適用范圍：This standard describes a method for the measurement of the capture efficiency of an exhaust systeminstalled on a machine. This method is based on a tracer technique and may be operated in all types of testenvironment (bench, room and field, see ENV 1093-1).This technique is applicable only if the tracer shows aerodynamic behaviour comparable with the real pollutant(see 7.1.1).The measurement of the capture efficiency of an exhaust system can serve for:a) The evaluation of the performance of an exhaust system of a machine;b) The evaluation of the improvement of an exhaust system of exhaust systems for machines of similar design; OC) The comparisond) The ranking of exhaust systems according to their capture efficiency;e) The determination of the air flow rate of an exhaust system to achieve a given level of capture efficiency;f) The determination of the state of the art of exhaust systems for machines with respect to the capture efficiency,
