【国外标准】 Standard Test Methods for Chemical Analysis of Blue Pigments

3.1 These test methods are suitable for determining if impurities are present and establishing that the required pigments are present. These test methods may be used for manufacturing quality control.1.1 These test methods cover procedures for the chemical analysis of blue pigments known commercially as iron blue, copper phthalocyanine blue, and ultramarine blue.1.2 The analytical procedures appear in the following order:  Sections IRON BLUE PIGMENTS Identification  6Moisture by the Brabender Moisture Tester  7 and 8Moisture by Toluene Distillation  9Water-Soluble Matter by Extraction 10Water-Soluble Salts by Electrical Conductivity 11Detection of Acid-Insoluble Extenders 12 and 13Detection of Acid-Soluble Extenders 14 to 17Detection of Organic Colors and Lakes 18 COPPER PHTHALOCYANINE BLUE PIGMENTS Identification 19Moisture and Other Volatile Matter 20Detection of Basic Dye Derivatives 21Detection of Other Organic Coloring Matter 22Detection of Ultramarine Blue 23Detection of Iron Blue 24 ULTRAMARINE BLUE Identification 25Moisture and Other Volatile Matter 26Water-Soluble Matter 27Detection of Basic Dye Derivatives 28Detection of Other Organic Coloring Matter 291.3 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.
