ISO 2942:2004

Hydraulic fluid power — Filter elements — Verification of fabrication integrity and determination of the first bubble point

ISO 2942:2004 specifies a bubble-point test method applicable to filter elements used in hydraulic fluid power systems. It can be used either to verify the fabrication integrity of a filter element (by checking the absence of bubbles) or to permit the localization of the largest pore of the filter element by determining the first bubble point.
