适用范围：1 This part of ISO 4613 establishes a system of designation for ethylene/vinyl acetate thermoplastic material, which may be used as the basis for specifications. 2 The types of E/VAC plastics are differentiated from each other by a classification system based on appro-priate levels of the designator/ properties 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. 3 This part of ISO 4613 is applicable to all ethylene vinyl acetate copolymers containing from 3 % (m/m) to 50 % (m/m) (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. 4 It is not intended to imply that materials having the same designation give necessarily the same perform-ance. This part of ISO 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 required, they shall be determined in accordance with the test methods specified in ISO 4613-2, if suitable. 5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see clause 3, introductory paragraph).
