Scope: WARNING - It should be observed that during the test, especially during the shutdown or the removal of the pollutant control system, the concentration of hazardous substances, if present, can reach levels which are liable to incur a risk to the health of the operators or other occupants present in the room. This part of ISO 29042 does not deal with the protective measures required to control these risks. This part of ISO 29042 specifies a method for the measurement of the decontamination index of pollutant control systems, e.g. capture devices including local exhaust ventilation, water spray systems and, when appropriate, separation equipment installed on a machine. This method uses the real pollutant (see ISO 29042-1:2008, 4.2) and can be operated in room or field environments. Measurement of the decontamination index of a pollutant control system can serve for the: a) evaluation of the performance of a pollutant control system of a machine; b) evaluation of the improvement of a pollutant control system; c) comparison of pollutant control systems for machines of similar design; d) ranking of pollutant control systems according to their decontamination efficiency; e) determination of the air flow rate in the case of an exhaust system to achieve a given level; f) determination of the state of the art of pollutant control systems for machines with respect to the decontamination efficiency.
