This test method describes a reliable methodology for determining the peel strength of polyolefin-based multilayer pipeline coating systems, generally for coating thickness less than 12 mm (0.47 in). This standard provides a method to measure the peel strength of polyolefin-based multilayer coating systems, such as 2-layer polyethylene coating (2LPE), 3-layer polyethylene (3LPE), 3-layer polypropylene (3LPP), and heat shrink sleeve (HSS) field joint coating. It provides essential information on the quality of the applied coating. This is particularly important for field-applied coatings, of which the application process is significantly impacted by the environmental conditions and the skill set of the field applicators.
