摘　　要：对设备或系统的电磁兼容(EMC)评估,通常依据行业或产品标准在其规定的EMC测试条件下进行,但实际应用中由于成本或配置受限等原因,无法做到标准的配置要求,该设备在相同等级的电磁干扰测试中的测试结果可能不一致,甚至出现异常故障甚至导致设备损坏。该文着重介绍了设备或系统出现不符合EMC标准即非标EMC测试的原因与测试方法,针对非标EMC干扰对电子设备的影响进行了技术分析,提出一系列适用于设备产品研发和EMC测试整改阶段的标准、非标EMC对策,使电子设备能在标准和非标EMC环境下都能具备较强的电磁兼容能力。The evaluation of EMC(Electromagnetic Compatibility)for equipment or systems should follow the requirement of the Trade Standards or Product Standards.However,in practical applications,when the standard EMC configuration cannot be met due to limitations such as cost or installation constraint,the EMC performance of this equipment or system in the same EMC test level maybe different,or malfunction even be damaged.This paper mainly focuses on the EMC test methods that cannot meet the EMC standards(shorted by non-standard EMC),give a technical analysis about the impact of non-standard EMC interference to equipment,and proposes a series of EMC design and countermeasures method applied with both standard and non-standard EMC in design and testing which can improve electronic equipment to have strong EMC performance in both standard and nonstandard EMC electromagnetic environments.
