It supersedes the previous editions published in 2022, 2018 and 2014. This Standard covers the requirements for external coatings for buried or submerged piping as specified by CSA Z662. The following are the major changes to this edition: a) added a new definition for the term "demonstrate"; b) revised the requirements for the MQAP; c) revised the inspector competency requirements; d) revised the peel adhesion test requirements; e) revised the maximum rated service temperature for Systems FC1, FC2, and FC3 in Table 1; f) updated the manufacturer qualification coating test requirements and acceptance criteria for System FC7 in Table 5; g) revised the holiday inspection test method in Tables 6 and 7; and h) revised the holiday inspection requirements for existing coating in Annex A. This Standard was prepared by the Subcommittee on Coatings, under the jurisdiction of the Technical Committee on Petroleum and Natural Gas Industry Pipeline Systems and Materials and the Strategic Steering Committee on Liquid and Gaseous Energy Systems, and has been formally approved by the Technical Committee. Scope 1.1 General This Standard covers the qualification, application, inspection, testing, handling, and storage of materials required for coatings applied externally to steel piping in the field or a shop. Coated piping addressed by this Standard is intended primarily for buried or submerged service in oil or gas pipeline systems. 1.2 Coating systems This Standard covers the following coating systems: a) System FC1: liquid-applied epoxy or fusion bond epoxy (FBE) with a glass transition temperature of 115 °C or less; b) System FC2: liquid-applied epoxy or FBE with a glass transition temperature greater than 115 °C; c) System FC3: liquid-applied epoxy or FBE intended for abrasion service; d) System FC4: adhesive and a polymeric backing (e.g., tape, heat shrinkable sleeve); e) System FC5: epoxy primer, adhesive, and a polymeric backing (e.g., tape, heat shrinkable sleeve); f) System FC6: anti-corrosion coating, if applicable [see Items a), b), d), and e)], polyurethane foam insulation, and a polymeric backing with or without adhesive (e.g., tape, heat shrinkable sleeve); and g) System FC7: fibre-reinforced petrolatum, paraffin-filled, or visco-elastic systems. 1.3 Terminology In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
