9、on system and basis for specifications 1 Scope 1.1 This part of ISO 14910 establishes a system of designation for thermoplastic polyester/ester and polyether/ester elastomers, which may be used as the basis for specifications. 1.2 The types of thermoplastic polyester/ester and polyether/ester elasto

10、mer 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 elasticity; and on information about the intended application and/or method of processing, important properties

11、, additives, colourants, fillers and reinforcing materials. 1.3 This part of ISO 14910 is applicable to all thermoplastic 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, fil

12、lers or other additives. 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 14910 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a par

13、ticular 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 polyester/ester or polyether/ester materi

14、al for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see clause 3, introductory paragraph). 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this pa

All standards are subject to revision, and parties to agreements based on this part of ISO 14910 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

Only information listed in data block 5 becomes part of the specification requirements. The first character of the individual-item block shall be a hyphen. The data blocks shall be separ

22、ated from each other by commas. If a data block is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,). 3.1 Data block 1 In this data block, after the hyphen, thermoplastic polyester/ester and polyether/ester elastomers are identified using the symbols and desig

One segment of a pol

45、yester/ester copolymer is built up from a starting material with hydroxyl (-OH) groups, also called diols, plus a starting material with carboxylic acid (-COOH) groups, also called dicarboxylic acids, or esters of such acids, and the second segment is built up from a hydroxycarboxylic acid or its la

46、ctone, in each case by a polycondensation process. One segment of a polyether/ester copolymer is built up from diols and dicarboxylic acids, or esters of such acids, and the second segment is built up from polyalkylene ether glycols and dicarboxylic acids, in each case by a polycondensation process.

47、 Aliphatic polyester segments based on linear diols and linear dicarboxylic acids or esters of such acids are designated by two or more code-numbers. The first code-number (which may have one or two digits) corresponds to the number of C-atoms in the linear diol (see table A.1) and the second code-n

48、umber (which may also have one or two digits) corresponds to the number of C-atoms in the linear dicarboxylic acid (see table A.2). Non-linear aliphatic, cycloaliphatic and aromatic compounds used as monomer units in the polyester chain are designated by code-letters (see tables A.1, A.2 and A.3). Copolyesters are designated by an oblique stroke (/) between the code-numbers representing the components of the copolyester (cf annex A, clause A.6, in ISO 104
