Field-applied external coatings for steel pipeline systems

1.1
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
This Standard covers the following coating systems: 

a) System FC1: liquid-applied or fusion bond epoxy (FBE) with a glass transition temperature of up to 115 °C; 

b) System FC2: liquid-applied or FBE with a glass transition temperature of 115 °C or greater; 

c) System FC3: liquid-applied 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
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 (nonmandatory) to define their application.
