The Accredited Laboratory

System Outline

Order index is used at important scenes when administrative judgment and countermeasure against odor are required. It is important to keep expertise of people, establish necessary equipment and test room for accurate measurement of odor index. Our association has established inspection registration system of “accredited laboratory for olfactory measurement”, which shows certification of each laboratory since April 1993 and we have designated laboratories which satisfied technical standard, equipment standard and so on.

Current Number of Designated Laboratories (as of March 31st, 2010)

*Type 1

laboratory which has ability to calibrate olfactory measurement method and concentration of specified offensive odor substances properly:

4 laboratories

*Type 2

laboratory which has ability to calibrate olfactory measurement method properly:

64 laboratories

Criterion of Registration

With the rise of environmental preservation necessity, many of olfactory operators work for analyzing laboratories which conduct consigned measurement business and so on. Recently enterprises which work for ISO14001 acquisition have increased for their own environmental control.

 

Type 1  accredited laboratory
1. Olfactory operator : 3 or more operators
2. Panel : 6 or more panel members who have passed selection test (More than half panels should have experience for more than 2 years.)
3. Results of odor analysis : The number of samples by olfactory measurement method  should exceed 100 per year.
4. Analyzing (test) room : Sensory test room and odor-free room should be installed.
5. Equipment and apparatus : Necessary equipment and apparatus for olfactory measurement and specified offensive odor substances measurement  should be installed.
6. Technical standard : Odor index and odor emission intensity should be measured properly. (ambient and on-site samples)

7. Others : Calculation method for effluent odor index (triangular odor flask method) should be accepted, too.

 

Type 2 accredited laboratory

1. Ⅰ Olfactory operator : 2 or more operators

2. Panel : 6 or more panel members who have passed selection test

3. Ⅲ Analyzing room : Quiet room without a feel of odor

4. Equipment and apparatus : Necessary equipment and apparatus for olfactory measurement should be installed.

5. Technical standard : Odor index and odor emission rate should be measured properly.
