ISO 29461-4:2025 Scope
This document defines test methods for performance testing of individual filter elements and of the complete filtration system.1)
This procedure is intended for filter elements and filter systems which operate at flow rated up to 8 000 m3/h per filter element.
1) The filters will be loaded with ultra-fine salt particles of a size mostly sub micron during variable humidity to simulate real offshore and coastal conditions hence filters with an initial conditioned efficiency lower than 50 % for the ePM1 particles (filter class T7) are likely to underperform and would not be suited as a single stage filter.
