The specimens were randomly placed in the test cabinet in the order shown in Table III to avoid any systematic error due to variations in the test conditions in different parts of the salt-spray cabinet.  The bolt-plate sets were supported on plastic racks at an angle of approximately 30° from the horizontal.
