GB/T 3850-2015 "Impermeable sintered metal materials and hardmetals—Determination of density"

The GB/T 3850-2015 standard specifies a method for density determination of dense sintered metal materials and cemented carbide. The method calculates the density of the specimen by weighing it in an air neutralizing liquid. The standard describes in detail the preparation of the specimen, the accuracy of weighing, the requirements of the instruments and liquids used, and the steps to be followed in the measurement process to ensure the accuracy and Reliability of density determination. This standard applies to dense sintered metal materials and cemented carbide in the field of manufacturing, inspection and research.
