Scope
ISO 29042-4:2009 specifies a method based on a tracer technique for measuring the capture efficiency of an exhaust system installed on a machine. It is applicable to all types of test environment – test bench, room or field (see ISO 29042-1) – but is only applicable if the tracer shows aerodynamic behaviour comparable to that of the real pollutant.
