• Tên tiếng Anh / Title in English: Safety of machinery - Evaluation of the emission of airborne hazardous substances - Part 9: Pollutant concentration parameter, room method
• Phạm vi áp dụng / Scope of standard: 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.
