标准范围

IEC 62135-1:20 15适用于电阻焊和相关工艺的设备，包括可以手动或自动加载和/或启动的单个和多个焊接站。这第二版取消并取代了2008年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-4级污染的爬电距离不再有效（见表2）；-定义了II类设备的绝缘要求（见表3）；-介电测试电压插值限制下限改为220 V，并明确了控制和焊接电路的插值（见表4）；-根据当前版本的IEC 60085审查绝缘系统的最高温度（见表7）；-定义了端子的标记（见10.3）；-采用IEC 60664-1:20 07的表B.2代替上一版本中引用的表B.1值，对供电网络标称电压表进行了更改，以规定设备连接到接地和非接地系统。该变化影响了某些额定电源电压的爬电距离和间隙距离要求（见附录A）；-明确了故障条件下的接触电流测量程序（见6.4.4和附录C）；-定义焊接电路接触电流（见6.2.6）；-正常情况下的接触电流被澄清并移动以防止正常使用中的电击（见6.3.7）；-明确了加热试验条件（见7.1.1）；-改变了外表面温升限制（见7.3.2）。2016年2月更正的内容已纳入本副本。

IEC 62135-1:2015 applies to equipment for resistance welding and allied processes and includes single and multiple welding stations which may be manually or automatically loaded and/or started. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- creepage distances for pollution degree 4 are no longer valid (see Table 2);
- insulation requirements for Class II equipment are defined (see Table 3);
- dielectric test voltage interpolation restriction lower limit is changed to 220 V and interpolation for control and welding circuit is clarified (see Table 4);
- maximum temperature for insulation systems are reviewed in accordance with current edition of IEC 60085 (see Table 7);
- marking of terminals is defined (see 10.3);
- table for nominal voltages of supply networks is changed adopting Table B.2 of IEC 60664-1:2007 in place of the Table B.1 values referenced in the previous edition to provide for equipment to be connected to both earthed and unearthed systems. The change impacts the creepage and clearance distance requirements for some supply voltage ratings (see Annex A);
- touch current in fault condition are measurement procedures are clarified (see 6.4.4 and Annex C);
- welding circuit touch current is defined (see 6.2.6);
- touch current in normal condition are clarified and moved in protection against electric shock in normal service (see 6.3.7);
- heating test conditions are clarified (see 7.1.1);
- external surface temperature rise limitation is changed (see 7.3.2).The contents of the corrigendum of February 2016 have been included in this copy.
