Hi

I have a door which I believe to be fire proof but cannot prove it. Is there anyway to test it?

The fire test is a destruction test and little is left of the door afterwards which would be of little use to you. The manufacturer designs a fire door then has three tested using a special furnace to see how long they would hold back a fire. The test company provides the manufacturer with a test report on how the doors behaved in the test and how long it held back the fire. Then it is assumed all doors constructed to that specification would behave similarly in a fire. The only way to prove the fire resistance of a fire door is the documentation provided by the manufacturer.

You can get a fire door assessor who could give you a report on his/her opinion how the door would behave in a fire which could be acceptable to an enforcement officer.
