43 1 Scope
44 This document applies to emission and immunity aspects of EMC for electrical and electronic
45 apparatus intended for use on railway rolling stock. EN 50121-3-2 applies for the integration of
46 apparatus on rolling stock.
47 The frequency range considered is from DC to 400 GHz. No measurements need to be performed at
48 frequencies where no requirement is specified.
49 This document takes into account the internal environment of the railway rolling stock and the external
50 environment of the railway, and interference to the apparatus from equipment such as hand-held radio-
51 transmitters.
52 The objective of this document is to define limits and test methods for electromagnetic emissions and
53 immunity test requirements in relation to conducted and radiated disturbances.
54 These limits and tests represent essential electromagnetic compatibility requirements.
55 Emission requirements have been selected so as to ensure that disturbances generated by the
56 apparatus operated normally on railway rolling stock do not exceed a level which could prevent other
57 apparatus from operating as intended. The emission limits given in this standard take precedence over
58 emission requirements for individual apparatus on board the rolling stock given in other standards.
59 Test requirements are specified for each port considered.
60 These specific provisions are to be used in conjunction with the general provisions in EN 50121-1.

109 4 Performance criteria
110 A functional description and a definition of the specific performance criteria of the equipment under test
111 (EUT), identifying acceptable degradation from normal performance during or as a consequence of
112 immunity testing, shall be provided in the equipment’s test specification and noted in the test report.
113 Acceptable degradation is a deviation of performance of the equipment that a reasonable user
114 accepts, when used as intended.
115 NOTE 1: Generally, the acceptable degradation of performance can be determined from an understanding of the
116 purpose of the equipment (e.g. from its functional description, documentation or common specifications for that
117 type of equipment).
118 The EUT’s specific performance criteria shall be consistent with the following general criteria for each
119 test as specified in Table 3 to Table 5:
120 Performance criterion A:
121 During and after the immunity test, the equipment shall;
122 — continue to operate and to remain controllable as intended within the identified acceptable
123 degradation from normal performance,
124 — not unintentionally change its operating state,
125 — not unintentionally change any critical stored data.
126 Performance criterion B:
127 The immunity test shall not result in;
128 — the mode of operation after the test being different to that at the beginning of the test,
129 — unintentional change to critical stored data
130 After the immunity test, the equipment shall operate as intended.
131 Performance criterion C:
132 The immunity test may result in loss of function, provided the function is self-recoverable, or can be
133 restored by the operation of the controls by the user. A reboot or re-start operation is allowed. The
134 immunity test shall not result in an unintentional change to critical stored data.
135 NOTE 2: Critical data includes data previously saved by the user.
