What is BS EN 50288-9-2- Analogue and digital multi-element metallic cables about?
BS EN 50288-9-2 is a safety standard on multi-element metallic cables used in analogue and digital communication and control.
BS EN 50288-9-2 covers screened cables, characterised from 1 MHz up to 1 000 MHz, to be used to construct cords for use in cabling. The premises-specific cabling standards of the EN 50173 series reference the D1 requirements of BS EN 50288-9-2 for the cable used within cords of the “reference implementations” of those standards. The alternative D2 requirements of BS EN 50288-9-2 may be used to produce cords for other implementations and applications including the direct connection of equipment in data centres.
BS EN 50288-9-2 contains the electrical, mechanical, transmission and environmental performance characteristics and requirements of the cables when tested in accordance with the referenced test methods. BS EN 50288-9-2 should be read in conjunction with EN 50288-1, which contains the essential provisions for its application. The cables covered in BS EN 50288-9-2 are intended to operate with voltages and currents normally encountered in communication systems.
Note: These cables are not intended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains.
Who is BS EN 50288-9-2- Analogue and digital multi-element metallic cables for?
BS EN 50288-9-2 on multi-element metallic cables used in analogue and digital communication and control is relevant to:
- Manufacturers of multi-element metallic cables used in analogue and digital communication and control
- Manufacturers of screened cables and patch cord
- Electricians
- Testing authorities
- Data centre technicians
Why should you use BS EN 50288-9-2- Analogue and digital multi-element metallic cables?
A cable is considered screened when the cable core is covered by a continuous conductive layer forming part of the shielding and bonding system of the cabling system.
Screening of the cabling elements is applied in accordance with EN 50288-1:2013, 4.5. It is advised that when a braid is used the minimum braid coverage (for mechanical purposes) shall be 60%. BS EN 50288-9-2 specifies the tests that are applied to the completed cable.
Overall, BS EN 50288-9-2 is useful as it provides guidance on the sectional specification for screened cables characterized from 1 MHz up to 1000 MHz for work area, patch cord and data centre applications which can be helpful for your business.
