This standard covers the material, application, and field-procedure requirements for protective exterior coatings consisting of heat-shrinkable cross-linked polyolefin coatings and their application to special sections, connections, and fittings to be used in underground and underwater steel water pipelines. Heat-shrinkable cross-linked polyolefin coatings may be field or shop applied as provided in this standard. This standard covers only heat-shrinkable coatings that consist of a polyolefin backing that has been cross linked by either electron beam or chemical means and coated with a non-cross linked adhesive.
