ISO 2942:2004 PDF

Scope: This part of GB/T 14041 specifies a test method that uses bubbling points to test the structural integrity of the filter element and determine the location of the maximum pore size of the filter material. This part of GB/T 14041 applies to filter elements used in hydraulic transmission systems. Structural integrity verification is used to determine the filter element's acceptability for future use or testing. The initial bubbling point can be determined through continuous structural integrity testing, but the test results cannot be used to infer the performance of the filter element such as filtration ratio, filtration efficiency or dirt holding capacity.
