This study is a summary of the complex odor proficiency testing method using the air dilution sensory method conducted for the last 7 years. Results of the homogeneity and stability test were obtained from the measurement of the standard sample for identifying the range of measurable concentration so that the complex odor proficiency testing method was established through processing the manufactured standard sample and distribution method. Standard samples were prepared using a large Teflon bag after being homogeneously mixed inside a Teflon bag. Also, a distributing container was selected with a polyester aluminum bag in order to avoid samples of the best condition from being contaminated during transport as well as being exposed to invasive odor from a sampling bag. Test results revealed that the mixture of toluene and m-Xylene was most appropriate for this proficiency testing method to the homogeneity and stability of the testing method. In addition, DMS and DMDS were the optimized samples at the outlet area. As a result, the standard method was established to address the analysis quality management to the mixed odor inspection agencies in Korea.
