         Directive 2006/42/EC

This European Standard specifies a room method for the measurement of the pollutant concentration parameter of a specified airborne hazardous substance from machines, located in a test room and operating the machines under defined conditions.This method can only be used for machines with a local exhaust ventilation with an air flow rate ³ 500 m3/h and machines without recirculated air.Measurement of the pollutant concentration parameter of a machine can serve for the:a)evaluation of the performance of a machine;b)evaluation of the improvement of the machine;c)comparison of machines within groups of machines with the same intended use (groups are defined by the function and materials processed);d)ranking of machines from the same group according to their pollutant concentration parameters;e)determination of the state of the art of machines with respect to their pollutant concentration parameter.
