ASTM D4563-02(2022) PDF

Overview

ASTM D4563-02(2022) is the established standard test method for determining the titanium dioxide content in pigments recovered from whole paint using atomic absorption spectroscopy (AA). Developed by ASTM International, this method is designed to support quality control laboratories in industries where the analysis of titanium dioxide (TiO₂) in similar paint products is routinely required. By utilizing atomic absorption, the method offers an expedited alternative to traditional wet chemical analysis, minimizing both reagent use and testing time without significantly compromising on accuracy for repetitive analyses.

Key Topics

• Test Method: This standard describes the process for preparing and analyzing pigment samples from whole paints using atomic absorption spectroscopy to determine their TiO₂ content.
• Scope of Use: Primarily intended for quality control scenarios involving repetitive testing of products with similar compositions, such as manufacturing batches of paints and coatings.
• Sample Preparation: The protocol involves ashing the paint sample at high temperature, digesting it with acids, and then analyzing it by AA spectroscopy.
• Measurement and Calculations: The result is expressed in mass percent of titanium dioxide, utilizing only SI units.
• Precision and Repeatability: The method is optimized for efficiency but acknowledges that repeatability and reproducibility may not match classical wet chemical analysis standards, such as those outlined in ASTM D1394.
• Safety and Compliance: Users must establish appropriate safety, health, and environmental practices when handling hazardous reagents and comply with local regulations.

Applications

ASTM D4563-02(2022) is especially valuable in the following contexts:

• Quality Control in Paint Manufacturing: Enables manufacturers and laboratories to reliably and quickly determine the titanium dioxide content in paint pigments, ensuring product consistency and regulatory compliance.
