The International Electrotechnical Committee has released an amendment to CISPR 11 – the radio-frequency EMC standard for industrial, scientific and medical 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 consolidated version consists of the 2009 fifth edition and a 2010 amendment.This standard covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in frequency ranges where limits are specified in Clause 6.For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations, this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz.Requirements for ISM RF lighting apparatus and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard.Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard.View a preview of this standard from the IEC.
