18、e 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 which a technical committ
19、ee 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 matters of electrotechn
20、ical 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 the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted i
21、n 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
22、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.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute a

24、lowing URL: www.iso.org/iso/foreword.html.This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.This first edition of ISO 20557-1 cancels and replaces ISO 28941-1:2008, which has been technically revised to introduce a new designation syste
25、m.The revised designation system is published under a new ISO number, as many existing documents refer to ISO 289411. If the existing ISO 289411would be replaced by the new designation system, these documents would refer to the incorrect designation system.The new designation system according to ISO
26、 205571 is intended to replace gradually any designation system according to ISO 289411.A list of all parts in the ISO 20557 series can be found on the ISO website.iv ISO 2018 All rights reservedBS EN ISO 205571:2018Plastics - Poly(phenylene ether) (PPE) moulding and extrusion materials Part 1: Desi
27、gnation system and basis for specifications1 ScopeThis document establishes a system of designation for poly(phenylene ether) (PPE) thermoplastic materials, which can be used as the basis for specifications.The types of poly(phenylene ether) (PPE) materials are differentiated from each other by a cl
28、assification system based on appropriate levels of the designatory properties:a) temperature of deflection under load;b) melt volume-flow rate;c) Charpy notched impact strength;d) flammability;and on information about basic polymer parameters, intended application and/or method of processing, import
29、ant properties, additives, colorants, fillers and reinforcing materials.This document is applicable to all PPE materials, including those modified with polystyrene or polyamide or other materials.It applies to materials ready for normal use in the form of powder, granules or pellets and to materials
30、 unmodified or modified by colorants, additives, fillers, etc.It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to spec
31、ify a material for a particular application and/or method of processing. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20557-2, if suitable.In order to specify a thermoplastic material for a particular application
32、or to ensure reproducible processing, 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 some or all of their content constitutes requirements of this document.

37、 Standard number and an individual-item block. For unambiguous coding, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: Identification of the plastic by its symbol PPE in accordance with ISO 1043-1 and information about the composition
38、 of the polymer (see 4.2). Data block 2: Fillers or reinforcing materials and their nominal content (see 4.3). Data block 3: Position 1: intended application or method of processing (see 4.4).Positions 2 to 8: important properties, additives and supplementary information (see 4.4). Data block 4: Des
39、ignatory properties (see 4.5). Data block 5: For the purposes of specifications, a fifth data block may be added containing additional information (see 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 bloc
40、k is not used, this shall be indicated by doubling the separation sign, i.e. by two commas (,).4.2 Data block 1In this data block, after the hyphen, poly(phenylene ether) materials are identified by the symbol PPE, in accordance with ISO 10431, followed by a hyphen and a codenumber giving additional
