20、1-4:2016 (E) 4 Introduction This European Standard has been prepared in the form of a Product Standard. It defines the immunity and emission test requirements for apparatus defined in the scope in relation to the electromagnetic disturbances likely to be experienced in the railway. In particular, th
21、e test requirements represent the essential electromagnetic immunity requirements and have been selected to ensure an adequate level of immunity for apparatus installed on the railway locations. Test requirements are specified for each port considered. Safety considerations are not covered by this s
22、tandard. In specific situations, where the level of disturbances may exceed the levels considered in this standard, e.g. at a special location or where a hand-held transmitter is used in very close proximity to an apparatus, special mitigation measures may have to be employed. BS EN 50121-4:2016 EN
23、50121-4:2016 (E) 5 1 Scope This European Standard applies to signalling and telecommunication apparatus that is installed inside the railway environment. Signalling and telecommunication apparatus mounted in vehicles is covered by EN 50121-3-2:2016, signalling and telecommunication apparatus install
24、ed inside the substation and connected to substation equipment is covered by EN 50121-5:2016. This European Standard specifies limits for emission and immunity and provides performance criteria for signalling and telecommunications (S apparatus inside the 3 m zone; ports of apparatus inside the 10 m
25、 zone with connection inside the 3 m zone; ports of apparatus inside the 10 m zone with cable length 30 m. Other apparatus not covered by at least one of these given cases should be in compliance with EN 61000-6-2. If a port is intended to transmit or receive for the purpose of radio communication (
26、intentional radiators, e.g. transponder systems), then the radiated emission requirement in this standard are not intended to be applicable to the intentional transmission from a radio-transmitter as defined by the ITU. Immunity limits do not apply in the exclusion bands as defined in the correspond
27、ing EMC related standard for radio equipment. The standard does not specify basic personal safety requirements for apparatus such as protection against electric shock, unsafe operation, insulation co-ordination and related dielectric tests. The requirements were developed for and are applicable to t
28、his set of apparatus when operating under normal conditions. Fault conditions of the apparatus have not been taken into account. The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified. For products in the scope of E
29、N 61000-3-2, EN 61000-3-3, EN 61000-3-11 or EN 61000-3-12 the requirements of those standards also apply. These specific provisions are to be used in conjunction with the general provisions in EN 50121-1:2016. The immunity and emission levels do not of themselves guarantee that the integration of ap
30、paratus will necessarily be satisfactory. The standard cannot cover all the possible configurations of the apparatus, but the test levels are sufficient to achieve satisfactory EMC in the majority of cases. 2 Normative references The following documents, in whole or in part, are normatively referenc
