ECSS-E-ST-20中规定了EMC政策和一般系统要求。 该ECSS-E-ST-20-07标准涉及详细的系统要求（第4条），一般测试条件，系统级的验证要求以及子系统和设备级（第5条）的测试方法以及信息限制（附件A ）。 与ECSS-E-ST-20-06“航空电子充电”相关的ECSS-E-ST-20-06“充电控制”解决了ECSS-E-ST-20-07解决静电电磁效应时环境和车载飞船充电所引起的充电控制和风险放电。 ECSS-E-ST-20的附录A至C文件与ECSS相关的EMC活动E ST 20 07:EMC控制计划（附件A）定义了电磁效应验证计划（方案，程序，资源和组织）附件B）定义和规定了验证过程，分析和测试以及电磁效应验证报告（附件C）文件验证结果。 EMEVP和EMEVR是定制该标准的工具。 该标准可以针对符合ECSS-S-ST-00的空间项目的具体特征和限制

EMC policy and general system requirements are specified in ECSS-E-ST-20. This ECSS-E-ST-20-07 Standard addresses detailed system requirements (Clause 4), general test conditions, verification requirements at system level, and test methods at subsystem and equipment level (Clause 5) as well as informative limits (Annex A). Associated to this standard is ECSS-E-ST-20-06 “Spacecraft charging”, which addresses charging control and risks arising from environmental and vehicle-induced spacecraft charging when ECSS-E-ST-20-07 addresses electromagnetic effects of electrostatic discharges. Annexes A to C of ECSS-E-ST-20 document EMC activities related to ECSS E ST 20 07: the EMC Control Plan (Annex A) defines the approach, methods, procedures, resources, and organization, the Electromagnetic Effects Verification Plan (Annex B) defines and specifies the verification processes, analyses and tests, and the Electromagnetic Effects Verification Report (Annex C) document verification results. The EMEVP and the EMEVR are the vehicles for tailoring this standard. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
