摘要
在TCO99、FCC、VDE和CISPR等EMI标准有关内容、特点及适应范围分析基础上。给出了电磁波的频谱、TCO99人体照射极限值、FCC标准及单位转换、VDE传导放射标准和辐射放射标准、CISPR-519 PCC谐波电流限值(Ih/I1)百分比等表。并以信息设备GB9254传导干扰标准的应用为例,论述了标准选择和产品测试注意事项,以便电子产品通过EMI指标测试,获得EMI认证。
Based on analyzing related contents, characteristics and adaptive ranges of TCO99, FCC, VDE and CISPR etc EMI (Electro magnetism interference) standards, the frequency chart of electromagnetic wave, the extreme limit the value of TCO99 human body projects light, FCC standard and its unit conversion, the emanation standard of VDE conduct and radiate emanation standard, the limit value (Ih/Il) percentage rate form of CISPR-519PCC harmonics current were given out. Taking application of conduct interference of information equipments GB9254 as an example, the announcements of standards selecting and product test are discussed, for the electronics product to pass the EMI index sign test and obtain EMI attestation.
