Fire testing explained:

BS EN Standards

  • BS EN 1366-4 Fire resistance test for service installations. Linear joint seals.
  • BS EN 1634-1 Fire resistance test for doors, shutters and openable windows.
  • BS476-22 Fire resistance of non-loadbearing elements of construction. Building materials and structures.

How does EU Fire testing compare with BS fire rating testing ?

Both Standards use thermocouples The European fire test standards (BS EN) all use the more advanced plate thermocouple technology to measure the air temperature, BS476 series of tests use the wire thermocouple option.

BS EN (British Standard European Norm) 1366-4 could be considered a more vigorous test because it is tested to a more consistent recorded temperature.

FF197 is Tested to BS EN 1366-4, BS EN 1634-1 and meets BS476-20 & 22
