ISO 29042-4:2009规定了一种基于示踪技术的方法,用于测量安装在机器上的排气系统的捕获效率。它适用于所有类型的试验环境——试验台、试验室或现场(见ISO 29042-1)——但仅当示踪剂显示出与实际污染物相当的空气动力学行为时才适用。
ISO 29042-4:2009 specifies a method based on a tracer technique for measuring the capture efficiency of an exhaust system installed on a machine. It is applicable to all types of test environment — test bench, room or field (see ISO 29042-1) — but is only applicable if the tracer shows aerodynamic behaviour comparable to that of the real pollutant.
