BS5308 Cables

BS5308: 1986 was officially withdrawn and replaced by BS EN 50288-7 on 1st April 2009. However as it will take some time for the new standard to become established as the norm, we will continue to offer cables to BS5308 where required by customers.

 

PAS5308

To many specifiers BS5308 is regarded as "the" standard for instrumentation cables and it's replacement by BS EN 50288-7 removes cable designs which are so well established that withdrawal of the standard could cause some difficulties. Cables manufactured exactly to BS5308 are not covered in the new BS EN 50288-7 Standard and so to avoid the complete loss of BS5308, it has been revised and reissued as PAS5308, a Publically Available Specification (PAS).  This does not carry the same weight as a BS5308 did previously but it allows for the technical content (with some additions/minor modifications) to be retained in a published document. 

 

 

BS5308 & BS EN 50288-7 Cables are designed to connect electrical instrumentation and communication systems in and around process plants in the oil, gas, petro-chemical industries, power generators and other process industries. They may also be used on intrinsically safe circuits. These cables are not for direct connection to the public mains supply. Armoured cables are suitable for direct burial.

These cables are also available with mica-taped conductors, in which case also comply with IEC 60331
