标准范围

本文件描述了在最终用途安装配置中测量一般通风空气净化装置性能的程序。性能测量包括颗粒大小的去除效率和气流阻力。测试程序包括系统气流的定义和报告。该程序描述了一种计算环境空气微粒0.3？的方法微米至5.0运行中的空气处理系统中就地空气滤清器的上游和下游μm。该程序描述了颗粒计数器数据的缩减，以按颗粒大小计算去除效率。由于过滤器装置在设计和形状上有很大差异，因此包含了一个用于评估过滤器评估和系统评估现场适用性的协议。当评估的现场条件满足系统评估的最低标准时，也可以根据本程序进行系统性能评估。本文件还描述了测试设备的性能规范，并定义了计算和报告结果的程序。本文件不用于测量便携式或移动式室内空气净化器的性能，也不用于评估预期过滤效率为99%或以上的过滤器装置或在30%或以下当在0.4？处测量时微米。

This document describes a procedure for measuring the performance of general ventilation air cleaning devices in their end use installed configuration. The performance measurements include removal efficiency by particle size and the resistance to airflow. The test procedures include the definition and reporting of the system airflow.The procedure describes a method of counting ambient air particles of 0,3 μm to 5,0 μm upstream and downstream of the in-place air cleaner(s) in a functioning air handling system. The procedure describes the reduction of particle counter data to calculate removal efficiency by particle size.Since filter installations vary dramatically in design and shape, a protocol for evaluating the suitability of a site for filter evaluation and for system evaluation is included. When the evaluated site conditions meet the minimum criteria established for system evaluation, the performance evaluation of the system can also be performed according to this procedure.This document also describes performance specifications for the testing equipment and defines procedures for calculating and reporting the results. This document is not intended for measuring performance of portable or movable room air cleaners or for evaluation of filter installations with an expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 μm.
