromaticity
  • Luminance for fluorescent materials
  • Luminance for non-fluorescent materials
