5、reword The main task of ASD-STAN Technical Committees is to prepare EN Standards, in exceptional circumstances however, the publication of Technical Report of one of the following types may be proposed: Type 1, the subject is still under technical development requiring wider exposure; Type 2, a Tech

6、nical Committee has collected data of a different kind from that which is normally published as a European Standard. The Electrical Domain decided to publish this document in the form of a Technical Report of type 2 in order to facilitate the updating of this document. Page 4 TR 4654-010:09-2014 1 S
