Standard Test Methods for
Chemical Analysis of Phthalocyanine Blue and Green
Pigments1
This standard is issued under the fixed designation D 3256; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
a superscript epsilon (e) indicates an editorial change since the last revision or reapproval
1. Scope
1.1 These test methods cover procedures for the qualitative
chemical analysis of pigments known commercially as copper
phthalocyanine blue and green.
1.2 The procedures appear in the following order:
Section
Identification 5
Moisture and Other Volatile Matter 6
Detection of Basic Dye Derivatives 7
Detection of Other Organic Coloring Matter 8
Detection of Ultramarine Blue 9
Detection of Iron Blue or Chrome Green 10
1.3 This standard does not purport to address the safety
concerns, if any, 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.
2. Referenced Documents
2.1 ASTM Standards:
D 280 Test Methods for Hygroscopic Moisture (and Other
Matter Volatile Under the Test Conditions) in Pigments2
D 1193 Specification for Reagent Water3
3. Significance and Use
3.1 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 and purchasing quality control.
4. Reagents
4.1 Purity of Reagents—Reagent-grade chemicals shall be
used in all tests. Unless otherwise indicated, it is intended that
all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society,
