ASTM E313

ASTM E313 is a standard developed by ASTM International that provides a method for measuring the color of materials, specifically their yellowness index. This index helps assess color quality by indicating how yellow or not a material appears, which is important in industries like plastics, textiles, and coatings. By using this standard, manufacturers can ensure consistent color quality in their products, which is crucial for meeting consumer expectations and ensuring product performance. In essence, ASTM E313 helps maintain color consistency and quality across various materials.
