The work of preparing International Standards is normally carried out through ISO technical committe
18、es. Each member bodyinterested in a subject for which a technical committee has beenestablished 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 closel ywith the Intern
19、ational 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 task of technical committees is to prepare International Standards. Draft International Stan
20、dardsadopted 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. Attention is drawn to the possibility that some of the elements of this document may be the subjec
21、t 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, Thermoplasticmaterials. ISO28941 consists of the following parts, under the general title Plastics Poly(phenyle
22、neether) (PPE)moulding and extrusion materials: Part 1: Designation system and basis for specifications ISO 28941-1 is a revision of ISO 15103-1, the revisionconcerning principally the inclusion of melt volume-flowrate as a designatory property and the inclusion of additional ranges of values of the
23、 other designatoryproperties. In order to giveusers time to switch from ISO 15103-1 to ISO 28941-1, ISO15103-1 will remain in force for a number of years after publication of ISO 28941-1. During this period, ISO 15103-2 will effectively be Part 2 of this International Standard. BS EN ISO 28941-1:200

25、s,which may be used as the basis for specifications. 1.2 The types of PPE plastic are differentiated from each other bya classification system based on appropriate levels of the designatorypropertiesa) temperature of deflection under load b) melt volume-flow rate c) Charpy notched impact strength d)
26、 flammabilityand oninformation about basic polymer parameters, intended application and/or method 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 orpol
27、yamide or other materials.It applies to materials ready for normal use in the form of powder, granules or pellets and to materialsunmodified or modified by colorants, additives, fillers, etc.1.4 It is not intended to imply that materials having the same designation necessarily have the sameperforman
28、ce. This part of ISO 28941 does not provide engineering data, performance data or data onprocessing conditions which may be required to specifya material for a particularapplication and/or method of processing. If such additional properties are required, they shall be determined in accordance with t
