Abstract

This Expert Recommendation applies to all laboratories operating in Germany that carry out olfactometric measurements in accordance with DIN EN 13725. It is to be applied when determining the measurement uncertainty of olfactometric emission measurements. It replaces Clause 10.2 of DIN EN 13725, in particular with regard to the calculation of the measurement uncertainty. The paired measurements with n-butanol are omitted. In this context, further standard uncertainty components given by type-B-evaluations are also not taken into account. Method A6 "Paired measurements of two identical measuring systems" of DIN EN ISO 20988 for environmental odorant gas samples is to be applied unchanged.In the short term, the Expert Recommendation is intended to ensure a standardised calculation of measurement uncertainty that does not contradict DIN EN ISO 20988 and VDI 4219 for the transitional period until the revised standard VDI 3884 Part 1 is published.
