Customer information sheet 1
If you commission analyses from us without the accompanying sampling, we do not assume responsibility for the sampling. In this case the results for the sample apply as received. However, in accordance with the requirements of DIN EN ISO/IEC 17025:2018-03, we must check whether the sample is suitable for the commissioned analysis upon arrival at our laboratory. In this information sheet we inform you which requirements samples must meet in order to be suitable for analysis of specific parameters.
