CISPR 11. Industrial, scientific and medical (ISM) radio-frequency equipment - Electromagnetic disturbance characteristics - Limits and methods of measurement

The International Electrotechnical Commission (IEC). The International Special Committee on Radio Interference International Standard.Edition 4.1 2004-06, - 90 p.The limits and methods of measurement laid down in this International Standard apply to industrial, scientific and medical (ISM) equipment, and to electro-discharge machining (EDM) and arc welding equipment. The limits have been determined on a probabilistic basis taking into account the likelihood of interference. In cases of interference, additional provisions may be required.
Procedures are given for the measurement of radio-frequency disturbances and limits are laid down within the frequency range 9 kHz to 400 GHz.
Requirements for ISM lighting apparatus and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard.
Requirements for other types of lighting apparatus are covered in CISPR 15.
