8. Scope The ISO 29461 series specifies methods and procedures to determine the performance of particulate air filters used in air intake filter systems for rotary machinery such as gas turbines, compressors and other internal combustion engines. The ISO 29461-3 of the standard specifies a method and procedure to test the mechanical integrity (“Burst Test”) of individual filter elements up to an abnormal final test pressure drop of maximum 6250 Pa. Any other customer defined final pressure drop up to a maximum of 8000 Pa shall be reported as variation from the standard. It is within the liability of the user to define the maximum possible value (lower or higher) for a certain application and to define the burst strength requirements for this test procedure. As the pressure drops under typical operating conditions are on a much lower level, it is not intended to specify a final pressure drop for any application within this procedure. This procedure is intended for all types of filter elements (e.g. V-bank cassette filters or filter cartridges) used in the final stage(s) of an Air Intake Filter Systems for Rotary Machinery in various environmental conditions, as e.g. in marine applications. These filters are operating at flow rates within the range of 0,25 m³/s (900 m³/h) up to 2,23 m³/s (8000 m³/h), no matter if it is used in a static or pulse cleaned air intake system.
