    Significance and Use

    These test methods are suitable for determining if impurities are present and establishing that the required pigments are present. These test methods may be used for manufacturing quality control.

    1. Scope

    1.1 These test methods cover procedures for the chemical analysis of blue pigments known commercially as iron blue, copper phthalocyanine blue, and ultramarine blue.

    1.2 The analytical procedures appear in the following order:

    Sections
    I ron Blue Pigments
    Identification 6
    Moisture by the Brabender Moisture Tester 7 and 8
    Moisture by Toluene Distillation 9
    Water-Soluble Matter by Extraction10
    Water-Soluble Salts by Electrical Conductivity11
    Detection of Acid-Insoluble Extenders1213
    Detection of Acid-Soluble Extenders14 to 17
    Detection of Organic Colors and Lakes18
    C opper Phthalocyanine Blue Pigments
    Identification19
    Moisture and Other Volatile Matter20
    Detection of Basic Dye Derivatives21
    Detection of Other Organic Coloring Matter22
    Detection of Ultramarine Blue23
    Detection of Iron Blue24
    U ltramarine Blue
    Identification25
    Moisture and Other Volatile Matter26
    Water-Soluble Matter27
    Detection of Basic Dye Derivatives28
    Detection of Other Organic Coloring Matter29

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 This standard does not purport to address the safety concerns 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.

    12.1 Acid-insoluble extenders include barium sulfate, silica, and silicates. Alumina may also be found, in part, with this group.

    14.1 Acid-soluble extenders include the alkaline earth carbonates or sulfates, magnesium carbonate, and alumina hydrate.
