【国外标准】 Standard Practice for Separation of Vehicle From Solvent-Reducible Paints

3.1 Separation of the vehicle from the pigment in solvent-reducible paints is required in order to characterize paint vehicles by chemical, spectroscopic, or chromatographic techniques. Characterization of vehicles is important since they play a major role in the performance of coatings.1.1 This practice covers the procedure for the separation of the vehicle from the pigment in solvent-reducible paint.1.2 In the development of the practice the following materials were tested: white soya and white fish oil isophthalic alkyd semi-gloss enamels, white linseed oil paint, white soya and white linseed o-phthalic alkyd enamels. It is considered to be applicable to similar materials.1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
