Description of 20/30395648 DC 2020This document covers multi-element cables suitable for connecting instruments and control systems for analogue or digital signal transmission used in industrial processes carried out in commercial and industrial premises including cables that could be specified for use in Automated Infrastructure Management applications. They could be screened and optionally incorporate armouring and/or moisture or environmental protection layers. The cables are expected to have a mechanically robust construction and electrical transmission handling properties. The electrical, mechanical, transmission and environmental performance characteristics of the cables, related to their reference test methods are detailed in this specification. Cables covered by this document have maximum rated voltages of 300 V or 500 V a.c. Multi-element cables for use in analogue, digital and control circuits are not designed to be used for power supply or to be connected directly to mains electricity supply or other low impedance sources. NOTE These cables are expected to be installed in accordance with the applicable local and national regulations. According to Annex 1 of mandate M/443 EN, depending upon the installation and application these cables might not necessarily fall under the regulation of EN 50575. Cables intended to have circuit integrity in a fire are covered by this document. There could be occasions when cables are required to have higher operating temperature ratings than those provided by using materials specified by the EN 50290 series. Suitable alternative materials are under consideration.
