UL 10C Test Lab

UL 10C — Positive Pressure Fire Tests of Door Assemblies

Fire doors are vital for the safety of personnel and property, able to block the fire spread up to a few hours. Fire door manufacturers will need to meet certain requirements to comply with codes and sell their products to end-users.

VTEC can perform UL10C testing to ensure your fire doors meet industry standards. Our test can be used for doors that are swinging, have lights and panels or are made of various materials.

UL 10C Test Methods for Fire Doors

UL 10C is a positive pressure test that assesses the performance of fire doors, specifically evaluating its ability to retain its secure assembly during the test. VTEC's fire door testing involves exposing the fire door to a fire that is a particular temperature for a predetermined amount of time. After the time is up, a fire hose stream will be applied to the fire doors. We will pass the door sample if it stays in the opening throughout both tests.

Fire Endurance Test

The fire test is controlled using a furnace that is large enough to hold the door sample. Inside the furnace is burners that are heat controlled, so the exposure to the door sample is uniform. The higher the flame temperature, the longer the sample is exposed.

In addition, we will also record the temperature of the unexposed surface to ensure it meets those requirements. We will place a minimum of three thermocouples in each 16 square foot area of the door and take readings every minute up to 30 minutes. The furnace pressure will also be measured using a pressure probe placed 40 inches above the sill, taking readings every minute.

Hose Stream Test

The hose stream test starts within 1.5 minutes of the completion of the fire endurance test. We will direct a hose stream to the door smoothly and steadily, making sure the water impacts every part of the door. When this pattern is complete, we will do the same in reverse.
