Scope: The method specified in this standard is called the bubble test method, which is applicable to the determination of the pore diameter of permeable sintered metal materials (filters, porous bearings, porous electrodes and other components with communicating holes) by the "bubble test" method. Bubble test is a test method for quality control of porous metal materials, which is not suitable for measuring the grade of porous metal materials, nor can it accurately determine the pore size and pore size distribution of porous metal materials.
