9、Uncontrolled Copy, (c) BSI b Introduction This draft standard is based on European discussions in which the UK took an active part. Your comments on this draft are welcome and will assist in the preparation of the consequent British Standard. If no comments are received to the contrary, then the UK
10、will approve this draft and implement it as a British Standard. Comment is particularly welcome on national, legislative or similar deviations that may be necessary. Even if this draft standard is not approved by the UK, if it receives the necessary support in Europe, the UK will be obliged to publi
11、sh the official English Language text unchanged as a British Standard and to withdraw any conflicting standard. UK Vote Please indicate whether you consider the UK should submit a negative (with reasons) or positive vote on this draft. Submission The guidance given below is intended to ensure that a
12、ll comments receive efficient and appropriate attention by the responsible BSI committee. Annotated drafts are not acceptable and will be rejected.

34、 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 committee has been established has the right to be represented on that committee. International organizations, gover
35、nmental 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 electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC D
36、irectives, Part 2. The main task 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
37、bodies casting a vote. 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. ISO 28941-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommit
38、tee SC 9, Thermoplastics. 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 15103 Part 2:Preparation of test specifiments and determination of properties

40、 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 from each other by a classification system ba
41、sed on appropriate levels of the designatory properties a) temperature of deflection under load b) Charpy notched impact strength c) flammability and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers a
42、nd 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 powder, granules or pellets and to materials unmodified or modified by colora
43、nts, additives, fillers, etc. 1.4 It is not intended to imply that materials having the same designation give necessarily the same performance. This part of ISO 28941 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for
44、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 part 2 of this International Standard, if suitable. 1.5 In order to specify a thermoplastic material for a particular applicatio
45、n or to ensure reproducible processing, additional requirements may be given in data block 5 (see 3.1). 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 28941. For dated references, subsequent
46、 amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 28941 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
