1 Preliminärrapport för provningsjämförelse 6- Stockholm, 9 mars 6 Ag, Al, As, B, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Si, Sn, Sr, Tl, U, V, Zn och Cr6 Proverna i denna omgång var ett spikat recipient vatten (Del A), ett spikat kommunalt avloppsvatten (Del B) och en syntetisk lösning (del C). I preliminärrapporten är resultaten redovisade i figur- och tabellform här följer några förklaringar för tabellrubrikerna: Mean Stdev Range CV% n medelvärde, konsensus standardavvikelse max min variationskoefficient antal värden i de statistiska beräkningarna uteslutna resultat (outliers, mindre-än värden) Youdendiagram Analysresultaten representeras av värdepar Sample + Sample. Talparens placering visar ifall resultaten innehåller systematiska eller slumpmässiga avvikelser. Ett cirkelformat spridningsmönster indikerar en slumpmässig fördelning utan påtagliga systematiska fel. Är spridningsmönstret däremot samlat utefter 5 linjen är materialet behäftat med systematiska avvikelser. Histogram (eller frekvensdiagram) Hela värdeintervallet är uppdelade i ett antal del-intervall. Stapelhöjden motsvarar antalet mätvärden i del-intervallet. En normal fördelning av det statistiska materialet är jämn och symmetrisk med högsta antalet mätvärden i närheten av medelvärdet. En asymmetrisk fördelning eller flera tydliga maxima tyder på komplikationer som kan bero metoder, homogenitet eller dylikt. Kriterier för beräkning av z-scores i denna rapport För parametrar med minst sex godkända resultat beräknas z-score om proverna bedöms vara homogena och stabila m.a.p. den aktuella parametern. För parametrar med fyra eller fem godkända resultat beräknas z-score om CV% (standardavvikelse /medelvärde) är mindre än % och det finns högst ett outlier. Mindre-än värden och uppenbara rapporteringsmissar räknas inte som outliers. För parametrar som inte uppfyller villkoren presenteras grundläggande statistik, deltagarnas resultat, samt Youdendiagram utan konfidensintervall. Vänligen, meddela oss om du upptäcker misstag vi kan ha gjort i preliminärrapporten så vi kan rätta till dem i slutrapporten. Slutrapporten beräknas vara klar senast vecka 5.

2 Preliminary Report for Proficiency Test 6- The samples in this test round were a spiked recipient water (Part A), a spiked municipal wastewater (Part B), and a synthetic solution (Part C). Results in the preliminary report are shown only in tables and charts. Explanations for the abbreviations used in the table heads and translations for some key words: Mean Stdev Range CV% n average, consensus standard deviation max min coefficient of variation number of values used in the statistical calculations excluded values (outliers, less-than values) Stockholm, 9 March 6 Ag, Al, As, B, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, Se, Si, Sn, Sr, Tl, U, V, Zn and Cr6 Youden plots The results are represented as value pairs where Sample is plotted against Sample. The position of the value pairs reveals both systematic and random errors. Data scattered circularly around the intersection of the means are randomly distributed with no specific systematic errors. Data distributed along the 5 axis indicate the presence of systematic errors. Histograms (or frequency diagrams) The result range is divided into equal intervals along the x-axis with each bar representing the number of results in that interval. A normal statistical material is characterised by an even, symmetrical distribution with the majority of data centred around the mean. An asymmetric distribution or more than one obvious maximum indicates complications, for example with the methods or homogeneity. Criteria for the calculation of z-scores in this report For parameters with at least six acceptable results, z-scores are calculated if the samples are homogenous and stabile with respect to that parameter. For parameters with four or five acceptable results, and no more than one outlier, z-scores are calculated if the CV% (standard deviation/mean) is less than %. Less-than values and obvious clerical errors are not counted as outliers. No z-scores are calculated for parameters that do not fulfil the above conditions. Only the basic statistics, results of the participants and the Youden plot (without the confidence interval) are presented. Kindly inform us of errors we may have made in the preliminary report so we can correct them in the final report. A final report can be expected by April 5.

Standard Methods; SS-EN ISO 8:6 CR6-XX Other method. Observera! Proverna för Cr6 analys utgörs av syntetiska lösningar som är homogena och stabila. Det åsatta värdet för respektive prov är därför lika med den beräknade halten. För beräkning av z-scores är standardavvikelsen satt till 5% utifrån osäkerheten hos den beräknade halten (5%) plus precisionsdata i SS-EN ISO 8:6 (reproducerbarhets standardavvikelse max ca %). Please note! The samples for Cr6 analysis are synthetic solutions that are homogenous and stabile. The assigned value for each sample is therefore the calculated concentration. For the calculation of z-scores the assigned standard deviation is set at 5% based on the uncertainty of the calculated concentration (5%) plus precision data i SS-EN ISO 8:6 (reproducibility standard deviation max ca %).
