ASTM D4563-02(2015)

Standard Test Method for Determination by Atomic Absorption Spectroscopy of Titanium Dioxide Content of Pigments Recovered From Whole Paint

SIGNIFICANCE AND USE
4.1 This test method may be used in quality control laboratories when the repeated analysis of titanium dioxide in similar paints may be required. Reagents and time are kept to a minimum when this test method is used in place of wet chemical analysis such as in Test Methods D1394. However, reproducibility and repeatability are not as good as in Test Methods D1394.
SCOPE
1.1 This test method covers the atomic absorption (AA) analysis of titanium dioxide content in pigments recovered from whole paint. It is applicable to quality control situations where the same type of product is repeatedly analyzed.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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. Specific hazard statements are given in Section 7.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Summary of Test Method
3.1 The specimen is prepared for analysis by ashing at 450°C followed by digestion with sulfuric acid and ammonium sulfate
as in Test Methods D1394. The titanium content is determined by atomic absorption spectroscopy using a specimen similar to that
previously analyzed by the Aluminum Reduction Method in Test Methods D1394.
3.2 By utilizing the pigment analyzed in Test Methods D1394 as an atomic absorption standard, several hundred TiO

determinations can be made. The AA technique is much faster than the technique in Test Methods D1394 for multiple
determinations and uses only acids. This keeps reagents and time to a minimum.
