Sets out requirements for materials, dimensions and performance for polybutylene pipe for hot and cold water applications (metric series), including domestic, industrial and agricultural purposes.

Scope

This Standard specifies materials, dimensions and performance requirements for polybutylene pipe for hot and cold water applications, including domestic, industrial and agricultural purposes.
In the interests of serviceability of the pipe, and irrespective of the calculated minimum wall thickness, a minimum wall thickness of 1.6 mm is intended for pipes joined together with mechanical fittings and 2.2 mm is intended for pipes joined together by fusion.
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 days 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 continuously exposed to direct sunlight.
3 Polybutylene pipe manufactured in accordance with this Standard is intended to be used with fittings complying with AS 5082.2. Joining polybutylene pipe by means of solvent cement is not satisfactory.
4 Type tests specified in Clauses 9.1, 9.4, 9.7, 10.2 and 10.3 are tests performed on pipe, following the crystalline transition time, to assess compliance of finished product with this Standard; however, it may also be convenient for product manufacturers to use those tests for quality control purposes during manufacture.
