Railway applications - Energy measurement on board trains - Part 2: Energy measuring
This European Standard covers the requirements applicable to the Energy Measurement Function (EMF) of an Energy Measurement System (EMS) for use on board traction units for measurement of energy supplied directly from/to the Contact Line system. This European Standard also gives requirements for the Current Measurement Function (e.g. current sensor), the Voltage Measurement Function (e.g. voltage sensor) and the Energy Calculation Function (e.g. energy meter). The Conformity Assessment arrangements for the Voltage Measurement Function, Current Measurement Function, the Energy Calculation Function and a complete Energy Measurement Function are also specified in this document. The standard has been developed taking into account that in some applications the EMF may be subjected to legal metrological control. All relevant metrological aspects are covered in this part.

Železniške naprave - Merjenje energije na vlaku - 2. del: Merjenje energije
Ta evropski standard zajema zahteve za funkcijo merjenja energije (EMF) sistema merjenja energije (EMS), ki se uporablja na vlakovnih kompozicijah za merjenje energije, dovajane neposredno iz sistema kontaktnega vodnika ali vanj. Ta evropski standard določa tudi zahteve za funkcijo merjenja toka (npr. tokovni senzor), funkcijo merjenja napetosti (npr. napetostni senzor) in funkcijo izračuna energije (npr. števec energije). V tem dokumentu so navedeni tudi načini ugotavljanja skladnosti funkcije merjenja napetosti, funkcije merjenja toka, funkcije izračuna energije in celotne funkcije merjenja energije. Standard je bil pripravljen ob upoštevanju dejstva, da se lahko pri nekaterih načinih uporabe funkcije merjena energije izvaja zakonit metrološki nadzor. Ta del zajema vse zadevne metrološke vidike.
