Scope

This part of GB/T 25749 specifies the indoor method for measuring the pollutant concentration parameters of given harmful substances emitted by machines in the air when the machines located in the test room are operated under given conditions. This method is only applicable to machines with local exhaust ventilation air flow ≥ 500 m³/h and machines without air circulation. Measurement of pollutant concentration parameters of machines that can be used for: a) evaluation of machine performance; b) evaluation of machine improvements; c) comparison between groups of machines intended for the same purpose (such groups are defined by function and material processed ); d) Classify the machines in the same group according to the pollutant concentration parameters; e) Determine the technical level of the machines according to the pollutant concentration parameters.
