CHAPTER 1 - INTRODUCTION
technically competent in relation to requirements of EMC for the application of PDS's. For
economical reasons, the interested parties should guarantee essential requirements of EMC
protection, for the specific installation, by choosing adequate categories of emission, thanks
to in situ measurements of the actual conditions and thanks to the exchange of technical
specifications.
