ISO 29461标准规定了确定燃气轮机、压缩机和其他内燃机等旋转机械进气过滤系统中使用的颗粒空气过滤器性能的方法和程序。 该标准的ISO 29461-4规定了海洋和近海环境中使用的单个过滤元件和完整过滤系统的性能测试方法。本程序适用于每个滤芯额定流量高达8000 m3/h的滤芯和过滤系统。

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.
