This International Standard specifies two categories of method for the determination of the vinyl acetate (VAC) content of ethylene/vinyl acetate (EVAC) copolymers, for use in the designation of such copolymers in accordance with ISO 4613-1:1997. One category is referred to as \'reference methods\', the other as \'test methods\'.
Note - The abbreviation previously used for ethylene/vinyl acetate copolymer (E/VAC) has been replaced by the abbreviation EVAC (see ISO 1043-1:1997, Plastics - Symbols and abbreviated terms - Part 1: Basic polymers and their special characteristics).
The \'reference methods\' are used to calibrate the method used for the determination of the vinyl acetate content of ethylene/vinyl acetate copolymers.
The \'test methods\' are other methods which can be used for the determination if they are calibrated using one of the reference methods described in clause 3 provided they show a certain permissible repeatability.
