Description of 20/30384592 DC 2020ISOÂ 29461 specifies methods and procedures for determining the performance of particulate air filters used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. It applies to air filters with an efficiency of 85Â % or more for the MPPS (EPA and HEPA filters) which are tested according to ISOÂ 29463 part 1 to 5 and filters with a lower efficiency which are tested according to ISOÂ 16890 part 1 to 4. The procedures described in both, the ISOÂ 16890 series and the ISOÂ 29463 series, are applied and extended by this part of ISOÂ 29461 to air filters which operate at flow rates within the range 0,24Â m3/s (850Â m3/h, 500 ft3/min) up to 2,36Â m3/s (8500Â m3/h, 5000 ft3/min). This part of ISOÂ 29461 refers to static (barrier) filter systems but can also be applied to other filter types and systems in appropriate circumstances, for example to evaluate the initial efficiency of cleanable and surface loading filters. The performance results obtained in accordance with this part of ISOÂ 29461 cannot be quantitatively applied (by themselves) to predict performance in service with regard to efficiency and lifetime. Other factors influencing performance to be taken into account are described in the annexes.
