GB/T 12670-2008 Polypropylene (PP) resin 1 Scope This standard specifies the classification and designation, requirements, test methods, inspection rules, marking, packaging, transportation and storage of polypropylene (PP) resin (PP resin). This Standard applies to particulate propylene homopolymer (PP-H), propylene impact copolymer (PP-B) or propylene random copolymer (PP-R) containing additives prepared by polymerization of propylene or propylene/ethylene under the action of catalysts. This Standard is not applicable to colored, filled, modified and mixed PP resin and masterbatch materials. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this standard. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition applies.
