Specifies requirements for small diameter, low pressure polyethylene pipe suitable for use in the Australian environment at temperatures up to 60 degrees Celsius. It provides for two types according to type classification of extrusion compound in AS 1463 and one pressure class with a maximum working pressure of 0.3 MPa at 20 degrees Celsius. Nominal inside diameter range is 10 to 32 mm. Tests are given in appendices.

This standard specifies requirements for black polyethylene pipe for use in micro-irrigation applications below and above ground.NOTE: Advisory information on alternative methods for determining compliance of a 'lot' with this standard is given in Appendix A.
