3 Definitions The following definitions shall apply in this Standard: Background material — bright-coloured or fluorescent material intended to be highly conspicuous, but not intended to provide retroreflective performance. Note: Background material can cover the whole garment or a portion of the garment. Bright-coloured material — textile material that emits most of the optical radiation absorbed in a specific colour range. Colour contrast — materials having a distinct colour difference from each other. Combined-performance retroreflective material — material that is both retroreflective and fluorescent across its full width. Conspicuity — characteristics of an object that determine the likelihood that it will come to the attention of an observer, especially in a complex environment that has competing objects. Emergency first responder — an emergency professional who is assigned to be first on the scene of a disaster, incident, or threat to public security; an individual, who, in the early stages of an incident, is responsible for the protection and preservation of life, property, evidence, and the environment. Note: Examples of emergency first responders are: police officers, firefighters, or emergency medical technicians who arrive at the scene of a disaster, incident, or life-threatening situation. Flame resistance — the property of a material whereby flaming combustion is prevented, terminated, or inhibited following the application of a flaming or non-flaming source of ignition, with subsequent removal of the ignition source. Note: “Flame retardant” or “fire retardant” are sometimes used as synonyms for “flame resistance”. They are not synonyms. Flame retardant is a chemical used to treat a material to make it flame resistant. Flame-resistant (FR) applications — applications used wherever workers could be exposed to an ignition source, flash fire, or the thermal effects of an electrical arc. Note: FR requirements set by ASTM F1506, ASTM F1891, NFPA 2112, or CAN/CGSB-155.20 should apply as appropriate.
5 Requirements for background and combined-performance retroreflective materials 5.1 Colour of background and combined-performance materials 5.1.1 For background materials, the chromaticity shall lie within one of the areas defined in Table 2 or 3, and the luminance factor shall exceed the corresponding minimums in Table 2 or 3. 5.1.2 For combined-performance retroreflective materials, the chromaticity shall lie within one of the areas defined in Table 2, and the luminance factor shall exceed the corresponding minimum in Table 2. 5.2 Colourfastness properties for background materials Δ 5.2.1 Colourfastness to light (Xenon) The colours after light exposure shall be determined in accordance with ISO 105-B02, Method 1 or with AATCC 16.3, Test Option 3. If AATCC 16.3 is used, exposing the materials to 40 AATCC Fading Units (170 kJ/m 2 @ 420 nm), the results shall be within the specifications defined in Clause 5.1. 5.2.2 Colourfastness to crocking The colourfastness to crocking shall be determined in accordance with CAN/CGSB-4.2 No. 22 or AATCC 8. The colourfastness to crocking, both wet and dry, shall be equal to or better than Grade 3.0 as determined by the Grey scale for colour change. 5.2.3 Colourfastness to perspiration The colourfastness to perspiration shall be determined in accordance with CAN/CGSB-4.2 No. 23 or AATCC 15. The colourfastness to perspiration shall be equal to or better than Grade 3.0 as determined by the Grey scale for colour change and equal to or better than Grade 3.0 by the Grey scale for staining. 5.2.4 Colourfastness properties related to care labeling The performance requirements and test methods shall be as specified in Table 4.
5.3.2 The dimensional change of background material shall not exceed ± 4% in length and ± 4% in width for woven fabrics. 5.3.3 The dimensional change of background material shall not exceed ± 8% in length and ± 8% in width for knit fabrics. 5.3.4 The specimen material shall be prepared in accordance with ASTM D1776. 5.4 Mechanical properties of background materials 5.4.1 Bursting strength of knitted and other nonwoven materials The minimum bursting strength shall be 133 N. Bursting strength shall be tested in accordance with CAN/CGSB-4.2 No. 11.2 or ASTM D3787. 5.4.2 Tear resistance of woven materials (uncoated, coated, or laminated) Background materials for HVSA shall have a minimum tear resistance of 13 N in both directions. These materials shall be tested in accordance with CAN/CGSB-4.2 No. 12.3/ISO 13937 or ASTM D1424. 5.5 Performance under wet conditions 5.5.1 Water repellency Where the manufacturer claims that HVSA is water-repellent, background material shall be tested in accordance with CAN/CGSB-4.2 No. 26.2/ISO 4920 or AATCC 22 with an original requirement of 90 and a requirement of 70 after five laundering cycles (see Clause 7.4.6.2 for the laundering requirements).CSA Z96-15 pdf download.
