| Resumen: | ISO 29461-3 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. 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. The Burst Test itself is considered as an independent procedure to evaluate the stability of a filter element to resist a defined high pressure drop without collapsing, losing or releasing any parts of its construction into the downstream or reducing its filtration efficiency. This part of the standard does not describe a standardizes method for measuring the fractional or gravimetric efficiency. It is recommended to test the efficiency of the filter element according part 1 or an another appropriate method (e. g. ISO 29463). The performance results obtained in accordance with this standard cannot be quantitatively applied (by themselves) to predict performance in real use. The test procedure does not include methods for the direct measurement of the performance of entire systems as installed, e. g. systems with use of multiple stages of coarse and fine filter elements. |
