Accelerated Physical Endurance
Test Procedure for Steel Doors
SDI 131-10
1 Purpose
The purpose of this test procedure is to provide
manufacturers with an accelerated method of
testing the performance of doors.
This test procedure will provide performance data
for comparative purposes and is not intended
to simulate field operating conditions. This test
will subject the product to more severe conditions
than those experienced in normal field
operation.
2 Apparatus and Equipment
The main testing structure shall be constructed
as shown in Figures 1 and 2. The structure shall
conform to the parts shown, except the opening
width and height are permitted to vary, allowing
the testing of various door sizes.
The cycling mechanism shall be positioned so that
the connecting arm is perpendicular to the stop
face of the door. It shall have a threaded swivel
connector that is attached to the door through
the lock preparation or by means of a bracket
mounted directly to the door face at the vertical
and horizontal location of the lock preparation.
The cycling mechanism shall have an operating
stroke so that the door lock edge will be opened
not less than 4 inches from the frame stop and
then returned to the closed position. The minimum
cycle rate shall be one cycle per second.
A mechanical or electronic counter shall be used
to record the cycles.
3 Preparation for Test
The door shall be hung in the frame on hinges
conforming to the most current edition of ANSI
A156.7-2009, “Template Hinge Dimensions”. The
hinges and their locations shall be noted on Form
1 of the report.
Care shall be taken to ensure the hinges are
properly applied to the door and frame, and
any required hinge fillers are in place. The initial
clearances between the door and frame shall be
recorded as part of the performance test report.
Silencers, weather strip or gasketing shall be
installed on the frame, and the stop face of the
door shall contact them.
4 Test Specimen
The test shall be performed on a 3'0" wide x
7'0" high nominal size door; although, other sizes
are permitted to be evaluated at the discretion
of the sponsor.
A detailed description of the door construction
shall be recorded as part of the test report.
This information shall cover all components as
well as applicable processes (such as welding,
bonding, etc.) used for attaching and connecting components.
5 Cycle Test
The duration of the test shall be 250,000 cycles
for Level C; 500,000 cycles for Level B; 1,000,000
cycles for Level A; or longer, if specified by the
test sponsor. A general inspection of the door
shall be made at 25,000 cycle intervals for the
first 100,000 cycles and at 50,000 cycles thereafter
until the completion of the required number
of cycles. The general inspection shall cover all
components readily accessible, such as face
skins, exposed hinge and/or lock edges, head
and sill closures, flush-closing channels, hinge
reinforcements, etc.
Additionally, the inspection
shall cover the welding, bonding, staking, mechanical
interlocking, etc., used to connect the
various door components.
The results shall be recorded on a standard performance
report “Door Test Form 1.”
TOP
When an independent third party organization is
employed to certify the overall performance of
the door design, they shall validate the initial,
mid-point, and final observations.
6 Twist Test
Any deterioration of the door construction as a
result of the cycle testing shall be determined
through a series of twist tests. These tests shall
occur prior to the onset of the cycle test and at
the end of the cycle test.
During the twist test, the hinge pins shall be
removed and the door moved to the twist test
fixture (if a separate fixture is used) and clamped
in place as shown in Figure 2.
If the same fixture is used for both the cycle
test and twist test, the hinge pins shall be removed
and the door clamped in place as shown
in Figure 2.
Pressures in 30-pound increments shall be applied
at the upper lock corner through the screw jack,
or equivalent device, and force gage in an area
as described in Figure 2. The deflection noted
on the dial indicator shall be plotted against
the load applied to the corner. A maximum 300
pounds pressure shall be applied. The pressure
shall then be reduced in 30-pound increments
and the deflection recorded on the report form.
A smooth curve drawn through the points shall
graphically demonstrate the reaction of the door.
Use “Performance Report – Door Test Form 2”
to graphically represent the deflections. Measurements for deflections shall be taken
one minute or less after the force has been
stabilized.
At the completion of each twist test, and prior
to the continuance of the cycle test, the hinges
shall be inspected and lubricated or replaced,
if necessary.
7 Acceptance Criteria
7.1 Doors shall not show any visible signs of
metal fatigue cracking, or deformation on the
edges or the door face.
7.2 Doors of either laminated or welded construction
shall not delaminate or have weld breakage
in excess of 10% of total bonded or welded
surface.
7.3 Top, bottom, or edge channels must remain
securely in place, with no signs of weld or bond
breakage.
7.4 Doors of stile and panel or stile and rail
construction shall not be misaligned.
7.5 Where visible seams are inherent in the door
design, no opening or spreading shall occur.
7.6 As a result of the twist test, the maximum
deflection shall not exceed 2-1/2" when loaded
to 300 lb for Level C doors. For Level B and A
doors, the maximum deflection shall not exceed
1-1/4" when loaded to 300 lb.
7.7 Permanent deflection measured within 5-
minutes after the force is removed shall not
exceed 1/8".
