Причина отмены

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

Formerly under the jurisdiction of Committee D06 on Paper and Paper Products, these test methods were withdrawn in May 2010 because equivalent TAPPI and ISO publications exist.

Значение и использование

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.
