ASTM D4563-02 (2022) Standard Test Method for Determination of Titanium Dioxide in Pigments Recovered from Whole Paints by Atomic Absorption Spectroscopy (AAS) provides a standardized method for the determination of titanium dioxide in pigments recovered from paints by atomic absorption spectroscopy (AAS). Titanium dioxide is a commonly used white pigment, and its content in paints and coatings directly affects the coverage and durability of the product. This method is suitable for recovered paints pigment samples, ensuring that its mass and conformity are assessed by accurate measurement of titanium dioxide content in pigments. This standard is important for environmental analysis, waste disposal, and quality control in the paints industry, helping companies ensure that their Coatings comply with relevant environmental protection and mass standards.
