【国外标准】 Standard Practice for Determining Volatile and Nonvolatile Content of Cellulosics, Emulsions, Resin Solutions, Shellac, and Varnishes

4.1 The nonvolatile content of raw materials may be used to determine the total nonvolatile content (solids) of paint and related coatings. Such information may be useful to coatings producers and users for the determination of the total solids available for film formation and for the estimation of the volatile organic content.1.1 This practice is intended to serve as a guide to the selection of the proper ASTM test method for determining the volatile and nonvolatile content of cellulosics, emulsions, resin solutions, shellac, and varnishes.NOTE 1: Standards for determining the composition of the volatile fraction are not covered by this practice.1.2 The standards referenced in the practice are as follows:Classification Section ASTM StandardCellulosics 5.1 D871    D914    D1347Emulsions 5.2 D2369Resin Solutions 5.3 D1259    D1490Shellac 5.4 D29    D1650Varnishes 5.5 D115    D16441.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 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.
