IEC 60601-2-25:2011适用于心电图仪的基本安全性和基本性能，这些心电图仪本身或作为医疗电气系统的一部分，用于产生用于诊断目的的心电图报告。打算在医院环境或医生办公室以外的极端或不受控制的环境条件下使用的设备，如救护车和航空运输，应符合本特定标准。附加标准可适用于用于这些使用环境的医疗电气设备。不包括在本特定标准范围内的有: a)医疗电气设备中提供心向量图回路的部分； b)IEC 60601-2-47涵盖的非用于获取用于诊断目的的心电图报告的动态心电图医用电气设备；c)IEC 60601-2-27涵盖的心脏监护仪，其不用于获取用于诊断目的的心电图报告。 第二版取消并取代了1993年出版的IEC 60601-2-25第一版和2003年出版的IEC 60601-2-51第一版。更新特定标准以参考通用标准的第三版提供了将IEC 60601-2-25和IEC 60601-2-51的第一版合并为一个标准的机会。进行了重新格式化和技术更改。IEC 60601-2-25的第二版构成了这两个标准的技术修订版。

IEC 60601-2-25:2011 applies to the basic safety and essential performance of electrocardiographs intended by themselves or as a part of a medical electrical system, for the production of electrocardiogram reports for diagnostic purposes. The equipment intended for use under extreme or uncontrolled environmental conditions outside the hospital environment or physician's office, such as in ambulances and air transport, shall comply with this particular standard. Additional standards may apply to Medical electrical equipment for those environments of use. Not included within the scope of this particular standard are:
a) the part of Medical electrical equipment that provides vectorcardiographic loops;
b) ambulatory electrocardiographic medical electrical equipment covered by IEC 60601-2-47 where not intended for obtaining electrocardiogram reports for diagnostic purposes;
c) cardiac monitors covered by IEC 60601-2-27 where not intended for obtaining electrocardiographic reports for diagnostic purposes.
This second edition cancels and replaces the first edition of IEC 60601-2-25, published in 1993 and the first edition of IEC 60601-2-51, published in 2003. Updating the particular standards to refer to the third edition of the general standard provided the opportunity to merge the first editions of IEC 60601-2-25 and IEC 60601-2-51 into one standard. Reformatting and technical changes were both made. This second edition of IEC 60601-2-25 constitutes a technical revision of both those standards.
