It is identical with Internation
4、al Standard ISO 7143 which was prepared by ISO/TC 35/SC 10 “Test methods for binders for paints and varnishes” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Beschichtungsstoffe und Beschichtungen (Coatings and Coating Materials Standards
5、 Committee), Technical Committee NA 002-00-02 AA Lackrohstoffe. 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 properties. ISO 12000 covers both aqueous and non-aqueous polyme
6、r dispersions, and products of synthetic and natural origin, including synthetic rubber lattices. It was prepared by Technical Committee ISO/TC 61 “Plastics” Subcommittee SC 9 “Thermoplastic materials”, in close collaboration with ISO/TC 45 “Rubber and rubber products”. The DIN Standards correspondi
7、ng to the International Standards referred to in the EN are as follows: ISO 976 DIN ISO 976 ISO 2115 DIN ISO 2115 ISO 2811-1 DIN EN ISO 2811-1 ISO 3219 DIN EN ISO 3219 ISO 3251 DIN EN ISO 3251 ISO 4576 DIN EN ISO 4576 ISO 4618 DIN EN ISO 4618 ISO 13741-1 DIN ISO 13741-1 ISO 13741-2 DIN ISO 13741-2 I

26、ing 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.

35、t 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 as characterizing properties of water-based binders,
36、 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 report shall contain at least the following information:
37、 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 deviations from the procedures specified; e) the da
38、tes of the tests. 4 EN ISO 7143:2007 (E) Table 1 Characterizing properties and test methods Property Method of test Viscosity ISO 3219 Non-volatile matter ISO 3251 pH-value ISO 976 Sieve residue (gross particle and coagulum content) ISO 4576 Minimum film-forming temperature ISO 2115 Glass transition

40、y), strongly depend on the details of the method. The results obtained by different laboratories can therefore be compared only if common reference samples are used. bThe results of GPC (gel permeation chromatography) analysis are relative values and depend on the separation factor, column material,
41、 detector, etc. The data obtained by different laboratories can therefore be compared only if common reference samples are used. 5 EN ISO 7143:2007 (E) Bibliography 1 ISO 4618:2006, Paints and varnishes Terms and definitions 2 ISO 12000, Plastics/rubber Polymer dispersions and rubber latices (natural and synthetic) Definitions and review of test methods 6 EN ISO 7143:2007 (E)
