Fabrication Integrity – Bubble Test ISO 2942-2004
Product overview:
The Fabrication Integrity and First Bubble Point Test Rig for Filter Element is used 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.
Verification of the fabrication integrity defines the acceptability of the filter elements further use or testing. Auto Parts Test Equipment
The first bubble point is established through continuation of the fabrication integrity test. It is under no circumstances a functional characteristic of a filter element; in particular, it can not be used for extrapolation to the concepts of filtration rating, efficiency or retention capacity and should be used for information only.
Test Principle:
Install the tested filter element in the test container clean designated test liquid manually. The filter element is submerged in the test liquid, the filter element keeps rotating automatically, and the set air pressure is automatically increased during the test. Manually record the corresponding pressure value and bubbling point location, and input the computer to automatically generate a test report.
Standard:
The fabrication integrity and first bubble point test rig for filter element meet the standard of ISO 2942-2004, GB/T 14041.1-2007.
Test object:
Filter element used in hydraulic fluid power systems. Auto Parts Test Equipment
