Canadian Standards Association External Polyethylene Coating for Pipe,Z245.21-02,External Polyethylene Coating,for Pipe,1. Scope,1.1,This Standard covers the qualification, application, inspection, testing, handling, and storage of materials,required for plant-applied polyethylene coating applied externally to pipe, whereby an adhesive is,interposed between a bare or epoxy-primed pipe and the polyethylene. The coated pipe is primarily,intended for buried or submerged service for oil or gas pipeline systems.,1.2,This Standard covers the following coating systems：,(a) System A1: a coating that consists of an adhesive and a polyethylene outer sheath；,(b) System A2： a coating that consists of an adhesive and a polyethylene outer sheath that has more,stringent peel adhesion requirements than those for System Al (see Table 1)；,(c) System Bl: a coating that consists of a liquid or powdered epoxy primer, a polymeric adhesive, and,a polyethylene outer sheath； and,(d) System B2: a coating that consists of a powdered epoxy primer, a powdered copolymer adhesive,and a powdered polyethylene outer layer.,1.3,In CSA Standards, ^shalT' 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 i$ advised but not required; and "may" i$ 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. Legends to equations and figures are considered requirements.,2. Reference Publications,This Standard refers to the following publications, and where such references are made, it shall be to the,editions listed below, unless the user finds it more appropriate to use newer or amended editions of such,publications.,CSA Standards,CAN/CSA-ISO 9000-1 -94 (R2000),Quality Management and Quality Assurance Standards ——Part 1： Guidelines for Selection and Use,CAN/CSA-ISO 9000-2-98,Quality Management and Quality Assurance Standards — Part 2: Generic Guidelines for the Application of,ISO 9001, ISO 9002 and ISO 9003,November 2002 37,Copyriqhi コv the： CSA,.Thu Mcr 25, 11:09:90 2001,Z245.21-02 .
