【国外标准】 Standard Test Method for Sulfur Dioxide in White Pigment Separated from Solvent-Reducible Paints (Withdrawn 2023)

4.1 Calcium sulfate pigments such as titanium-calcium have been used in paints in varying degrees in the past years. As such it is useful to the formulator and the user to be able to monitor the amount of this compound in whole paints.1.1 This test method covers the determination of sulfur dioxide in white pigment separated from solvent-reducible paints.1.2 This test method is not applicable in the presence of sulfides decomposable under the conditions given.1.3 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 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 and health practices and determine the applicability of regulatory limitations prior to use.
