Plastics. Ethylene-vinyl acetate (EVAC) moulding and extrusion materials. Part 1: Designation system and basis for specifications (ISO 21301-1:2019)

1.1 This document establishes a system of designation for ethylene-vinyl acetate thermoplastic material, which can be used as the basis for specifications.
1.2 The types of ethylene-vinyl acetate (EVAC) plastic are differentiated from each other by a classification system based on appropriate levels of the following designatory properties:
a) vinyl acetate content;
b) melt mass-flow rate;
and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.
1.3 This document is applicable to all ethylene vinyl acetate copolymers containing from a mass fraction from 3 % to 50 % (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 designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material for a particular application and/or method of processing.
If such additional properties are required, they are determined in accordance with the test methods specified in ISO 21301-2, if suitable.
1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements can be given in data block 5 (see 4.1).
