Striping and jacket compounds shall contain antioxidants, either singly or in combination,such that when determined in accordance with ISO 1 1357-6 using oxygen, the oxidation induction time shall be not less than 40 minutes at a test temperature of 200°C or a demonstrated equivalent time at a higher temperature.
Antioxidants, ultraviolet light stabilizers and pigments shall be evenly dispersed in the striping or jacket compounds.
When striping or jacket compounds containing carbon black or other pigments are tested in accordance with AS/NZS 1462.28, the rating of appearance shall be not worse than Micrograph B in Annex B of AS/NZS 1462.28, and the arithmetic average of the maximum sizes of pigment agglomerations or foreign bodies shall not exceed 60 um (corresponding to Grade 3 of AS/NZS 1462.28).
NOTE: Because the dispersion of antioxidants and ultraviolet light stabilizers is difficult to assess, it is assumed that if the pigment is evenly dispersed, the other components will also be evenly dispersed.
The weathering resistance test shall apply to all coloured striping and jacket compounds with less than 0.2% by mass of HALS. The weathering resistance, including resistance to ultraviolet light radiation, determined in accordance with AS/NZS 1462.26 on samples exposed to at least 3.5 GJ/m2, shall be such that the mean elongation at break is 350%.
NOTE: The intent of the weathering test is to provide assurance of resistance to weathering encountered during storage and transport of pipes. The test does not provide similar assurance for installations exposed to the elements long term. Data regarding typical incident energy at various sites around Australia can be obtained from the Bureau of Meteorology.
Pipes that are not intended for fuel gas application shall not be visibly coloured yellow in whole or in part. There are separate colour requirements for pipes supplied into Australia or New Zealand.
Series 1 pipes shall be black, blue, yellow, or cream. For potable water, Series 1 pipes shall be blue, or black with blue stripes or jacket. For pressure sewers, Series 1 pipes shall be cream, or black with cream stripes or jacket.AS NZS 4130 pdf free download.
