Annex
A (informative) Simplified calculation of the
random component of the uncertainty on C3(95%)
Gives a method to measure the capture efficiency of an exhaust system installed on a machine. It is based on a tracer technique and may be operated in all types of test environment (bench, room and field, as in ENV 1093-1). Applies only if the tracer shows aerodynamic behaviour comparable with the real pollutant.
