This International Standard specifies the emission limits and test conditions for lifts, escalators and passenger conveyors permanently installed in buildings. NOTE These limits, however, might not provide full protection against disturbances caused by radio and television reception, when such equipment is used within distances given in Table 1. For conducted phenomena and harmonic distortion, this International Standard is applicable to equipment intended to be connected to low-voltage systems interfacing with the public supply at the low-voltage level. It is not applicable to equipment intended to be connected only to private low-voltage systems interfacing with the public supply only at the medium- or high-voltage level. Where the equipment is intended to be connected only to private systems, it is advisable that the manufacturer state this in the product documentation. Limits of interference within private systems can be negotiated between the affected parties.
