Developed by Subcommittee: D06.92
WITHDRAWN, NO REPLACEMENT
This test method covers the determination of the alkalinity or alkaline reserve of paper, or both.
Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, this test method was withdrawn in May 2010 because equivalent TAPPI and ISO publications exist.
1.1 This test method covers the determination of the alkalinity or alkaline reserve of paper, or both.
1.2 A qualitative test is described that indicates the presence of carbonate. (The detection limit is approximately 5 % calcium carbonate.)
1.3 A qualitative test is described that determines the alkalinity expressed as percent calcium carbonate or alkaline reserve, or both, expressed as moles per kilogram of paper. Note 1 - A similar procedure for measuring the alkalinity or alkaline reserve or both of paper will be found in ISO 10716.
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.
