IEC 61010-031:2022规定了用于电气测试和测量的手持式和手持式探头组件及其相关附件的安全要求。这些探头组件用于零件与电气测试和测量设备之间的非接触或直接电连接。它们可以固定在设备上，也可以是设备的可拆卸附件。 根据IEC指南104，它具有团体安全出版物的地位。 本第三版取消并取代2015年发布的第二版，以及修正案1:20 18。IEC 61010-031是一个独立的标准。与上一版相比，此版本包括以下重大技术变更: 范围已经变得简洁。第2版范围中的一般信息已移至新的第4条。因此，第2版第4条至第8条已重新编号。删除了第2版第9条； 在第2条中，规范性引用已注明日期，并增加了新的规范性引用； 在3.1.4中，修改了探头尖端的定义； 在4.1中，高压和低压探头组件之间不再有任何区别。C型探针组件已与B型探针组件合并； 在4.1 d）中，“开尔文”探头已作为新的E型和新的图5添加到探头组件列表中； 在4.1 e)中，不与导体电连接的电压测量探头已作为新的F型和新的图6添加到探头组件列表中； 在4.2.1中，火势蔓延不再被视为危险； 删除了第2版第4.4.2.5款；删除了第2版第4.4.4.3款； 在5.4.4.1中，已经考虑了间距和阻抗； 在6.1.1中，允许带有标记的探针尖端的可拆卸部件； 在6.1.5中，测量类别要标记的电压是交流线路到零线或直流电压； 在7.4.2中，未配对连接器的要求修改如下: 对表2进行了修改和扩展， 定义了20kV以上连接器间隙的计算方法， 爬电距离已与间隙一致； 在7.4.3.1和7.4.3.5中，增加了带可伸缩套筒的IP2X探头尖端的要求； 在7.4.3.2中，探头尖端现在适用于非接触式探头组件； 在7.5.2.3.2中，修改了表5的值； 在7.6.2中，间隙的电压测试在没有湿度预处理的情况下进行；第2版第10条刚度试验的预处理已移至9.2； 删除了第2版第11.1款； 在13.2中增加了E型探头组件的例外。允许带有标记的探针尖端的可拆卸部分； 图F.1已修改； 增加了附件G，用于确定表2的清除量； 增加了附录H，涵盖了普通主电源系统的线路到中线电压。

IEC 61010-031:2022 specifies safety requirements for hand-held and hand-manipulated probe assemblies for electrical test and measurement, and their related accessories. These probe assemblies are for non-contact or direct electrical connection between a part and electrical test and measurement equipment. They can be fixed to the equipment or be detachable accessories for the equipment.

It has the status of a group safety publication in accordance with IEC Guide 104.

This third edition cancels and replaces the second edition published in 2015, and Amendment 1:2018. IEC 61010-031 is a stand-alone standard. This edition includes the following significant technical changes with respect to the previous edition:
