This ensures that the doors are made with the best material and they will provide protection to the people when there is fire. All the different components of the door will work together and then provide safety to your building. The company tests all the components separately with the help of a testing agency and label them properly. As per the testing, the rating of the fire door is maintained.

Testing Standards

Fire doors are tested according to the specific standards.

  • NFPA 252, Methods of check Door Assemblies
  • UL 10B, Fire Tests of Door Assemblies (neutral or negative pressure)
  • UL 10C, Positive Fire Pressure Tests of Door Assemblies

Testing Procedure

Then the testing will be done by facing one side of the door with the heat that would be similar to if there is spread of fire. During this, the upper part of the door will be under very small pressure as this will happen when the fire will occur. The door will be tested from both sides to see how well it can serve its main purpose. When the testing is going on the strength and stability will also be checked.

After this, the hose stream test is conducted. In this, the water is put on the door from 20 feet away. Then the fire doors are put under a temperature rise to ensure the person can exit from the building in different conditions. Temperature rise rating is then conducted which includes:

  • 250 degrees F
  • 450 degrees F
  • 650 degrees

The F indicates the maximum rise in the temperature. Then the smoke test is conducted to see if it prevents the smoke from spreading to other corridors and room.


Once the testing is done the fire doors will receive a rating.
