CISPR 11:20 24适用于工作在0 Hz至400 GHz频率范围内的工业、科学和医疗电气设备，以及设计用于产生和/或使用本地射频能量的家用和类似电器。本文件涵盖了与9 kHz至400 GHz频率范围内的射频（RF）干扰相关的发射要求。对于ITU无线电法规（2020）中定义含义内的ISM RF应用（参见定义3.1.18），本文件涵盖了与9 kHz至18 GHz频率范围内的射频干扰相关的发射要求。包含无线电发射/接收功能的ISM设备（具有无线电功能的主机设备）包括在本文件的范围内，参见附录F。然而，本文档中的发射要求并不旨在适用于ITU定义的来自无线电发射机的有意发射，包括其杂散发射。注1此排除仅适用于有意无线电发射机的发射。然而，组合发射，例如由ISM设备的无线电和非无线电子组件之间的互调产生的发射，不受此排除。 注2电磁炉的排放要求在CISPR 14-1中有规定。 在ITU无线电法规定义的ISM频段内工作的ISM RF照明设备和UV辐照器的要求包含在本文件中。 用于工业、科学和医疗应用的机器人属于本文件的范围。 示例焊接机器人、喷涂机器人、搬运机器人、加工机器人、装配机器人、医疗机器人、教育和实验机器人。IEC EMC专区提供了本文件范围内机器人的综合列表。 注3飞行机器人、家庭帮手机器人、玩具机器人和娱乐机器人是其他CISPR标准范围内的机器人示例。 其他CISPR产品和产品系列排放标准涵盖的设备不在本文件范围内。 本第七版取消并取代2015年发布的第六版、修正案1:20 16和修正案2:20 19。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: a)根据通用排放标准中给出的要求，对第1组设备在1 GHz以上频率范围内的辐射干扰引入限值；b)根据通用排放标准中给出的要求，引入有线网络端口上的传导干扰限值； c)对具有无线电发射/接收功能的设备提出要求； d)介绍各种类型机器人的定义； e)测量机器人时考虑一些特定条件，例如机器人的测量设置和操作模式。

CISPR 11:2024 applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use locally radio-frequency energy. This document covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (2020) (see Definition 3.1.18), this document covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. ISM equipment which incorporates radio transmit/receive functions (host equipment with radio functionality) is included in the scope of this document, see Annex F. However, the emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions.
NOTE 1 This exclusion only applies to emissions from the intentional radio transmitter. However, combination emissions, for example emissions resulting from intermodulation between the radio and the non-radio subassemblies of the ISM equipment, are not subject to this exclusion.
NOTE 2 Emission requirements for induction cooking appliances are specified in CISPR 14-1.
Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this document.
Robots used for industrial, scientific and medical applications are in the scope of this document.
EXAMPLE Welding robots, spraying robots, handling robots, processing robots, assembly robots, medical robots, education and experimental robots. A comprehensive list of robots in the scope of this document is given on the IEC EMC zone.
NOTE 3 Flying robots, domestic helper robots, toy robots and entertainment robots are examples of robots in the scope of other CISPR standards.
Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this document.
This seventh edition cancels and replaces the sixth edition published in 2015, Amendment 1:2016 and Amendment 2:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of limits for radiated disturbances in the frequency range above 1 GHz for group 1 equipment in line with the requirements given in the generic emission standards;
b) introduction of limits for conducted disturbances on the wired network port in line with the requirements given in the generic emission standards;
c) introduction of requirements for equipment which incorporates radio transmit/receive functions;
d) introduction of definitions for various types of robots;
e) consideration of some particular conditions when measuring robots, such as measurement setups and operating modes of robots.
