Foreword

This Supplement to DIN 45673-8 has been prepared by Working Committee NA 001-03-15 AA (NALS/VDI C 15) Schwingungsminderung in der Umgebung von Verkehrswegen of the Normenausschuss Akustik, Lärmminderung und Schwingungstechnik (NALS) im DIN und VDI (Acoustics, Noise Control and Vibration Engineering Standards Committee in DIN and VDI). It contains (on CD-ROM) a form that can be used to systematically record the results of tests carried out in accordance with DIN 45673-8, thus increasing the comparability of technical data obtained with different products.

With this form, it is possible to compile the results of tests carried out at different times or by different testing institutes. On the first page of the form, the individual measurements of each responsible testing institute and the relevant test reports can be listed. The person responsible for compiling the results is to be named.

The form is provided as spreadsheet file in the form of an Excel workbook, comprising four worksheets, programmed using Excel 2010. The greyed out cells are edit boxes; some edit boxes have drop down lists from which information that conforms with the standard can be selected. The input information forms the basis for calculating dependent values and is taken over in all worksheets of the workbook. The required mean values and percentage changes are then automatically calculated from the input values. Graphics such as charts or diagrams can be embedded in the last worksheet of the form. The workbook (file name) is DIN_45673-8_ceRS.xlsx and is included in the attached CD-ROM. The file is write-protected (except for the edit boxes).

The test parameters specified in DIN 45673-8 are summarized in the form. Additional test parameters and results are to be included where necessary, depending on the use case and requirements of the user. To this end, additional worksheets can be added to the form included in this Supplement.
