Standard Test Methods for Zinc and Cadmium in Paper (Withdrawn 2010)

2010-05-01 /Withdrawn
No replacement
Significance and Use:

Zinc is usually present as zinc oxide, zinc sulfide, or as lithopone (a combination of zinc sulfide and barium sulfate), which is occasionally used in filled paper, paper coatings, and high pressure laminates and wallpaper. Some forms of zinc oxide have photoelectric properties and are found in certain papers used for photoreproduction. Zinc or cadmium pigments are sometimes added to papers to cause fluorescence, and zinc oxide has been used to enhance the cohesive strength of some types of paper coatings.


1.1 These test methods cover the determination of cadmium and zinc either in paper or in highly opaque pigments.

1.2 The test methods appear as follows:

Method A-Polarographic5
Method B-Gravimetric and Volumetric6
Method C-Atomic Absorption7

1.3 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.
