The polyester may be a homopolymer, a copolymer or a mixture of the two.It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.1.4     It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 7391 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing.If such additional properties are required, they shall be determined in accordance with the test methods specified in Part 2 of this International Standard, if suitable.1.5     In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).【中国标准分类号】: G32【国际标准分类号】: 83_080_20【页数】: 7P;A4【正文语种】: 英语
