Application Summary AI generated
This standard specifies the test method for determining the gas permeability of daily-use pottery, including the principle, apparatus, sample preparation, and calculation procedures. It is applied in the quality inspection and production control of porous ceramic products such as unglazed pottery teapots, wine jars, and water jugs, where controlled gas exchange is a functional requirement. The method is used by manufacturers and testing laboratories to evaluate whether pottery meets specified permeability standards for food contact or liquid storage applications.
