    <title language="eng">Interlaboratory test 2023 on the method DIN EN 15188:2021-07 "Determination of the spontaneous ignition behaviour of dust accumulations" - Final report of results</title>
    <abstract language="eng">The test method DIN EN 15188:2021-07 “Determination of the spontaneous ignition behaviour of dust accumulations” is applied to characterize the self-ignition behaviour of combustible dusts. The experimental basis for describing the self-ignition behaviour of a given dust is the determination of the self-ignition temperatures (TSI) of differently-sized volumes of the dust sample by isoperibolic hot storage experiments (storage at constant oven temperatures) in commercially available ovens. The results measured this way reflect the dependence of the self-ignition temperatures on the volume of a dust accumulation.&#13;
&#13;
Several internal investigations in the past (e.g. interlaboratory tests in 2010-2011 and 2015-2016) have shown significant differences between the lab-specific results of hot storage tests of the former version of the revised DIN EN 15188:2021-07 (DIN EN 15188:2007). Therefore, an improvement of the test method DIN EN 15188:2007 was necessary.&#13;
&#13;
After a rather long and extensive series of various improvements (methodological modifications), the interlaboratory test in 2015-2016 demonstrated an acceptable reliability of the test method and a satisfactory measurement uncertainty if the modifications described in the interlaboratory test are taken into account. On the basis of this interlaboratory test in 2015, this subsequently led to a revision of the standard, whereby, in addition to the methodological improvements, the measurement uncertainty to be taken into account could now also be specified for the first time in this standard. The revised DIN EN 15188:2021-07 was published in 2021 and can now be applied by laboratories.&#13;
&#13;
This report provides the laboratory results of the first interlaboratory test 2023 on the revised method DIN EN 15188:2021-07 and summarizes the results of the assessment of laboratory performance.</abstract>

    <title language="eng">CEQAT-DGHS interlaboratory tests for chemical safety: Validation of laboratory test methods by determining the measurement uncertainty and probability of incorrect classification including so-called “Shark profiles”</title>
    <abstract language="eng">Laboratory test results are of vital importance for correctly classifying and labelling chemicals as “hazardous” as defined in the UN Globally Harmonized System (GHS) / EC CLP Regulation or as “dangerous goods” as defined in the UN Recommendations on the Transport of Dangerous Goods. Interlaboratory tests play a decisive role in assessing the reliability of laboratory test results. Interlaboratory tests performed over the last 10 years have examined different laboratory test methods. After analysing the results of these interlaboratory tests, the following conclusions can be drawn: &#13;
1. There is a need for improvement and validation for all laboratory test methods examined. &#13;
2. To avoid any discrepancy concerning the classification and labelling of chemicals, the use of validated laboratory test methods should be state of the art, with the results accompanied by the measurement uncertainty and (if applicable) the probability of incorrect classification. &#13;
&#13;
This paper addresses the probability of correct/incorrect classification (for example, as dangerous goods) on the basis of the measurement deviation obtained from interlaboratory tests performed by the Centre for quality assurance for testing of dangerous goods and hazardous substances (CEQAT-DGHS) to validate laboratory test methods. This paper outlines typical results (e.g. so-called “Shark profiles” – the probability of incorrect classification as a function of the true value estimated from interlaboratory test data) as well as general conclusions and steps to be taken to guarantee that laboratory test results are fit for purpose and of high quality.</abstract>
