This supplement to DIN 45673-5 contains a test form allowing to systematically summarize the results of the tests in accordance with DIN 45673-5 thus achieving simple comparability of the technical data of various products. It is possible to summarize the results of tests carried out at different times or in different test institutes. For this it is possible to indicate the test institutes responsible for the individual measurements and the associated test reports on the first page of the test form. The test form is provided as a table calculation file, in fact as a workbook with four worksheets programmed using Excel 2010. The required average values and the percentage changes automatically result from the individual values entered. The workbook is called DIN 45673-5 USM.xlsx and is contained on the attached CD.
