16、ational 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. Inter
17、national 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
18、 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
19、 at least 75 % of the member bodies casting a vote. ISO 7142 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 10, Test methods for binders for paints and varnishes, in collaboration with CEN Technical Committee CEN/TC 139, Paints and varnishes. This third edition
20、cancels and replaces the second edition (ISO 7143:2000), which has been technically revised. The major changes are as follows: a) water-based coating materials have been excluded from the scope because these products are not specified in accordance with this standard; b) the determination of molecul
21、ar mass has been added to Table 1; c) the normative references have been updated and the text has been editorially revised. Readers should note that ISO 12000 gives definitions relative to polymer dispersions and lattices, and identifies the test methods applicable to the determination of their prop
22、erties. ISO 12000 covers both aqueous and non-aqueous polymer dispersions, and products of synthetic and natural origin, including synthetic rubber latices. It was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials, in close collaboration with ISO/TC 45,
23、Rubber and rubber products. EN ISO 7143:2007blank1Binders for paints and varnishes Methods of test for characterizing water-based binders 1 Scope This International Standard specifies methods of test for characterizing binders, i.e. aqueous dispersions and solutions of polymers and copolymers, in pa
24、rticular those used as raw materials for water-based coating materials. The properties determined will depend on whether a drying or curing system is tested. 2 Normative references The following referenced documents are indispensable for the application of this document.

33、 Sampling Take a representative sample of the product to be tested, as described in ISO 15528. 5 Methods of test The test methods used for a particular binder shall be the subject of agreement between the interested parties, if not otherwise specified. The properties given in Table 1 are considered
34、as characterizing properties of water-based binders, in particular if they are used as raw materials for paints and varnishes. If reactive groups, e.g. hydroxyl groups, are to be determined, the test shall be carried out as for organic binders, before diluting with water. 6 Test report The test repo
35、rt shall contain at least the following information: a) a reference to this International Standard (ISO 7143:2007); b) all details necessary for complete identification of the product tested (manufacturer, trade name, batch number, etc.); c) the results of the tests and the test methods used; d) any
36、 deviations from the procedures specified; e) the dates of the tests.
