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

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

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
