CAN/CSA-CEI/IEC CISPR 11:04 (R2013)

This National Standard of Canada is equivalent to International Standard CEI/IEC CISPR 11:2003. 1 General 1.1 Scope and object The limits and methods of measurement laid down in this International Standard apply to industrial, scientific and medical (ISM) equipment as defined in Clause 2, and to electrodischarge machining (EDM) and arc welding equipment. NOTE 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 operating in the ISM frequency bands of 915 MHz (only allowed in region 2 as defined by the ITU Radio Regulations), 2,45 GHz and 5,8 GHz are contained in this standard. Requirements for other types of lighting apparatus are covered in CISPR 15.
