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