scope:

This part of ISO 29042 specifies a test bench method for the measurement of the emission rate of a given airborne hazardous substance from a machine using a test bench under specified machine operating conditions.

The measurement of the emission rates of a given pollutant emitted from machines can serve for

evaluation of the performance of a machine,

evaluation of the reduction of pollutant emissions of a machine,

comparison of machines within groups of machines having the same intended use (as defined by the function and materials processed),

ranking of machines from the same group according to their emission rates, and

determination of the state-of-the-art of machines with respect to their emission rates.

This part of ISO 29042 is not applicable to machinery manufactured before the date of its publication.
