German state government recommends Odournet GmbH proficiency test for EN13725 olfactometry

According to EN13725, laboratories applying the method of olfactometric measurement are requested to regularly participate in interlaboratory tests to demonstrate their competence in odour concentration analysis. Odournet GmbH in Kiel has now been recommended as inspection body for this interlaboratory test by the North Rhine-Westphalia State Agency for Nature, Environment and Consumer Protection (LANUV).

The International Comparison of Olfactometry (ICO) proficiency test under EN13725 is organised annually. The objective of the proficiency test is (1) the accuracy A determined for n-butanol and (2) the determination of the lab specific precision r. The calculation of both parameters is performed according to the annex D of the standard. In addition, participation in proficiency testing is a significant element of accreditation under ISO17025.

Odournet, being accredited for the organisation of the ICO under ISO17043, is proud to report that the North Rhine-Westphalia State Agency for Nature, Environment and Consumer Protection (LANUV) has now recommended the ICO organized by Odournet as a suitable proficiency test.

All ICO measurements are carried out as follows:

• Locally at the site of the participating laboratory;
• The odour samples are sent in pressured cans by Odournet GmbH;
• The measurements are carried out within a stated time window of 5 working days;
• Double blind procedure, to ensure maximum data confidentiality.

The next ICO is planned for June 2013.
