18、 ISO 14910-1:2013ISO 14910-1:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body in
19、terested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechni
20、cal Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the t
21、echnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

22、O shall not be held responsible for identifying any or all such patent rights.ISO 14910-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.This second edition cancels and replaces the first edition (ISO 14910-1:1997), which has been technically revi

25、tion for thermoplastic polyester/ester and polyether/ester elastomers, which may be used 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 designato
26、ry propertiesa) hardness;b) melting temperature;c) tensile/flexural modulus of elasticity;and on information about the intended application and/or method of processing, important properties, additives, colour, fillers and reinforcing materials.This part of ISO 14910 is applicable to all thermoplasti
27、c polyester/ester and polyether/ester elastomers. It applies to materials ready for normal use 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
28、 performance. This part of ISO 14910 does not provide engineering data, performance data or data on processing conditions which might 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 ac
29、cordance with the test methods specified in ISO 14910-2, if suitable.In order to specify a thermoplastic polyester/ester or polyether/ester elastomer for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1 and 3.6).2 Normative

33、f an optional description block, reading “Thermoplastics”, and an identity block comprising the International Standard number and an individual-item block. For unambiguous designation, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: I
34、dentification of the plastic by its abbreviated term (TPC), in accordance with ISO 18064, and information on the alternating hard and soft segments in the main chain (see 3.2). Data block 2: Position 1: Intended application and/or method of processing (see 3.3). Positions 2 to 8: Important propertie
35、s, additives and supplementary information (see 3.3). Data block 3: Designatory properties (see 3.4). Data block 4: Fillers or reinforcing materials and their nominal content (see 3.5). Data block 5: For the purpose of specifications, a fifth data block containing additional informa-tion may be used
36、 (see 3.6). The kind of information and the code-letters used are not the subject of this part of ISO 14910.The first 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 do
37、ubling the separation sign, i.e. by two commas (,).Terminal commas may be omitted.3.2 Data block 1In this data block, after the hyphen, the thermoplastic elastomer is identified as follows.The prefix TP is followed by a letter representing the category of the thermoplastic elastomer, as given in ISO
38、 18064. For copolyester thermoplastic elastomers, the prefix TP is followed by the letter C.2 ISO 2013 All rights reservedBS EN ISO 14910-1:2013ISO 14910-1:2013(E)Copolyester thermoplastic elastomers consist of a block copolymer of alternating hard segments and soft segments, the chemical linkages i

44、, the melting temperature by a two-figure code-number (see 3.4.3) and the tensile/flexural modulus of elasticity by a three-figure code-number (see 3.4.4). The code-numbers are separated from each other by hyphens.If a property value falls on or near a range limit, the manufacturer shall state which
45、 range will designate the material. If subsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, the designation is not affected.3.4.2 HardnessThe hardness shall be determined in accordance with ISO 14910-2.The possible values of the hardness are
46、divided into 11 ranges, each represented by a two-figure code-number as specified in Table 2.Table 2 Code-numbers used for hardness in data block 3Code-numberRange of hardness (Shore D)30 3235 32 but 3740 37 but 4245 42 but 4750 47 but 5255 52 but 5760 57 but 6265 62 but 6770 67 but 7275 72 but 7780
47、 77NOTE The hardness of thermoplastic elastomers is measured in Shore A and Shore D units. Shore hardness is a measure of the resistance of a material to penetration by an indenter under a defined spring force. It is determined as a number from 0 to 100 on the Shore A or Shore D scale. The higher th
48、e number, the higher the hardness of the material. The Shore A scale is used for very flexible types of elastomer and the Shore D scale for less flexible and rigid types. The Shore A and Shore D scales overlap. For the designation of thermoplastic polyester/ether and polyether/ester elastomers, the
49、Shore D scale is used as this scale covers the whole range of hardnesses encountered and is able to discriminate between very flexible, medium flexible and rigid materials.3.4.3 Melting temperatureThe melting temperature shall be determined in accordance with ISO 14910-2.The possible values of the melting temperature are divided into 10 ranges, each represented by a two-figure code number as specified in Table 3.4 ISO 2013 All rights reservedBS EN ISO 14910-1:2013ISO 14910-1:2013(E)Table 3 Code-numbers
