CISPR 12:2007+A1:2009 The limits in this International Standard are designed to provide protection for broadcast receivers in the frequency range of 30 MHz to 1 000 MHz when used in the residential environment. Compliance with this standard may not provide adequate protection for new types of radio transmissions or receivers used in the residential environment nearer than 10 m to the vehicle, boat or device. This standard applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from a) vehicles propelled by an internal combustion engine, electrical means or both; b) boats propelled by an internal combustion engine, electrical means or both. Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this standard; c) devices equipped with internal combustion engines. The following changes were made with respect to the previous edition: - deletion of narrowband / broadband determination; - general improvement of wording. This consolidated version consists of the sixth edition (2007) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
