    Abstract - (Show below) - (Hide below)

    Specifies materials, dimensions and performance requirements for polybutylene pipe for hot and cold water plumbing applications, including domestic, industrial and agricultural purposes.

    Scope - (Show below) - (Hide below)

    This Standard specifies materials, dimensions and performance requirements for polybutylene pipe for hot and cold water plumbing applications, including domestic, industrial and agricultural purposes.
    In the interests of serviceability of the pipe, and irrespective of the calculated minimum wall thickness, this Standard does not apply to a wall thickness of less than 1.6 mm. The Standard applies to pipes of pressure class PN16 up to 28 mm nominal outside diameter.

    NOTES:
    1 Polybutylene undergoes a crystalline transition after it has cooled from the molten state. As a consequence, pipe manufactured to this Standard will not have achieved its full strength until 10 d after the date of manufacture, i.e. the date stamped on the pipe. Precautions should be taken to ensure that pipe is not released from the manufacturer’s control prematurely and installed before gaining full strength.
    2 Polybutylene pipe manufactured in accordance with this Standard is only considered suitable for use in situations exposed to indirect sunlight if it is stabilized against ultraviolet degradation. The only allowable method of stabilization is by the addition of 2.25 (0.25% of carbon black. Polybutylene pipe should never be used in situations where pipe is exposed to direct sunlight.
    3 Polybutylene pipe manufactured in accordance with this Standard is intended to be used with fittings complying with AS/NZS 2642.3.
