Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
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. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all 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 ISO 8985 was prepared by Technical Committee
ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
This second edition cancels and replaces the first edition (ISO 8985:1989),
which has been technically revised.

INTERNATIONAL STANDARD  ISO ISO 8985:1998(E)
Plastics – Ethylene/vinyl acetate copolymer (EVAC) thermoplastics –
Determination of vinyl acetate content
1 Scope
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Note – The abbreviation previously used for ethylene/vinyl acetate copolymer (E/VAC) has been replaced by the abbreviation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.
2 Normative references

this International Standard. At the time of publication, the editions indicated were valid. All standards are
subject to revision, and parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the standards indicated below. Members
of IEC and ISO maintain registers of currently valid International Standards.
