The work of pr
19、eparing International Standards is normally 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 non-governmental, i
20、n liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main tas
21、k of technical committees is to prepare International Standards. 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. Attentio
22、n 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. ISO 28941-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materia
23、ls. ISO 28941 consists of the following parts, under the general title Plastics Poly(phenylene ether) (PPE) moulding and extrusion materials: Part 1: Designation system and basis for specifications ISO 28941-1 is a revision of ISO 15103-1, the revision concerning principally the inclusion of melt vo
24、lume-flow rate as a designatory property and the inclusion of additional ranges of values of the other designatory properties. In order to give users time to switch from ISO 15103-1 to ISO 28941-1, ISO 15103-1 will remain in force for a number of years after publication of ISO 28941-1. During this p
25、eriod, ISO 15103-2 will effectively be Part 2 of this International Standard.

26、r) (PPE) moulding and extrusion materials Part 1: Designation system and basis for specifications 1 Scope 1.1 This part of ISO 28941 establishes a system of designation for PPE thermoplastic materials, which may be used as the basis for specifications. 1.2 The types of PPE plastic are differentiated
27、 from each other by a classification 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 meth
28、od of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of ISO 28941 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 powde
29、r, granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation necessarily have the same performance. This part of ISO 28941 does not provide engineering data, performance data or data o
30、n processing conditions which may be required to specify a material for a particular application and/or method of processing. If such additional properties are required, they shall be determined in accordance with the test methods specified in ISO 15103-2, if suitable. 1.5 In order to specify a ther
31、moplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1).

For unambiguous coding, the individual-item block is subdivided into five data blocks comprising the following information: Data block 1: Identification of the pla

Data block 2: Position 1: intended application or method of processing (see 3.3). Positions 2 to 8: important properties, additives and supplementary information (see 3.3). Data block
37、 3: Designatory properties (see 3.4). Data block 4: Fillers or reinforcing materials and their nominal content (see 3.5). Data block 5: For the purposes of specifications, a fifth data block may be added containing additionalinformation. The first character of the individual-item block shall be a hy

46、me-flow rate by a two-figure code-number (see 3.4.3), the impact strength by a two-figure code-number (see 3.4.4) and the flammability by a combination of code-letters and code-numbers indicating the flammability category (see 3.4.5). The code-numbers are separated from each other by hyphens. If a p

If subsequent individual test values lie on, or on either side of, the limit because of manufacturing tolerances, the designation is not affected. NOTE Not all combinations of the valu
