The work of preparing International Standards is n

18、ormally 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 nongovernmental, in liaison with ISO, also take part in

19、 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular t

20、he 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 the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this docu

21、ment 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 during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.or

25、sis for specifications1 ScopeThis document establishes a system of designation for poly(vinyl alcohol) (PVAL) materials which may be used as the basis for specifications.The types of poly(vinyl alcohol) (PVAL) materials are differentiated from each other by a classification system based on the desig

26、natory properties:a) degree of hydrolysis,b) viscosity of aqueous solution under defined conditionsand on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.This document is appli

27、cable to all poly(vinyl alcohol) (PVAL) materials with a degree of hydrolysis not less than 70 mol%.It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc.It is not intended to imply that m

28、aterials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which may be required to specify a material. If such additional properties are required, they are intended to be determined i

29、n accordance with the test methods specified in ISO 15023-2, if suitable.In order to designate a thermoplastic material to meet particular specifications, the requirements are given in data block 5 (see 4.1).2 Normative referencesThe following documents are referred to in the text in such a way that

For unambiguous designation, the individual-item bl

35、ock is subdivided into five data blocks comprising the following information:Data block 1: Identification of the plastic by its abbreviated term, PVAL, in accordance with ISO 10431 (see 4.2).Data block 2: Fillers or reinforcing materials and their nominal content (see 4.3).Data block 3: Position 1:

36、Intended application and/or method of processing (see 4.4).Positions 2 to 8: Information about important properties, additives and colour (see 4.4).Data block 4: Designatory properties (see 4.5).Data block 5: For the purpose of specifications, the fifth data block contains appropriate information (s

37、ee 4.6).The first character of the individual-item block shall be a hyphen. The 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 (,).Terminal commas may be omitted. For part marking, the
