CABINET LOAD TEST
DOOR HINGE TEST
4.2.1 Purpose of Test The cabinet load test challenges the structural integrity and the load-bearing capability of the cabinet construction. The test demonstrates the ability of the cabinet to support heavy loads. 4.2.2 Test Procedure The cabinet top was loaded using 2,000 pounds of solid steel bars stacked five high, in eight equally spaced rows. After 10 minutes, the bars were removed from the cabinet. 4.2.3 Acceptance Level There are no signs of permanent damage.
5.1.1 Purpose of Test The test demonstrates the durability of the door and its hardware to an applied load of 200 pounds. 5.1.2 Test Procedure The shelf was removed and weight was placed on top of the cabinet to prevent it from overturning. A cabinet door was opened 90˚ and a sling with four 50 pound weights was hung over the top of the door, at a point out from the hinge centerline. The door was then slowly moved through the full cycle of the hinge (up to a 160˚ arc). The weight was then removed, the door was swung through its full intended range of motion, and closed. 5.1.3 Acceptance Level There was no significant permanent distortion and the door operated normally after the weight was removed.
CABINET CONCENTRATED LOAD TEST
4.3.1 Purpose of Test The purpose of the test is to challenge the functional characteristics of the cabinet when subjected to a concentrated load on the center of the cabinet top. 4.3.2 Test Procedure Four, 50 pound solid steel bars were placed on top of the cabinet, along the cabinet centerline. With the weight in place, the drawers and doors were operated and inspected. 4.3.3 Acceptance Level Doors and drawers operated normally. There is no permanent distortion to the front rail, cabinet joinery, doors, or drawers. 4.4.1 Purpose of Test The test evaluates the structural integrity of the cabinet construction when subjected to torsional load. 4.4.2 Test Procedure The cabinet was supported on three, 3-1/4” x 3-1/2” x 4”H hardwood blocks, located under the two rear corners and one front corner. The cabinet was secured, diagonally from the unsupported corner with seven, 50 pound, solid steel bars to prevent overturning. Four, 50 pound, solid steel bares were placed on the unsupported corner of the cabinet and left in position for 15 minutes. The weights were then removed and the cabinet was placed on the floor in its normal, upright, position. The cabinet joinery was inspected and the cabinet was leveled and measured, diagonally, between the corners of the face and the back of the cabinet. 4.4.3 Acceptance Level When returned to normal position, the operation of the cabinet was normal and there was no evidence of permanent damage. The difference between the diagonal measurements does not exceed 1/8” front or back. CABINET TORSION 4.5.1 Purpose of Test The test demonstrated the ability of a cabinet to resist standing water. 4.5.2 Test Procedure The thickness of the material along the perimeter of the bottom of the cabinet was measured on 6” increments. The thickness was recorded and the arithmetic mean was calculated. The cabinet was then placed in a pan of water so that the bottom 2” of the cabinet was submerged. The cabinet remained in the water for 4 hours and then it was removed and immediately re-measured at the same locations that were measured ini- tially. The thickness at each location was recorded and the arithmetic mean was calculated. After the cabinet had dried, it was inspected for damage. 4.5.3 Acceptance Level The cabinet shows no signs of permanent deformation or deterioration and the average increase in thickness is less than four percent (3.5%). CABINET SUBMERSION TEST
DOOR IMPACT TEST
5.2.1 Purpose of Test The test demonstrates the resistance to a 240 inch-pound impact to the door face. 5.2.2 Test Procedure Eight, 50 pound solid steel bars were placed on top of the cabinet to prevent overturn- ing. A 20 pound sand bag was then suspended from a pendulum support and dropped providing an impact of 240 inch-pound at the center of a closed door. 5.2.3 Acceptance Level Door and catch operated normally and show no signs of permanent damage.
DOOR CYCLE TEST
5.3.1 Purpose of Test The test demonstrates the ability of the door hinge hardware to withstand 100,000 cycles as a reliable measure of longevity. 5.3.2 Test Procedure A cycling mechanism, that swings a door through an arc of 90˚, was operated for 100,000 cycles. 5.3.3 Acceptance Level The door operated for the full 100,000 cycles without deterioration that significantly affected the function of the door. After completion of the test, the door operates freely and without binding. 6.1.1 Purpose of Test The test demonstrates the ability to support a point load given to the front of the drawer and will challenge the attachment of the drawer head to the drawer. 6.1.2 Test Procedure Eight, 50 pound solid steel bars were placed on to of the cabinet to prevent overturning. A drawer was opened to 13” of travel and 150 pounds was hung from the drawer head, at the centerline of the drawer, for 5 minutes. The weight was then removed and the drawer was operated through the full cycle. 6.1.3 Acceptance Level There was no interference with the normal operation of the drawer. DRAWER STATIC LOAD TEST
