Safety of machinery — Evaluation of the emission of airborne hazardous substances — Part 9: Decontamination index - First Edition
 N 29042-9

Annotation

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.
