ANSI/BHMA and UL Compliance Requirements for Sliding Doors
(Sheet 2 of 3)
To ensure that a sliding door operates in accordance with UL 325 entrapment protection criteria the following must
be established:
• Manual opening force (sliding doors without breakout) or breakout force with power on or off must be less
then 50 lbf (222.4 N).
• Closing force must be less than 30 lbf (133.4 N).
• A closing sliding door must not develop kinetic energy in excess of 2.5 ft-lbf (3.39 J). This is achieved by proper
setting of the closing speed. See section entitled “Closing Speed”.
• Maximum recommended door weight:
• Dura-Glide 5000 Series = 150 lbs (70 kg) per panel.
• Dura-Glide/Dura-Guard/Dura-Storm and similar 2000/3000 Series = 220 lbs (100 kg) per panel.
• IS10000/Double Diamond and similar Industrial Series = 300 lbs (90 kg) per panel
Closing Speed
Closing speed is measured over a travel distance of 2 or 3 feet. On smaller bi-part doors there may only be
2 feet of movement before the door system enters close-check (latch check). The time measurement should
start once the door has achieved closing speed, usually 6 inches from full open. Mark this point on the floor
with tape or other object. Measure from this point 2 or 3 feet toward the closed position and mark the next
point. Use a stopwatch to measure the time it takes for the sliding panel to travel this distance during
normal closing cycles. Make sure the door system is not braking or entering close-check during the
measurement. Repeat the measurement 3 times and use the average value. The allowed time for a
sliding panel to cover this distance during the closing cycle is given in the table below.
