【国外标准】 Standard Test Methods for Analysis of Yellow, Orange, and Green Pigments Containing Lead Chromate and Chromium Oxide Green

4.1 These test methods are for analysis designed as an aid in quality of yellow, orange, and green pigments containing lead chromate and chromium oxide green. Some sections may be applicable to analysis of these pigments when extracted from whole paints.1.1 These test methods cover procedures for the chemical analysis of yellow, orange, and green pigments containing lead chromate and chromium oxide green.1.2 The analytical procedures appear in the following order:  SectionsChrome Yellow, Chrome Orange, and Molybdate OrangeOrganic Colors and Lakes 7Moisture and Other Volatile Matter 8Matter Soluble in Water 9Lead Chromate 10 and 11Total Lead 12Sulfate 13 and 14Carbon Dioxide 15Molybdenum 16 and 17Extenders 18 – 22Calculation of Substances Other than Insoluble Lead Compounds  23 and 24Pure Chrome Green and Reduced Chrome GreenOrganic Colors and Lakes 25Moisture and Other Volatile Matter 26Matter Soluble in Water 27Iron Blue 28Lead Chromate 29 and 30Barium Sulfate and Insoluble Siliceous Material 31Total Lead 32Sulfate 33Calcium Oxide Soluble in Acid 34 and 35Extenders 36Calculation of Insoluble Lead Compounds  37Chromium Oxide GreenOrganic Colors and Lakes 38Moisture and Other Volatile Matter 39Matter Soluble in Water 40Total Chromium as Chromium Oxide 411.3 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 problems, 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. Specific hazard statements are given in Note 3.1.5 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.
