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

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
