9、dization) 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 interested in a subject for which a technical committee has been established has the right to
10、 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used
11、 to develop this document and those intended for its further maintenance are described 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
12、 the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that 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

17、nd basis for specifications1 ScopeThis part of ISO 16365 establishes a system of designation for thermoplastic polyurethane elastomers, which is based on ISO 1043 (all parts) and ISO 11469.The designation system may be used as the basis for specifications.The designation system is applicable to all
18、thermoplastic polyurethane 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, etc.The types of thermoplastic polyurethane are differentiated from each other by a classification system
19、based on appropriate levels of the designatory properties:a) hardness;b) tensile modulus of elasticity (optional);and on information about the alternating hard and soft segments in the main chain, the intended application and/or method of processing, important properties, additives, colour, fillers,
20、 and reinforcing materials.It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 16365 does not provide engineering data, performance data, or data on processing conditions which may be required to specify a material for a part
21、icular application and/or method of processing. If such additional properties are required, it is intended that they be determined in accordance with the test methods specified in ISO 16365-2, if suitable.In order to specify a thermoplastic elastomer for a particular application or reproducible proc
22、essing, additional requirements are intented to be given in data block 5 (see 3.1 and 3.6).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

26、national Standard BlockIndividual Item BlockData Block 1Data Block 2Data Block 3Data Block 4Data Block 5Figure 1 Data block designation systemThe designation consists of an optional description block, reading “Thermoplastics”, and an identity block comprising the International Standard number and an
27、 individual item block. For unambiguous designation, the individual item block is subdivided into five data blocks comprising the following information. Data block 1: Identification of the thermoplastic polyurethane by its abbreviated symbol (TPU), in accordance with ISO 18064, and optional informat
28、ion on the alternating hard and soft segments in the main chain (see 3.2). Data block 2: Fillers or reinforcing materials including summarized nominal content (3.3): important properties, modifier, and flame retardant (3.3); declaration of recyclate: R followed by a number representing the percentag
29、e by mass of recyclate (3.3). Data block 3: Application and processing: Position 1: method of processing (3.4); Positions 2 and further: additives, supplementary information and other characteristics (3.4). Data block 4: Designatory properties (3.5): hardness; modulus. Data block 5: For the purpose
30、of specifications, a fifth data block containing additional information may be used (see 3.6). The kind of information and the code-letters used are not the subject of this part of ISO 16365.The first character of the individual item block shall be a hyphen.The five data blocks shall be separated fr
31、om 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.2 ISO 2014 All rights reservedBS ISO 16365-1:2014ISO 16365-1:2014(E)For part marking the first two data blocks of the designation are u

33、e hardness of thermoplastic elastomers is measured in Shore A and Shore D according to ISO 868. Shore hardness is a measure of the resistance of a material to the penetration of a needle under a defined spring force. It is determined as a number from 0 to 100 on the scales A or D. The higher the num
34、ber, the higher the hardness of the material. The Shore A is used for (very) flexible types and the Shore D for flexible and more rigid types. The Shore A and D ranges do overlap. Therefore, for designation purposes a parameter combining the hardness ranges of the Shore A and D is used as this scale
35、 which covers the whole range and is able to discriminate between rather flexible, medium and rigid materials. For values around and above 50 this parameter is identical to the Shore D hardness.3.5.3 Tensile modulus of elasticityThe tensile modulus of elasticity shall be determined in accordance wit
36、h ISO 527 (all parts).The possible values of the tensile modulus of elasticity are divided into 10 ranges, each represented by a 3-figure code-number as specified in Table 4.6 ISO 2014 All rights reservedBS ISO 16365-1:2014ISO 16365-1:2014(E)Table 4 Code-numbers used for tensile modulus of elasticit
