EN 1093-11:2001 Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 11: Decontamination index (Incorporates Amendment A1: 2008)
This standard describes a method for the measurement of the decontamination index of pollution 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 4.2 of EN 1093-1: 1998 " Safety of machinery-Evaluation of the emission of airborne hazardous substances-Part 1: Selection of test methods") and can be operated in room or field environments. It should be observed that during the test; especially during the shutdown or the removal of the pollution 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. Warning:This standard does not deal with the protective measures required to control these risks. Measurement of the decontamination index of pollution control system can serve for the: evaluation of the performance of a pollution control system of a machine; evaluation of the improvement of a pollution control system; comparison of pollution control systems for machines of similar design; ranking of pollution control systems according to their decontamination efficiency; determination of the air flow rate in the case of an exhaust system to achieve a given level; determination of the state of the art of pollution control systems for machines with respect to the decontamination efficiency.
