Safety of machinery — Evaluation of the emission of airborne hazardous substances — Part 9: Decontamination index
|Publication Date:||15 January 2011|
|ICS Code (Safety of machinery):||13.110|
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.
