Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO membe
13、r 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, governmenta
14、l 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 Directi
15、ves, 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 possibility that some of the eleme
16、nts of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 12000 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 9, Thermoplastic materials, in collaborati
17、on with ISO/TC 45,Rubber and rubber products. This second edition cancels and replaces the first edition (ISO 12000:1996), in which the reference to the test methods have been updated.

18、IONAL STANDARD?ISO 12000:2000(E) ?1 Plastics/rubber Polymer dispersions and rubber latices (natural and synthetic) Definitions and review of test methods 1?Scope This International Standard gives definitions relative to polymer dispersions and latices and identifies the test methods applicable for d
19、etermining the properties of polymer dispersions, comprising products of synthetic or natural origin including synthetic and natural rubber latices. Some of the test methods apply only to polymer dispersions or latices of specific chemical composition or to those to be used for specific applications
20、. NOTE?Where they are not the subject of an existing International Standard, the test methods to be used for investigation of an individual polymer dispersion or latex will have to be the subject of agreement between the interested parties. 2?Normative references The following normative documents co
21、ntain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, these publications do not apply. However, parties to agreements based on this International Standard are encouraged to invest
22、igate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

37、the purposes of this International Standard, the following terms and definitions apply. 3.1 dispersion a heterogeneous system in which a finely divided material is distributed in another material ISO 472:1999 3.2 polymer dispersion (dispersion of natural or synthetic homopolymer and copolymer) a liq
38、uid to semi-liquid material, usually milky-white, containing the polymeric material in a stable condition finely dispersed in a continuous liquid phase, normally water 3.3 latex the traditional designation for a colloidal aqueous dispersion of natural or synthetic rubber polymer NOTE 1?Frequently, “
39、latex” is also used as a synonym for polymer dispersions in general. NOTE 2?Polymer dispersions and latices are often further explained by adding the designation of the base polymer by name or by abbreviation, for instance polyacrylate dispersion, SBR latex. 4?Sampling Sampling shall be carried out
40、in accordance with ISO 123 (rubber latex). Representative samples of polymer dispersions and of latices are a prerequisite for reliable and reproducible results from the test methods. Therefore the material to be tested must be uniform. 5?Conditioning The conditioning and testing atmosphere shall co
41、mply with the specified test method or referring standard, as applicable. If there are no such requirements, then samples shall be conditioned and tests carried out in one of the standard atmospheres specified in either ISO 291 for polymer dispersions or ISO 471 for latices, as appropriate.
