This document provides information about high pressure testing equipment and methods for testing mechanical integrity of filters. It describes that filters are tested to determine the pressure impulse of housing materials and constructions under conditions simulating engine lubrication system cyclic pressure pulsation. The test condition values should correspond to actual measurements from the intended engine application when such information is available. It also lists some key features of the testing equipment such as digital temperature indicators, pressure gauges, a stainless steel top plate with drainage pipe, and a safety enclosure with a transparent sheet.
