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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10283 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 10,
Test methods for binders for paints and varnishes.
This second edition cancels and replaces the first edition (ISO 10283:1997), in which the normative
references clause has been updated.

ISO 10283:2007(E)
Introduction
It is well-known fact that, due to the production methods used, all the commercial isocyanate resins named in
this standard contain a certain amount of volatile monomeric isocyanates. This amount is generally less than
0,5 % relative to the resin as supplied. In view of the regulations relating to the handling of hazardous
substances, it has become a matter of special concern that a generally accepted and applicable method of
determination should be available. This standard is not intended to present a method suitable for the analytical
determination of volatile isocyanates in any form and in any quantity. The standard specifies a method
confined to determining the amounts of volatile isocyanates which occur in practice in isocyanate resins,
namely about 0,1 % to 0,4 %. A further objective of the standard was to develop a method for determining with
adequate accuracy as many as possible of the monomeric isocyanates which occur in isocyanate resins. It
detects the principle isocyanates, namely toluene diisocyanate (TDI), hexamethylene diisocyanate (HDI),
diphenylmethane diisocyanate (MDI) and isophorone diisocyanate (IPDI), and is a method considered by
industry, authorities and institutes alike to be the state of the art.

Binders for paints and varnishes — Determination of
monomeric diisocyanates in isocyanate resins
1 Scope
This International Standard specifies a gas-chromatographic method for determining monomeric
1) 2)
diisocyanates such as toluene diisocyanate , hexamethylene diisocyanate, isophorone diisocyanate ,
3)
diphenylmethane diisocyanate and other diisocyanates in isocyanate resins as defined in Clause 3 and in
solutions prepared from such resins, insofar as these are used in the formulation of paints and similar coating
materials.
