摘　　要：电磁兼容性(EMC)风险评估旨在为EMC测试失效风险提供基于理想模型的分析和建议。从风险评估定义的赋值依据出发,分析其误差来源,并依据误差类型进行分类。对于不同类型的误差,根据赋值依据对其进行了数学分析及计算,并推导出对应的标准不确定度。结果显示,基于赋值依据的系统误差不确定度明显高于随机误差,因此在进行风险评估时要额外注意可能会产生系统误差的要素。Electromagnetic Compatibility(EMC)risk assessment is designed to provide ideal model-based analysis and recommendations for EMC test failure risk.Based on the assignment basis defined by risk assessment,the error sources are analyzed,and the error types are classified.For different types of errors,mathematical analysis and cal-culation are carried out according to the assignment basis,and the corresponding standard uncertainty is derived.The results show that the uncertainty of systematic error based on the basis of assignment is obviously higher than that of random error,so extra attention should be paid to the element points that may produce systematic error in risk assessment.
