Basic Information
Scope
Main technical content: This document specifies the high-performance liquid chromatography method for determining the content of Solvent Blue 4, Basic Violet 3, Basic Blue 26, Direct Red 28, Direct Black 38, α,α-bis((dimethylamino)phenyl)-4-aminobenzoic acid, 1,2-anhydride of benzene-1,2,4-tricarboxylic acid (phthalic anhydride), 4,4'-bis((dimethylamino)phenyl) benzophenone (Miescher's ketone), and N,N,N',N'-tetramethyl-4,4'-diaminodiphenylmethane (Miescher's base) (hereinafter collectively referred to as dye compounds) in automotive and automotive parts materials. This document is applicable to the determination of dye compounds in plastics, rubber, and coatings in automotive products. Other products with materials that have been verified to be suitable may also be measured using this method.
