欧盟已于在2015年3月份颁布了新的EN 50121-x:系列标准，最新标准可以被使用的时间为05 Jan. 2016，老的标准停止使用的时间为05 Jan. 2018。该系列标准对整车厂要求有重大的改变。
| EN 50121-1:2015 | | Railway applications - Electromagnetic compatibility - Part 1: General | | 23680 | | This Part 1 of the European standards series EN 50121 outlines the structure and the content of the whole set. It specifies the performance criteria applicable to the whole standards series. Clause 5 provides information about the EMC management. This part alone is not sufficient to give presumption of conformity to the essential requirements of the EMC-Directive and is intended to be used in conjunction with other parts of this standard. Annex A describes the characteristics of the railway system which affect electromagnetic compatibility (EMC) behaviour. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions (e.g. fault conditions) and the induction effects of direct lightning strike. Emission limits at the railway system boundary do not apply to intentional transmitters within the railway system boundaries. Safety considerations are not covered by this set of standards. The biological effects of non-ionising radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here. | | Published

| EN 50121-2:2015 | | Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world | | 23681 | | This European Standard is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail system. It describes the measurement method to verify the emissions, and gives the cartography values of the fields most frequently encountered. This European standard specifies the emission limits of the whole railway system to the outside world. The emission parameters refer to the particular measuring points defined in Clause 5. These emissions should be assumed to exist at all points in the vertical planes which are 10 m from the centre lines of the outer electrified railway tracks, or 10 m from the fence of the substations. Also, the zones above and below the railway system may be affected by electromagnetic emissions and particular cases shall be considered individually. These specific provisions are to be used in conjunction with the general provisions in EN 50121 1. For existing railway lines, it is assumed that compliance with the emission requirements of EN 50121 3 1, EN 50121 3 2, EN 50121 4 and EN 50121 5 will ensure the compliance with the emission values given in this part. For newly build railway systems it is best practice to provide compliance to the emission limits given in this part of the standard (to be defined in the EMC plan according to EN 50121 1). | | Published

| EN 50121-3-2:2015 | | Railway applications - Electromagnetic compatibility - Part 3-2: Rolling stock - Apparatus | | 23683 | | This European Standard applies to emission and immunity aspects of EMC for electrical and electronic apparatus intended for use on railway rolling stock. EN 50121 3 2 applies for the integration of apparatus on rolling stock. The frequency range considered is from DC to 400 GHz. No measurements need to be performed at frequencies where no requirement is specified. The application of tests shall depend on the particular apparatus, its configuration, its ports, its technology and its operating conditions. This standard takes into account the internal environment of the railway rolling stock and the external environment of the railway, and interference to the apparatus from equipment such as hand-held radio-transmitters. If a port is intended to transmit or receive for the purpose of radio communication (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 corresponding EMC related standard for radio equipment. This standard does not apply to transient emissions when starting or stopping the apparatus. The objective of this standard is to define limits and test methods for electromagnetic emissions and immunity test requirements in relation to conducted and radiated disturbances. These limits and tests represent essential electromagnetic compatibility requirements. Emission requirements have been selected so as to ensure that disturbances generated by the apparatus operated normally on railway rolling stock do not exceed a level which could prevent other apparatus from operating as intended. The emission limits given in this standard take precedence over emission requirements for individual apparatus onboard the rolling stock given in other standards. Likewise, the immunity requirements have been selected so as to ensure an adequate level of immunity for rolling stock apparatus. The levels do not however cover all cases which may occur with an extremely low probability of occurrence in any location. Specific requirements which deviate from this standard shall be specified. Test requirements are specified for each port considered. These specific provisions are to be used in conjunction with the general provisions in EN 50121 1. | | Published
