In the UL standard, 20 minutes is the lowest rating and most common choice for a wood fire door. Though people think 20 minutes is a pretty short time for a fire emergency, it does save much more people than it’s regarded.

 

The door is usually used for interior living rooms while rarely being used for entrance door. When a fire emergency happens, smoke is always much more dangerous than fire itself cause in the most of fire emergencies people get killed by smoke instead of burned. A 20 minutes UL labeled wood fire door is tested in a 1000flame for 20 minutes, whereafter the inspectors will use a water torch to damp down the fire. This process will last around 5-10 minutes and the test will succeed only if the door is not broken or fallen down. So when search for 20 minutes wood fire door, please take a look at the certificate of supplier whether they have passed positive pressure test.
