Fire hazard test

This series of tests are to check how cable trays and their accessories may contribute to propagating fire. They are only applicable to insulating or compound materials.

Test methods

There are two test types:

  • Fire hazard test: The device is subjected to an abnormal heat source similar to one that would be produced during an electrical fault, and must report a given inflammability. The test method is governed by IEC 60695-2-11, glow wire flammability test method.
  • Fire propagation: The objective of this test is to define the ability of trays to ignite, and if they do, if limited spread of fire takes place. The test method is governed by IEC 60695-11-2 by means of which a 1 kW flame is applied on an assembled set of the product.
