Fire Performance BS 6387 Performance Requirements for Cables Required to Maintain Circuit Integrity under Fire Conditions.This standard details the following tests to categorise cables according to their fire withstand capabilities.
The cable is tested by exposure to gas burner flames while passing a current at its rated voltage.
Four survival categories are defined in the Performance Table below.
A new sample of cable is exposed to flames at 650°C for 15 minutes whilst passing a current at the rated voltage and then the spray is turned on to give exposure to both fire and water for a further 15 minutes.
The grade results are as follows:
The final requirement is mechanical shock damage. A fresh sample of cable is mounted on a backing panel in an S-bend and is exposed to flames whilst the backing panel is struck with a solid steel bar the same diameter as the cable under test every 30 seconds for 15 minutes.
Whilst the cable has been exposed to temperatures as defined in the Performance Table below.
Sunwin MI Cable can easily comply and withstand the most onerous categories of C, W and Z using one single Cable Sample
We carefully select, select good raw materials, to create high-quality wire and cable.
Give the user a rest assured.
