ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to deve

17、sions and latices and identifies the test methods applicable for determining 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 che

18、mical composition or to those to be used for specific applications.NOTE When 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 are intended to be the subject of an agreement between the intereste

19、d parties.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
