21、-li1999 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for w
22、hich a technical committee has been established 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. IS0 colla borates closely with the International Electrotechnical Commission (IEC) on al
23、l matters of electrotechnical standardization. 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. International Standard IS0

28、erties a) vinyl acetate content b) melt flow rate and on information about intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 This part of IS0 4613 is applicable to all ethylene vinyl acetate copolymers containing from
29、 3 % (dm) to 50 % (dm) (approximately 25 % molar) of vinyl acetate. It applies to materials ready for normal use in the form of powder, 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 de
30、signation give necessarily the same perform- ance. This part of IS0 4613 does not provide engineering data, performance data or data on processing conditions which may be required to specify a material for a particular application and/or method of processing, If such additional properties are requir
31、ed, they shall be determined in accordance with the test methods specified in IS0 4613-2, if suitable. 1.5 additional requirements may be given in data block 5 (see clause 3, introductotv paragraph).
