19、onal 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. Internat
20、ional 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 ru
21、les given in the ISO/IEC Directives, Part 3. 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 po
22、ssibility that some of the elements of this part of ISO 6744 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

It is also applicable to those solutions and similar preparations made from alkyd resins that a
26、re intended for use as binders for paints and varnishes. The test methods to be used for an individual alkyd resin shall be the subject of agreement between the interested parties. 2 Normative references The following normative documents contain provisions which, through reference in this text, cons

36、phenolic resins, vinyl toluene, styrene, isocyanates, polyamides or acrylic, epoxy or silicone compounds NOTE An alkyd resin based on tall-oil fatty acids containing not more than 4 % of rosin acids is regarded as an “alkyd resin“, not as a “modified alkyd resin“. 4 Classification Alkyd resins are c
37、lassified into the following groups: a) according to the content of fatty acid or oil (content of oil calculated as the triglyceride portion of the non- volatile matter): short-oil alkyd resins: less than about 40 % medium-oil alkyd resins: about 40 % to 60 % long-oil alkyd resins: above about 60 %
38、b) according to the content of dibasic acid (see ISO 6744-2); c) according to the modifying component (see 3.2). 1) To be published.
