appearance, function, and serviceability and prevent potential hazard to personnel or their clothing.
Performance. Each cabinet shall comply with the following requirements. Failure to comply with these requirements shall be cause for rejection.
Assembly test. A completely knocked-down cabinet shall be easily set up using common hand tools. Instructions shall be provided.
Door hinge test. This test shall be conducted on completely assembled cabinets. With the cabinet in an upright position, a 150 pound test load shall be suspended from the door (each door of double door cabinets, but not necessarily at same time) by a rope located not more than three inches back from the latch side of the top-edge of the door. To preclude tilting or upsetting during the test, counterweights may be placed within the cabinet. In a normal manner the door shall be pivoted back and forth, at least 110 degrees in each direction: Each door shall be pivoted each way not less than six times. The weight shall then be removed from the door. If the door binds when closed or fails in any other respect it shall be considered as having failed the test. Failure to pass the test shall be cause for rejection.
Shelf load test. This test shall be performed on shelves in Type 1, class 1 cabinets only. The required number of shelves for the cabinet being tested shall be adjusted so that they are as equidistant as possible from each other and from the top and bottom of the cabinets. The tests shall be performed consecutively on each shelf. The test area shall be the entire top of the shelf minus three inches from each side. A weight of 60 pounds shall be equally distributed on the area specified. The weight shall remain on the-shelf at least 15 minutes. With the weight on the shelf, a measurement shall be taken from the bottom center of the shelf downward to a point of reference established before the weight was applied. The shelf shall not have more than 1/4 inch deflection while loaded or 1/6 inch permanent deflection after the load is removed. The cabinet shall then be visually examined. Any damage to the shelf support, deformation of any component, cracked or broken welds, or loosening of any fastening device shall be cause for rejection.
