EN 1093-4:1996 Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 4: Capture efficiency of an exhaust system - Tracer method (Incorporates Amendment A1: 2008)
This standard describes a method forThe measurement of the capture efficiency of an exhaust system installed on a machine.This method is based on a tracer technique and may be operated in all types of test environment (bench, room and field, see ENV 1093-1).This technique is applicable only ifThe tracer shows aerodynamic behaviour comparable withThe real pollutant (see 7.).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 c)The comparison of exhaust systems for machines of similar design; d)The ranking of exhaust systems according toTheir 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 toThe capture efficiency,
