International Organization for Standardization Case postale 56 CH-1211 Genve 20 Switzerland Internetisoiso.ch Printed in Switzerland ii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The
5、 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 non-gove
6、rnmental, 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for v
7、oting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 14663-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. ISO 14663 consists of the following parts, u

10、sion materials Part 1: Designation system and basis for specifications 1 Scope 1.1 This part of ISO 14663 establishes a system of designation for ethylene/vinyl alcohol (EVOH) copolymer thermoplastic materials, which may be used as the basis for specifications. 1.2 The types of ethylene/vinyl alcoho
11、l (EVOH) copolymer plastic are differentiated from each other by a classification system based on appropriate levels of the designatory property: melt mass-flow rate and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives,
12、colorants, fillers and reinforcing materials. 1.3 This part of ISO 14663 is applicable to copolymers of ethylene and vinyl alcohol containing from 15 % (m/m) to 60 % (m/m) of ethylene. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by
13、colorants, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 14663 does not provide engineering data, performance data or data on processing conditions which may be required to specify a materia
14、l for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods described in part 2 of this International Standard, if suitable. 1.5 In order to specify a thermoplastic material for a particular appl
15、ication 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 part of ISO 14663. At the
16、time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 14663 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

20、k International Individual-item block (optional) Standard number block Data block 1 Data block 2 Data block 3 Data block 4 Data block 5 The designation consists of an optional description block, reading “Thermoplastics”, and an identity block comprising the International Standard number and an indiv
21、idual-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 plastic by its symbol EVOH in accordance with ISO 1043-1 and information about the polymerization process or composit
22、ion of the polymer (see 3.1). Data block 2: Position 1: Intended application or method of processing (see 3.2). Positions 2 to 8: Important properties, additives and supplementary information (see 3.2). Data block 3: Designatory properties (see 3.3). Data block 4: Fillers or reinforcing materials an
23、d their nominal content (see 3.4). Data block 5: For the purpose of specifications, a fifth data block may be added containing additional information. This kind of information is not relevant to this part of ISO 14663. The first character of the individual-item block shall be a hyphen. The five data
24、 blocks shall be separated 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, ethylene/vinyl alcohol copolymers are identified by the symbol EVOH, in accordanc
25、e with ISO 1043-1, and, after a space, a two-figure code-number giving the ethylene content of the copolymer as specified in table 1.
