Railway applications - Energy measurement on board trains - Part 5: Conformity assessment
EN 50463-5 specifies the conformity assessment arrangements for newly manufactured EMS installed on a traction unit. This includes the integration conformity assessment and installation conformity assessment. In addition, EN 50463-5 also specifies the conformity assessment procedures for device and ancillary component replacement (e.g. due to damage in service), and periodic check to verify the EMS conformity assessment remains valid.

76 This document will supersede EN 50463-5:2017 and all of its amendments and corrigenda (if any).
77 prEN 50463-5:2025 includes the following significant technical changes with respect to EN 50463-5:2017:
78 — no technical changes introduced in document; only aligning with changes made in EN 50463-1
79 (commissioning and maintenance) and EN 50463-2 (explicitly adding verifications not possible on
80 equipment level).
81 This document has been prepared under a standardization request addressed to CENELEC by the
82 European Commission. The Standing Committee of the EFTA States subsequently approves these requests
83 for its Member States.
84 This document is Part 5 of EN 50463 series which consists of the following parts, under the common title
85 Railway applications — Energy measurement on board trains:
86 — Part 1: General;
87 — Part 2: Energy measuring;
88 — Part 3: Data handling;
89 — Part 4: Communication;
90 — Part 5: Conformity assessment.
91 This series of European Standards follows the functional guidelines description in EN ISO/IEC 17000:2004,
92 Annex A “Principles of conformity assessment”, tailored to the energy measurement system (EMS).
93 Introduction
94 The energy measurement system (EMS) provides measurement and data suitable for billing and may also
95 be used for energy management, e.g. energy saving.
96 This series of European Standards uses the functional approach to describe the EMS and on-ground data
97 collecting system (DCS). These functions are implemented in one or more physical devices. The user of this
98 Series of standards is free to choose the physical implementation arrangements.
99 a) Structure and main contents of EN 50463 series:
100 This series of European Standards is divided into five parts. The titles and brief descriptions of each part
101 are given below:
102 1) EN 50463-1 — General:
103 The scope of EN 50463-1 is the energy measurement system (EMS).
104 EN 50463-1 provides system level requirements for the complete EMS and common requirements
105 for all devices implementing one or more functions of the EMS.
106 2) EN 50463-2 — Energy measuring:
107 The scope of EN 50463-2 is the energy measurement function (EMF).
108 The EMF provides measurement of the consumed and regenerated active energy of a railway
109 traction unit. If the traction unit is designed for use on AC electric traction power supply systems the
110 EMF also provides measurement of reactive energy. The EMF provides the measured quantities via
111 an interface to the data handling system.
112 The EMF consists of the three functions: voltage measurement function, current measurement
113 function and energy calculation function. For each of these functions, accuracy classes are
114 specified and associated reference conditions are defined. EN 50463-2 also defines all specific
115 requirements for all functions of the EMF.
116 The voltage measurement function measur
