本文件规定了测定旋转机械（如固定式燃气轮机、压缩机和其他固定式内燃机）进气过滤系统中使用的微粒空气过滤器静态性能的方法和程序。它适用于效率为85？根据ISO测试的MPP（EPA和HEPA过滤器）的百分比或更高？29463（所有部件）和根据ISO测试的效率较低的过滤器？16890（所有零件）。ISO中描述的程序？16890（所有零件）和ISO？29463（所有部分）通过本文件应用并扩展到流量在0，24？立方米/秒（850？立方米/小时）高达2.36？m3/s（8？500？m3/h）。 静态过滤系统通常使用多级粗、细和可选的EPA或HEPA过滤元件来保护机器。本文件的范围包括单个过滤器元件的性能测试方法。它不包括直接测量安装在使用中的整个系统的性能的方法，除非它们能够满足测试组件的资格标准。然而，精细过滤器的多级系统的累积过滤效率可以通过使用ISO 16890-1中描述的方法来计算。 本文件涉及静态（屏障）过滤器系统，但也可以在适当的情况下应用于其他过滤器类型和系统，例如评估可清洁和表面负载过滤器的初始效率。 根据本文件获得的性能结果不能定量应用（本身）来预测关于效率和寿命的服务性能。

This document specifies methods and procedures for determining the static 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 85？% or more for the MPPS (EPA and HEPA filters) which are tested according to ISO？29463 (all parts) and filters with a lower efficiency which are tested according to ISO？16890 (all parts). The procedures described in both ISO？16890 (all parts) and ISO？29463 (all parts) are applied and extended by this document to air filters which operate at flow rates within the range 0,24？m³/s (850？m³/h) up to 2,36？m³/s (8？500？m³/h). Static filter systems normally use multiple stages of coarse, fine and optional EPA or HEPA filter elements to protect the machinery. The scope of this document includes methods for performance testing of individual filter elements. It does not include methods for the direct measurement of the performance of entire systems as installed in service except in cases where they can meet the qualification criteria for the test assembly. Nevertheless, cumulative filter efficiencies of multistage systems of fine filters can be calculated by using the methods described in ISO 16890-1. This document 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 document cannot be quantitatively applied (by themselves) to predict performance in service with regard to efficiency and lifetime.
