Gives a method for verification of 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 (i.e., intended direction of) flow.

This International Standard specifies a method for verifying the collapse/burst pressure rating of a hydraulic fluid power filter element, i.e. the capability of a filter element to withstand a designated differential pressure at the normal (i.e., intended direction of) flow, by means of pumping contaminated fluid through the filter element until either collapse/burst occurs or the maximum expected differential pressure is reached without element failure.
