标准摘要
[中文适用范围]： IEC 62135 的这一部分适用于连接到额定电压高达 1 000 V acrms 的电源的电阻焊和相关工艺设备。该标准未定义安全要求。根据@进行类型测试并满足@本标准@要求的电阻焊接设备被视为符合所有应用。覆盖的频率范围为 0 Hz 至 400 GHz。电阻焊设备的本产品 EMC 标准优先于通用标准的所有方面，并且不需要或不需要额外的 EMC 测试。注 1：典型的相关工艺是电阻硬焊和软焊或通过与电阻焊设备相当的方法实现的电阻加热。注 2：仅针对部分频率范围规定了极限值。电阻焊设备分为A类和B类设备。 IEC 62135 的这一部分规定了 a) 与 CISPR 11 结合使用的测试方法，以确定射频 (RF) 发射； b) 谐波电流发射@电压波动和闪变的相关标准和测试方法。注 3：然而，当电阻焊设备距离接收天线（e）小于 30 m 时，本标准中的限制不能提供对无线电和电视接收干扰的全面保护。注 4：在特殊情况下，当高度敏感的设备在近距离使用时，有时会采用额外的缓解措施来进一步减少电磁辐射。 IEC 62135 的这一部分还定义了连续和瞬态传导和辐射干扰（包括静电放电）的抗扰度要求和测试方法。注 5：这些要求并不涵盖极其罕见的极端情况。 [外文原描述]： IEC 62135-2:2015 is applicable to equipment for resistance welding and allied processes which are connected to mains supplies with rated voltages up to 1 000 V a.c. r.m.s. This standard does not define safety requirements. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - update of the applicable limits related to the updated reference to CISPR 11; - exclusion of the use of narrow band relaxations for RF emission limits; - update of the applicable limits for harmonics and flicker related to the updated reference to IEC 61000-3-11 and IEC 61000-3-12; - update of the requirements for voltage dips related to the updated reference to IEC 61000-4-11 and IEC 61000-4-34; - inclusion of symbols to indicate the RF equipment class and restrictions for use; - inclusion of EM field immunity test for frequency from 1,4 GHz to 2,7 GHz; - inclusion of emission limits for class B resistance welding equipment magnetic fields between 150 kHz and 30 MHz.
