EN 1093-11:2001+A1:2008 4 Introduction This is a type B standard as specified in EN 1070. This standard is a part of EN 1093. Part 1 “ Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 1: Selection of test methods” of this standard presents a selection of different methods for the evaluation of the emission of airborne hazardous substances from machines. 1 Scope 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 decontamina-tion efficiency. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

EN 1093-11:2001+A1:2008 5 3 Terms and definitions For the purposes of this European Standard the definitions of EN 1070 and the following definition applies: 3.1 decontamination index IA the average of the ratios, obtained at a number of specified locations in the surroundings, of the ambient air quality improvement1) to the real pollutant mean concentration with the pollution control system not in operation. Corrections can be necessary to take into account of air pollution caused by other operations ("the background level") When particle size distribution is determined at the same time as pollutant concentration, a decontamination index for each size fraction can be determined (see for example EN 481 “ Workplace atmospheres - Size fraction definitions for measurement of airborne particles”). 4 Principle The principle of this measurement method consists in determining the decontamination index as defined in clause 3, the concentrations being measured at predetermined points around the machinery under inspection and in interpreting the value of this index, taking into account its range of variation and the influencing factors. 5 Determination of concentration measurement points The measurement points will have been
