    Withdrawn Rationale:

    This test method covers the determination of the copper number of bleached and purified paper and paperboard, except those containing calcium sulfite, zinc sulfide, melamine resin, urea-formaldehyde resin, starch, rosin size, or other copper-reducing nonfibrous materials. Paper containing such additives can be tested only if the amount and reducing power of the added material is known.

    Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, this test method was withdrawn in September 2009 due to insufficient committee interest in reviewing and revising the standard.

    1. Scope

    1.1 This test method (1, 2, 3, and 4) covers the determination of the copper number of bleached and purified paper and paperboard, except those containing calcium sulfite, zinc sulfide, melamine resin, urea-formaldehyde resin, starch, rosin size, or other copper-reducing nonfibrous materials. Paper containing such additives can be tested only if the amount and reducing power of the added material is known.

    1.2 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.
