GB/T 5950-2008 "Method for Measurement of Whiteness of Building Materials and Non-metallic Mineral Products" specifies the method for measuring the whiteness of powder or block samples of building materials (such as white ceramics, cement, coatings) and non-metallic mineral products (such as kaolin, talcum powder) using a standard whiteness meter under specified geometric and optical conditions. This method calculates the whiteness value by measuring the light reflection characteristics of the sample, serving as an important indicator for evaluating its appearance and color.
