Joint materials by fusion processes on Utilities Network Construction, above 180mm diameter LEGACY
Overview
This national occupational standard defines the competence required to joint materials by fusion on utilities above 180mm diameter, using non-automatic and automatic machines, on parent materials with the same SDR rating and polymer type. The jointing process may be carried out in all weather conditions in accordance with industry standards and specifications.
