摘要：在TCO99、FCC、VDE和CISPR等EMC標準的有關(guān)內(nèi)容、特點及適應(yīng)范圍分析基礎(chǔ)上，給出了電磁波的頻譜、TCO99人體照射極限值、FCC標準及單位轉(zhuǎn)換、VDE傳導(dǎo)放射標準和輻射放射標準、CISPR-519PCC諧波電流限值（Ih/Il）百分比率表。并以信息設(shè)備GB9254傳導(dǎo)干擾標準的應(yīng)用為例，論述了標準選擇和產(chǎn)品測試注意事項，以便電子產(chǎn)品通過EMC指標測試，獲得EMC認證。 敘詞：電磁兼容； 電磁干擾；標準；指標測試 Abstract：In this article, the frequency chart of electromagnetic wave、the TCO99 human body projects light upon the extreme limit the value、FCC standard and its unit conversion、VDE conduct the emanation standard and radiate emanation standard、CISPR-519PCC harmonics current limit value(Ih/Il) percentage rate form are given based on analysis of concerning contents、characteristics and orientation scope of　TCO99、FCC、VDE and CISPR etc EMC standards. For the electronics product passing the EMC index sign test and acquiring the attestation, for a application example of conduct interference of information equipments GB9254, the standards choice and product test announcements are discussed.
