弧焊设备电磁兼容性要求的新国标即将出台

The New National Standard of Electromagnetic Compatibility Requirements of Arc Welding Equipment Will Be Issued

有关弧焊设备电磁兼容性要求的新国标已参照最新版IEC 60974-10:2007首次制定,比较了IEC 60974-10:2007与IEC 60974-10:2004两者在弧焊电源电磁发射限值、抗扰度要求和试验条件等方面的差异和要求,并分析其对弧焊电源电磁兼容测试的影响,以指导弧焊设备生产厂家应对电磁兼容强制要求。

According to IEC 60974-10： 2007, the new national standard of electromagnetic compatibility （EMC） requirements of arc welding equipment has been established first time. The article compares the main differences and requirements between IEC 60974-10：2007 and old IEC 60974-10：2004 including the limits of electromagnetic emission, the requirements of elec- tromagnetic immunity and the test conditions. It also analyzes their effects on the EMC tests for arc welding machine, and can nrovide the guidance to equipment manufacturers to deal with the EMC compulsory reauirements on arc welding machine.
