GB/T 1707-2012 "Lithopone" applies to white pigments produced by calcining coprecipitates of zinc sulfide and barium sulfate, specifying product classification, requirements, test methods, and other contents for use in fields such as coatings, inks, rubber, and plastics. The determination of total zinc content is conducted using a potassium hexacyanoferrate titrator (arbitration method) and an EDTA titrator. Sample weighing is performed using an analytical balance with a precision of 0.1 mg, covering tests for indicators such as tinting strength, hiding power, and oil absorption.
