C957 currently references ASTM C1250 as the test method for determining weight loss after heating; however, C1250 is scheduled to be withdrawn. This Work Item is intended to change the test method from C1250 to D6511. This change in test methods does not change the temperature or duration of heating prior to measuring weight loss.
