16、This part of ISO 14663 establishes a system of designation for ethylene/vinyl alcohol (EVOH) copolymerthermoplastic materials, which may be used as the basis for specifications.1.2 The types of ethylene/vinyl alcohol (EVOH) copolymer plastic are differentiated from each other by aclassification syst
17、em based on appropriate levels of the designatory property:melt mass-flow rateand on information about basic polymer parameters, intended application and/or method of processing, importantproperties, additives, colorants, fillers and reinforcing materials.1.3 This part of ISO 14663 is applicable to
18、copolymers of ethylene and vinyl alcohol containing from 15 % (m/m) to60 % (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, additives, fillers, etc.1.4 It is not intended to imply that materials having the
19、 same designation give necessarily the same performance.This part of ISO 14663 does not provide engineering data, performance data or data on processing conditionswhich may be required to specify a material for a particular application and/or method of processing.If such additional properties are re
20、quired, they shall be determined in accordance with the test methods described inpart 2 of this International Standard, if suitable.1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing,additional requirements may be given in data block 5
21、(see clause 3, introductory paragraph).2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of this part ofISO 14663. At the time of publication, the editions indicated were valid. All standards are subject to revision, andpart
22、ies to agreements based on this part of ISO 14663 are encouraged to investigate the possibility of applying themost recent editions of the standards indicated below.

25、block1Datablock2Datablock3Datablock4Datablock5The designation consists of an optional description block, reading “Thermoplastics”, and an identity blockcomprising the International Standard number and an individual-item block. For unambiguous designation, theindividual-item block is subdivided into
26、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 informationabout the polymerization process or composition of the polymer (see 3.1). Data block 2: Position 1: Intended application or method of pro
27、cessing (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 and their nominal content (see 3.4). Data block 5: For the purpose of specifications, a fifth da
28、ta 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 blocks shall be separated from eachother by commas. If a data block is not used, this shall be
29、indicated by doubling the separation sign, i.e. by twocommas (,).3.1 Data block 1In this data block, after the hyphen, ethylene/vinyl alcohol copolymers are identified by the symbol EVOH, inaccordance with ISO 1043-1, and, after a space, a two-figure code-number giving the ethylene content of thecop

36、hich range will designate the material. Ifsubsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, thedesignation is not affected.The melt mass-flow rate shall be determined in accordance with ISO 1133, using set of conditions X1)(see table 3).Se
