NFPA (Fluid) T3.10.8.5 R1-1999 ✓ Most Recent [ Withdrawn ]

This standard specifies a method for verifying the collapse/burst rating of a hydraulic fluid power filter element, i.e., the capability of the filter element to withstand a designated differential pressure at the normal (intended direction of) flow. This test method will determine and verify element strength by means of pumping contaminated fluid through the element until collapse/burst occurs, or the maximum anticipated differential pressure is reached without element failure.
