本标准的全部技术内容为强制性。

本标准等同采用国际标准CISPR11:2003((工业、科学和医疗((ISM)射频设备电磁骚扰特性的限

值和测量方法))(英文版)。

本标准代替GB4824-2001《工业、科学和医疗(ISM)射频设备电磁骚扰特性的测量方法和限值》。

本标准与GB4824-2001相比，主要变化如下:

a)增加了“放电加工(EDM)设备”、“弧焊设备”及有关的术语、定义和限值。

b)增加了要求工科医设备制造厂、供应商在产品上用标签或在技术文件中提出警示，标明并解

释设备的组别和类别。对适用于工业环境中的A类设备，必须告知用户，在非工业环境中使

用该设备时，要达到电磁兼容可能有潜在的困难。(见第4章和5.1.2.1)

。)表“4在试验场测量时，2组B类设备电磁辐射骚扰限值”中，增加了平均值限值，并加了说明，

指出平均值限值仅适用于磁控管驱动的装置，当其在某些频率超过准峰值限值时，应采用平均

值检波器进行重新测量。

d)增加了“表5b在试验场测量时，A类EDM设备和弧焊设备的电磁辐射骚扰限值”

e)增加了模“拟手”的结构原理、附图(见6.2.5和图6)，以及正常工作时无接地的手提式设备用

模拟手进行测量的方法(见7.1.1),

f)增加了受试设备测量时对互连电缆的规定，一些特殊仪器设备在进行测量时不需要接信号线

(见6.4.1),

8)对弧焊设备，规定了在测量时用模拟的约定负载，由IEC60974-1。详细规定(见6.5.7).

h)增加了在30MHz--1GHz频段，可用替代辐射试验场进行辐射测量(见7.3).

D在附录A的2组设备中增加了“放电加工(EDM)设备”、“教育和培训用演示模型”、“高压特斯

拉变换器演示模型、皮带发电机等”。

与CISPR11:2003相比对于CISPR11;2003表1中的中心频率433.920MHz和915.000MHz,

由于我国不把它们指配给工科医设备使用，因此在本标准的表1中没有这两个频率。

本标准的附录C为规范性附录，附录A、附录B、附录D、附录E和附录F为资料性附录。
