Fire Rated Cables

BRE Global specialises in working with clients to help assess and develop the performance of cabling products. Cables alone are very rarely the source of a fire, but can add the potential for spread of flame and to the fire load. We provide a complete range of cable testing and approvals for the Construction, Transport, Marine, Aviation and Fire Detection market. Further information can be seen below or in the leaflet which can be downloaded from the right hand side of this page.

 

Buildings of any generation are full of different kinds of cables. Each one of them represents a potential hidden danger capable of providing a full fire load that can spread fire rapidly throughout a building. This underlines the importance of ensuring cables are tested and approved to the appropriate standards. BRE Global provides the cable industry with an authoritative and independent testing service, and through LPCB is able to offer third party approval.

LPCB approved cable is tested and certified to a full range of applicable specifications and standards. Our approvals process includes assessment of the manufacturer's ISO 9001 or Factory Production Control systems to ensure that the products meet and continue to meet our quality criteria in addition to annual product audit testing.  

Fire rated cables are split into two categories, section 8.1 fire resistant cables and section 8.2 fire retardant cables.

Both types of cables are required to perform differently in the event of a fire.

Fire resistant cables are designed such that in the event of a fire they maintain circuit integrity

Fire retardant cables are designed such that in the event of a fire they limit the generation and spread of fire and smoke.

CE Marking

The product standard EN 50575 for power, control and communication cables was cited in the OJ on 10 July 2015, marking the start of CE marking being possible for these products from 1 December 2015. By 1 July 2017, CE marking will become mandatory for all such products placed on the market in Europe.

As a Notified Body for a wide range of construction products covered by the CPR, and a UKAS accredited laboratory for conducting the tests needed to demonstrate compliance, BRE Global is able to provide manufacturers of these products with a professional and efficient service in support of their CE marking requirements.
