Hydraulic fluid power. Filter elements. Verification of fabrication integrity and determination of the first bubble point Ingestion-build-141043 PAS 156 sets out theThis document specifies a bubble point test method applicable to filter elements used in hydraulic fluid power systems. It can be used both to verify the fabrication integrity of a filter element (by checking the absence of bubbles) and to permit the localization of the largest pore of the filter element by determining the first bubble point. NOTE Verification of fabrication integrity is used to define the acceptability of the filter elements for
