Application

This unit describes the skills and knowledge required to install polyvinylchloride (PVC) plastic pressure pipeline components in the field, in the form of UPVC (unplasticised PVC), MPVC (microcellular PVC) or OPVC (oriented PVC).

This unit applies to an experienced technician working alone or as part of a team.

The unit principally refers to the assessment of suitability of materials for specific gas or water pressure applications, preparation for and performance of chemical and mechanical jointing, repairs and service connections, and solving installation problems.

No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
