DIN EN ISO 20028-1:2017-07 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodi

27、es). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and

28、non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are desc

29、ribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).Attention is draw

33、 materials.This first edition of ISO 20028-1 cancels and replaces ISO 7792-1:2012, which has been technically revised to introduce a new designation system.The revised designation system is published under a new ISO number, as many existing documents refer to ISO 7792-1. If the existing ISO 7792-1 w

34、ould be replaced by the new designation system, these documents would refer to the incorrect designation system.In order to give users time to switch from ISO 7792-1 to ISO 20028-1, any designation system according to ISO 7792-1 is to be phased out in 5 to 10 years.A list of all parts in the ISO 200

35、28 series can be found on the ISO website.4 EN ISO 20028-1:2017 (E) DIN EN ISO 20028-1:2017-07 IntroductionISO 7792-1 is complex and does not fit with daily practice anymore. In practice, ISO 1043 and ISO 11469 are, in combination, “improperly” being used as a designation system for, for example, ma

36、rking. The aim of this revision is to simplify the data block system and to connect more to ISO 1043 and ISO 11469, where the first two blocks are used for generic identification and marking of products.5 EN ISO 20028-1:2017 (E) DIN EN ISO 20028-1:2017-07 1 ScopeThis document establishes a system of

37、 designation for thermoplastic polyester (TP) material, which can be used as the basis for specifications. It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT),

38、poly(ethylene naphthalate) (PEN), poly(butylene naphthalates) (PBN) and other TP-types and copolyesters of various compositions for moulding and extrusion.The types of thermoplastic polyester are differentiated from each other by a classification system based on appropriate levels of the designatory

39、 properties:a) viscosity number;b) tensile modulus of elasticity;and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.This designation system is applicable to thermoplastic polyester homopolymers

40、and copolymers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, fillers and other additives. This document does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers covered by ISO 20029.I

41、t is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material. If such additional properties are required, the

42、y are intended to be determined in accordance with the test methods specified in ISO 20028-2, if suitable.In order to designate a thermoplastic polyester material to meet particular specifications, the requirements are to be given in data block 5 (see 3.1).2 Normative referencesThe following documen
