WDMA T.M. 7-14 Test Method for Determining the Physical Endurance of Wood Doors & Associated Hardware Connections under Accelerated Operating Conditions tests the performance of a wood door as it swings in its opening. The test is designed to accelerate the actual operating conditions. This test method will not determine the useful life of doors in service as a result of the data obtained during this test. It will however, indicate what the effects of hard impacts upon closing (slamming) and cycling will be on the door and door hardware connections. It will provide useful data for designers, specifiers, and manufacturers in making judgments on the ability of the door assembly to maintain serviceability under actual operating conditions.
