Over deze norm
1.1 This test method covers an instrumental method for the CIE (Commission International de l’Eclairage) tristimulus measurement of the color of maleic anhydride melt before and after prolonged heating under specified conditions of time and temperature. The measurement is converted to color values in the platinum-cobalt system.
1.2 This test method covers the range 0 to100 Pt-Co color.
1.3 In determining the conformance of the test results using this method to applicable specification, results shall be rounded in accordance with the rounding off methods of Practice .
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 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. For specific hazard statements, see Sections , , and .
1.6 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.
