适用范围：1.1 This standard prescribes a designation system and covers require-ments and the methods of sampling and tests for polypropylene moulding and extrusion materials of nominal density 0·905 g/ml at 27°C and having melt flow indices ranging from 0·25 to 32·0 g/10 min.1.2 This standard is applicable to all propylene homopolymers and to copolymers of propylene containing at least 50 percent ( m/m ) of propylene. It applies to compositions thereof, in the form of powder, granules or pellets, and to propylene plastics unmodified, or modified by colourants, additives, fillers, etc.Note — This standard does not provide engineering data or performance data which may be required to specify materials for particular end-use applications and processes. It is not intended to imply that materials having the same designation give the same performance.
