旋转机械的进气过滤系统. 试验方法. 第1部分: 静态过滤器元件

[中文适用范围]： 本文件规定了用于确定旋转机械（例如固定式燃气轮机、压缩机和其他固定式内燃机）进气过滤系统中使用的颗粒空气过滤器静态性能的方法和程序。 它适用于根据 ISO 29463（所有部件）测试的 MPPS（EPA 和 HEPA 过滤器）效率为 85% 或更高的空气过滤器以及根据 ISO 16890（所有部件）测试的效率较低的过滤器。 ISO 16890（所有部分）和 ISO 29463（所有部分）中描述的程序均适用并通过本文件扩展至空气过滤器，其运行流量范围为 0.24 m3/s (850 m3/h) 至2.36 立方米/秒（8500 立方米/小时）。 静态过滤系统通常使用多级粗滤、细滤和可选的 EPA 或 HEPA 过滤元件来保护机械。 本文件的范围包括单个过滤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性能的方法，除非它们能够满足测试组件的资格标准。 尽管如此，精细过滤器的多级系统的累积过滤效率可以使用 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，但在适当的情况下也可以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（单独）定量地应用于预测在效率和寿命方面的使用性能。 [外文原描述]： 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 m 3 /s (850 m 3 /h) up to 2,36 m 3 /s (8 500 m 3 /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.
