22、 BSI ii Foreword ISO (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 interested in a subject for w
23、hich 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 Electrotechnical Commission (IEC) on all
24、 matters of electrotechnical standardization. Draft International Standards adopted by the technical 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. International Standard ISO
25、14663-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. ISO 14663 consists of the following parts, under the general title Plastics Ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion materials: Part 1: Designation system and basis for
26、specifications Part 2: Preparation of test specimens and determination of properties EN ISO 14663-1:2006 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 02:48:52 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 Plastics Ethylene/vinyl alcohol (EVOH) copolymer moulding and extrusion materials Part
27、 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 alcohol (EVOH) copolymer
28、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, colorants, fillers
29、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 colorants, additive
30、s, 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 material for a particular
31、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 application or to ensur
32、e 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 time of publication
33、, 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.

36、e designation system for thermoplastics is based on the following standardized pattern: Designation Identity block Description block 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 op
37、tional 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: Identifi
38、cation of the plastic by its symbol EVOH in accordance with ISO 1043-1 and information about the polymerization process or composition 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 sup
39、plementary information (see 3.2). Data block 3: Designatory properties (see 3.3). Data block 4: Fillers or reinforcing materials and 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 infor
40、mation is not relevant to this part of ISO 14663. The first character of the individual-item block shall be a hyphen. The five data 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 D
41、ata block 1 In this data block, after the hyphen, ethylene/vinyl alcohol copolymers are identified by the symbol EVOH, in accordance 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.

47、 (c) BSI 4 3.3 Data block 3 In this data block, the melt mass-flow rate is represented by a single code-letter (indicating the conditions of measurement) immediately followed by a three-figure code-number (indicating the range in which the value falls). If a value falls on or near a range limit, the
48、 manufacturer shall state which 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. The melt mass-flow rate shall be determined in accordance with ISO 1133, using set of
49、conditions X1) (see table 3). Set of conditions D is intended for comparisons with PE, E/VAC or other polymers, provided the melting point of the ethylene/vinyl alcohol copolymer is below 190 C.
