ANSI A250 4:2001 pdf download.Test Procedure and Acceptance Criteria for一Physical Endurance for Steel Doors, Frames, Frame Anchors and Hardware Reinforcings.
The primary purpose of this procedure shall be to establish a standard method of testing the performance of a steel door mounted in a pressed steel or channel iron frame, installed with appropriate anchors, under conditions that might reasonably be considered an accelerated field operating condition.
The user of this performance standard must temper his usage with the knowledge that there are many variables that affect door performance, such as different hardware, anchors, glass and louver cutouts, field modification by parties other than the manufacturer, environmental factors, such as heat, cold, moisture, etc.

2 Apparatus and equipment
The apparatus and equipment used shall be the same when testing doors, frames or frame anchors. 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 to allow the testing of various door sizes. The test frame shall be anchored in such a manner as to insure rigidity.
The swinging mechanism shall be in two parts:
2.1 Door opener
The door opener shall be an air motor positioned at 65 to the plane of the door in its closed position. This will apply pressures on the crossbar of an exit device mounted on the test door. The actual contact point shall be set to push the door far enough to open it 60 ±50, and retract to allow the door closer to bring the door back into its original closed position and then begin the cycle again. See the specifications in figures 1 and 1A.
2.2 Hardware
The exit device, door closer and hinges used in testing shall be selected based on the man ufacturer’s recommendations for the testing level described in Swing Test Form 1. The manufacturer’s hardware part number shall be a part of the report. All hardware shall be applied to the door and frame with fasteners normally provided by the hardware manufacturer (for example, machine screws or sex bolts) in the location recommended by the door manufacturer. The hardware shall conform to the latest editions of American National Standards ANSI/BHMA Al 56.1, 3, and
4. The device shall be set to close the door at an approximate rate of 15 cycles per minute.
Note: Where the applicable BHMA Test Standards has been followed, this information shall be recorded as part of the test report.
3 Preparation for test
The door shall be hung in the frame on the hinges.ANSI A250 4 pdf download.
