GB/T 1863-2008
Iron oxide pigments

GB/T 1863-2008 "Iron Oxide Pigments" specifies the technical requirements, test methods, and inspection rules for four major categories of pigments: iron oxide red, yellow, black, and brown. It covers indicators such as iron content, moisture, particle size, oil absorption, and pH value. The chemical composition is determined by titration or spectrometry, particle size is tested using a laser particle size analyzer, and oil absorption is measured with an analytical balance and grinding equipment. This standard provides a unified basis for quality control of iron oxide pigments used in fields such as coatings and building materials.
