The scope of this proficiency testing is the evaluation of the performance of laboratories for the determination of the metals in sewage sludge and similar matrices.
Interlaboratory proficiency testing organized in accordance with the standard ISO/IEC 17043:2010 - Conformity assessment — General requirements for proficiency testing.

ANALYSIS
The test sample should be analysed under the same conditions and with the same procedures used for the routine samples in the laboratory including the quality control procedures.
For each measurand shall be reported one result.
ADDITIONAL RESULTS: Each participant can submit up to 5 results* for the same analyte, thus obtaining an evaluation of laboratory performance for different operators, instruments and/or test methods (e.g. operator 1/operator 2, instrument A/instrument B, etc..).

*: Only one result submitted by the laboratory will be included in the statistical treatment of data for the calculation of the Assigned Value and statistics of data of the analyte, to avoid that a single laboratory has a different statistical weight, depending on the number of its submitted results. The additional results are evaluated by assigning z-score values, using the Assigned Value and the Standard Deviation for Proficiency Assessment obtained from statistical treatment.
