Pigment manufacturers use the loss on ignition test to determine water of hydration or crystallized water. While loss on ignition is a frequently used test, its methodology is embedded within other standards and varies from one to another. Now, a proposed new standard, ASTM WK46877, Test Method for Pigment Loss on Ignition, will provide definitive instructions for conducting this common test. “…, ASTM Committee D01 Next Meeting:, Jan. 25-27, 2015, January Committee Week, New Orleans, La., Technical Contact:, Steven Brunner, WPC Technologies, Milwaukee, Wis., Phone: 414-225-2415; sbrunner@wpctech.com, ASTM Staff Contact:, Jeffrey Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #9682
