5.PERFORMANCE TESTS
5.1 One sample should be used for the (preload) cycle tests, one sample for the static and dynamic tests, and one sample for the inductive kickback test. Every combination of handing, function (fail safe,fail secure, fail maintained), and voltage shall be tested separately as shown in the table below. It is acceptable to only test one sample for inductive kickback for each function regardless of handing or voltage. The table below is an example of the possible tests required. Sample requirements are allowed to be reduced at the discretion of the NRTL with documented justification.
5.2 Pre-Loaded Release Test (optional). When validating Pre-Load release capability, Pre-Load shall be applied during each cycle of the cycle test (5.3). Apply the selected force (from 5.2.3),perpendicular to the door in the direction of the door swing at a point 1 in. (25.4 mm) +/- 1/16 in. (1.6 mm) from the lock edge of the door and on the vertical centerline of the strike. With the applied load against the electric strike keeper, the strike shall release the latch in accordance with the conditions below. Breakage of the strike, failure to release, or failure to relock after release, constitutes failure of this test.
5.3 Cycle Test Test to the procedures described in UL 1034, section 39.1. In lieu of the wood door specified in UL 1034 section 26.4.2, the following test setup may be utilized. A mechanically operated test door, fixturing or panel that is 30-36”in width that simulates the operation of the electric strike as defined in UL1034, section 39.1. The height and thickness of test door or panel shall allow proper mounting of the electric strike being tested. The device shall be cycled with compatible hardware for the number of cycles specified. The test door shall be operated at a rate of not more than 17 cycles per minute. Where agreed upon by the manufacturer and lab, the test set up and cycle rate are allowed to be modified pending verification that all cycling aspects are maintained. One cycle consists of releasing
the locking mechanism (under pre-load if applicable), opening the door, allowing the door to close, and engaging the locking mechanism. Pre-Load force, when applicable, shall be applied per 5.2 on every cycle throughout the cycle test.Integral monitor switches, on models so equipped, shall be undergo the same cycles under manufacturer s recommended current and voltage load.The electric strike,including the monitor switch, shall function as intended at the end of the test.BHMA A156-31 pdf download.
