The work of pr
19、eparing 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 nongovernmental, in
20、 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 described in the ISO/IEC
21、 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 drawn to the possibility th
22、at some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent d
23、eclarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to conformit
24、y assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermopla
25、stic materials.This first edition of ISO 20029-1 cancels and replaces ISO 14910-1:2013, 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 149101. If the existing ISO 149
26、101 would 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 149101 to ISO 200291, any designation system according to ISO 149101 is to be phased out in 5 to 10 years.A list of all parts in the ISO
27、 20029 series can be found on the ISO website.iv ISO 2017 All rights reservedBS EN ISO 200291:2018ISO 20029-1:2017(E)IntroductionISO 14910-1:2013 is complex and does not fit with daily practice anymore. In practice, ISO 18064 and ISO 11469 are, in combination, “improperly” being used as a designatio
28、n system for, e.g. marking. The aim of this document is to simplify the data block system and to connect more to ISO 18064 and ISO 11469, where the first two blocks are used for generic identification and marking of products.

30、sed as the basis for specifications.The types of thermoplastic polyester/ester and polyether/ester elastomer are differentiated from each other by a classification system based on appropriate levels of the designatory properties:a) hardness;b) melting temperature;c) tensile/flexural modulus of elast
31、icity;and on information about the intended application and/or method of processing, important properties, additives, colour, fillers and reinforcing materials.This document is applicable to all thermoplastic polyester/ester and polyether/ester elastomers. It applies to materials ready for normal us
32、e in the form of powder, granules or pellets, unmodified or modified by colourants, fillers or other additives.It 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 pr
33、ocessing conditions which may be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20029-2, if suitable.In order to designate a thermoplastic polyester/ester or polyether/ester elastomer
34、 to meet particular specifications, the requirements are given in data block 5 (see 4.1).2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

39、eading “Thermoplastics”, and an identity block comprising the International Standard number and an individualitem block. For unambiguous designation, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: Identification of the plastic by its
40、 abbreviated term (TPC), in accordance with ISO 18064, and information about the composition of the polymer (see 4.2). Data block 2: fillers or reinforcing materials and their nominal content; flame retardant; optionally recyclate and its content (see 4.3). Data block 3: Position 1: Intended applica
41、tion and/or method of processing (see 4.4). Positions 2 to 8: Important properties, additives and supplementary information (see 4.4). Data block 4: Designatory properties (see 4.5). Data block 5: For the purpose of specifications, a fifth data block contains appropriate information (see 4.6).The fi
42、rst character of the individual item block shall be a hyphen. The five data blocks shall be separated from each other by a comma. If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,). Terminal commas may be omitted.NOTE Data blocks 1 and 2 toge
43、ther form the part marking symbol.4.2 Data block 1In this data block, after the hyphen, the thermoplastic elastomer is identified by its abbreviated term in accordance with ISO 18064 and, after a space, a symbol indicating the composition as specified in Table 1.Table 1 Symbols indicating the chemic

For copolyester thermoplastic elastomers, the prefix TP is followed by the letter C.Copolyester thermoplastic elastomers consist of a block copolymer of alternat
46、ing hard segments and soft segments, the chemical linkages in the main chain being ester and/or ether. The “TPC” group is subcategorized into groups according to the linkages in the soft blocks (see Annex A).4.3 Data block 2In this data block, the type of filler and/or reinforcing material is repres
47、ented by a single code-letter in position 1 and its physical form by a second code-letter in position 2, the code-letters being as specified in Table 2. Subsequently (without a space), the actual content may be given by a two-figure code-number in positions 3 and 4.Mixtures of materials and/or forms
48、 may be indicated by combining the relevant codes using the sign “+” and placing the whole between parentheses followed by the total filler content. For example, a mixture of 25 % (by mass) of glass fibre (GF) and 10 % (by mass) of mineral powder (MD) would be indicated by (GF25+MD10) or (GF+MD)35.T
