GB/T 4472-2011 "Determination of density and relative density of chemical products" specifies the terms, definitions and determination methods for the determination of density and relative density of chemical products. This standard applies to the determination of density and relative density of solid, liquid and gaseous chemical products, ensuring the accuracy and comparability of measurement results. However, this standard does not apply to the determination of density and relative density of chemical products in special states, such as carbon black, open-cell foam rubber or plastics, etc. The standard also cites related documents such as GB/T 6682 "Specifications and test methods for water used in analytical laboratories" to ensure standardization and conformity in the measurement process.
