BS 8491:2008 describes a method for assessment of the fire integrity of large diameter power cables for use as components for smoke and heat control systems as given in BS 7346-6, and certain other active fire safety systems. It is applicable to cables of rated voltage not exceeding 600/1 000 V and of overall diameter greater than 20 mm.

The test method in BS 8491:2008 includes subjecting the cable under test to radiation via direct impingement corresponding to a constant temperature attack of 842 °C, to direct mechanical impacts corresponding to a force of approximately 10 N, and to direct application of a water jet simulating a water fire fighting jet. The test method given in this standard includes three different test durations to allow testing of cables intended for different applications.

BS 8491:2008 contains:

  • Normative references
  • Terms and definitions
  • Test chamber 
  • Apparatus 
  • Verification procedure for the source of heat 
  • Test specimens 
  • Test procedure 
  • Test report

It is emphasized that fire tests do not assess a fire hazard, nor can the results of fire tests alone guarantee safety. They only provide information to assist in the assessment of the suitability of a cable for a given application.
