(c) Participation Fee includes…..
   (1) Samples for the Testing
   (2) Shipping Charge of Samples
   (3) Final Report (electronic media; issued by UILI)
   (4) Certification/Diploma (printed paper; issued by UILI)
   (5) Shipping Charge of “Certification/Diploma”

6. Sample for Analysis

(a) Name of Testing Sample (printed on each label)
   (1) UILI-ILP Sample-2012 “Liquid-No.1”
   (2) UILI-ILP Sample-2012 “Liquid-No.2”

(b) Container of Testing Sample et al.
   (1) 100mL of sample is contained in 100mL volume plastic bottle.
   (2) There are 2 bottles per a set, a pair of different concentration for target compounds.

 
7. Target Compounds for Analysis

(a) Metals (6 items)

(b) Expected Concentration Range

(c) Samples have no “Assigned Value” such as “Reference Value” and/or “Certified Value” related for “True Value”.

8. Analytical Procedure

(a) Considering that the sample contains following ions, pre-treatment is required in this test.

(b) Analytical method is not limited (provider do not instruct). Participating laboratory can select the method for pre-treatment and instrumental measurement. Report a selected method No. from a table in “ATTACHMENT” which is attached at the end of this announcement.

9. Repot of Analytical Results

Independent analyses are requested to be carried out twice from sample preparation. Report the “mean value” of these 2 data (Original data before the calculation of “mean value” is not needed. Statistical values such as “standard deviation” are not needed). If you cannot analyze twice (e.g. in case of sample lack), reporting one data is acceptable.

(a) Round reporting values in significant 3 figures, according to ISO31-0:1992, Quantities and units - Part 0: General principles, Annex B (Guide to the rounding of numbers).

(b) Report should be done by a data set of “Liquid-No.1” and “Liquid-No.2”.

(c) A “non-full set result” is acceptable (e.g. In case that your laboratory prefers to report only on ”Cadmium”, report only the result of “Cadmium”).

(d) Method Reporting

1. Fill in the form “Result of Analysis” which is attached at the end of this announcement.
2. Report No. of analytical methods (“Pre-treatment” and “Measurement by Instrument”) referring to “ATTACHMENT” (table (A) and (B)) which is attached at the end of this announcement.
3. Use unit “μg/L” for reporting value.
4. Please meet the deadline; March 31, 2012.

10. Issue of the Final Report by UILI

(a) Final report will be issued on August 2012 by electronic media for participants.

(b)The following methods will be adopted for statistical analysis. The report will include these statistics.

1.  z-score: by ISO/IEC 17043 and related standards
2. Quartile Method (robust statistics method): by APLAC “T001”
3. Confidence Ellipse for Youden Plot” by ISO 13528

(c) As far as analytical methods were not designated for this test and median value is not always equal to “true value”, evaluation by statistic will be inadequate.

(d) A list of participating laboratories will be included in the report. The result of each laboratory will be shown by “laboratory identification numbers”. However, the relationship between the “laboratory identification numbers” and the “names of participating laboratories” will not be indicated. Your identification number will be informed in the letter attached, separated with the report.

11. Others

(a) This proficiency test is an International Proficiency Testing Program, a continual testing program scheduled by UILI.

(b) This proficiency test or the final reports on the test results is not aimed to assess the performance of the laboratories or relating personnel by the organizer of the test or third person. 

(c) Participants to this proficiency test will be issued a Certificate for Participation by UILI.
