(Specification)Standard Specification for Chrome Yellow and Chrome Orange Pigments
Standard Specification for Chrome Yellow and Chrome Orange Pigments
ABSTRACT
This specification covers commercially pure chrome yellow and chrome orange pigments. The chemically precipitated pigments should consist of normal or basic lead chromates, or mixtures of these, with or without admixtures of other insoluble lead compounds. Pigment composition should conform to the required amounts of lead chromate, total matter soluble in water, total of all substances other than insoluble lead compounds, moisture and volatile matter, coarse particles, and organic colors and lakes for each of the six types.
SCOPE
1.1 This specification covers six types of commercially pure lead chromate pigments as follows:
Type I—Primrose Chrome Yellow,
Type II—Lemon Chrome Yellow,
Type III—Medium Chrome Yellow,
Type IV—Light Chrome Orange,
Type V—Dark Chrome Orange, and
Type VI—Chrome Yellow for Green.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 The following hazard caveat applies to the test method portion of this specification only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
