Specifies requirements for cross-linked polyethylene pipe for use in water supplies, including domestic, industrial, agricultural and other hot and cold water applications. Pipes complying with this Standard shall not be stored or installed in direct sunlight. While This Standard applies to pipes with or without integral barrier layers, the barrier layer is not considered in the pipe performance requirements.

This Standard specifies requirements for cross-linked polyethylene pipe for use in water supplies, including domestic, industrial, agricultural and other hot and cold water applications. Pipes complying with this Standard shall not be stored or installed in direct sunlight. This Standard applies to pipe with or without integral barrier layers.NOTES:1 Cross-linked polyethylene pipe is intended to be used with fittings complying with AS 2537. Jointing cross-linked polyethylene pipe by means of solvent cement is not satisfactory.2 While this Standard applies to pipes with or without integral barrier layers, the barrier layer is not considered in the pipe performance requirements.
