ISO 29462:2013描述了在最终使用安装配置中测量通用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。本程序描述了一种计算运行中的空气处理系统中就地空气滤清器上游和下游0.3μm至5.0μm环境空气颗粒的方法。该程序描述了颗粒计数器数据的减少，以计算颗粒大小的去除效率。由于过滤器安装在设计和形状上有很大的不同，因此包括了一个用于评估过滤器评估和系统评估场地适用性的协议。当评估的现场条件满足为系统评估制定的最低标准时，也可以根据本程序对系统进行性能评估。ISO 29462:2013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。本国际标准不适用于测量便携式或移动式室内空气净化器的性能，也不适用于在0.4μm下测量时，预期过滤效率等于或高于99%，或等于或低于30%的过滤器装置的评估。
ISO 29462:2013 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 procedures for test 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.ISO 29462:2013 also describes performance specifications for the testing equipment and defines procedures for calculating and reporting the results. This International Standard is not intended for measuring performance of portable or movable room air cleaners or for evaluation of filter installations with and expected filtration efficiency at or above 99 % or at or below 30 % when measured at 0,4 μm.
