This draft standard contains the German version of the Draft European Standard prEN 50715:2021. It contains provisions for the statistical assessment of the measurements of the radio-frequency emission at a sample of equipment from series production and the conclusion to be drawn to the whole series in relation to the conformity with the requirements of the standard according to which the sample was measured. The statistical assessment methods which are proposed for application and are associated with varying effort are described in clause 4. The additional subdivision in different frequency subranges that should be done during the application of the statistical assessment method on the basis of the non central t-distribution for particular products like household appliances, electric tools, lighting equipment and ISM equipment is specified in clause 5. The provisions contained in this draft for the statistical assessment of the measurements at a sample of equipment from series production are still contained as information in particular Harmonized European Standards, that adopt relevant standards of CISPR. However, it was decided at European level to delete this information from the relevant Harmonized European Standards and to produce in return an European Guidance Document, which should not be listed in the Official Journal of the European Union. This draft now serves for the purpose of the creation of this Guidance Document.
