Hydraulic fluid power. Filter elements. Determination of resistance to flow fatigue using particulate contaminant1 Scope This International Standard specifies a method for determining the resistance of a hydraulic filter element to flow fatigue after it has been loaded with particulate contaminant and subjected to a uniform varying flow rate and predetermined maximum element differential pressure. It establishes a uniform method for verifying the ability of a filter element to withstand the flexing caused by cyclic differential pressures induced by a variable

The main changes with respect to the previous edition are listed below:

Service companies

lightweight

which extends the life of a sewage system and reduces the need for costly dig-ups

This test method describes the modifications to EN 16523-1 necessary to test against gaseous chemicals that can be collected by liquid or gaseous collecting media

Requirements are given for the materials and dimensions of the components and for protective finishes

It also specifies the applicable tolerances corresponding to the above‐mentioned tests

This International Standard facilitates the application of ISO 5169 relating to the presentation of lubrication instructions for machine tools

There is greater flexibility in the requirements for processes

This also helps in determining the electrical characteristics of these thyristors

with practical guidelines on design
