precision_accuracy   Last year, a total of 40 laboratories from 14 different countries participated in an interlaboratory test to check proficiency according to European standard EN 13725/2003 organized by the company Odournet.Test criteria used in this comparison to assess the results were the precision under repeatability conditions r and accuracy A for 1-butanol of the laboratory according to EN 13725. There were 38 participants from Europe and 2 from Chile.

   A number of 34 laboratories in this study stated that they have been accredited for EN 13725 olfactometry measurements according to EN ISO/IEC 17025. The following table shows the list of participants.

A transposition of the German VDI 3880 for sampling on olfactometry in Chile is being discussed.

prnch3886The committee CL019 of Environment in the Chilean National Standardization Institute (INN) has begun a process to approve a new norm for sampling odours for dynamic olfactometry based on the existing German Norm VDI 3880. The new prNCh3386 Norma Muestreo estático para olfatometría (Standard Static Sampling for Olfactometry) will introduce several new requirements for a better representativeness of a sample. This way Chile will have a more advanced standard on odour sampling.

  Although many aspects of odour sampling will be included in the revised European standard EN 13725, the Chilean Normalization body has understood that there are still a few years left to see the new norm as a reference. In fact, there is a very detailed procedure for sampling odours in the already published as the German Norm Norm VDI 3880, Static sampling. olfactometry. Therefore there is a group of people led by the INN discussing about including several aspects of this standard on a new Chilean standard: the new NCh3386 Norma Muestreo estático para olfatometría.
