摘　　要：判定待测设备是否符合发射限值时,必须考虑测量仪器的不确定度。基础标准CISPR 16-4-2中描述了EMI测量需要考虑的不确定度的影响。CISPR 16-4-2第2版修正案2于2018年发布,相对上一版本,新的要求随之生效。介绍了CISPR产品标准的实施情况以及重大的技术变化。Measurement instrumentation uncertainty shall be taken into account when determining compliance or non-compliance with an emission limit.The corresponding uncertainty contributions to be considered for EMI measurements are described in the basic standard CISPR 16-4-2.With the publication of the 2nd Amendment to Edition 2 of CISPR 16-4-2 in 2018 new requirements became effective compared with the previous edition.The current status of implementation in CISPR product standards and the significant technical changes are presented.
