significance And Use:

This guide includes chromates that are not readily soluble in water and that have water solubilities (Chromate ION) within the range of the more soluble calcium chromate and the much less soluble... View More

scope:

1.1 This guide covers control procedures for the safe production, storage, transportation, and handling of only the hexavalent chromium compounds found in and their various hydrates, and mixtures of coprecipitates of the same regardless of crystalline form.

1.2 This guide is not intended to cover ( a) such "soluble" chromates as chromates of sodium, potassium, magnesium, or ammonium; (b) soluble bichromates; (c) chromic acid; (d) volatile chromyl compounds; (e) any trivalent chromium compound; or (f) elemental chromium. Omission of said compounds or classes of compounds should not be construed to mean that they may be handled without due regard to their particular physical, chemical, and toxicological hazards (, , ).

1.3 The chromate ion, CrO42, depending upon the acidity, complexes to form di-, tri-, and higher polychromates; hence, the chromates listed in may contain mixtures of polychromates, depending on the method of isolation and end use.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (For more specific precautionary information see Section 5.)
