DRAWER & DOOR PULL TEST
6.2.1 Purpose of Test The test evaluates the strength of the pull and the pull hardware. 6.2.2 Test Procedure
The pulls were installed in accordance with Diversified Woodcrafts practice using spec- ified attaching hardware and method. A drawer and a door were blocked closed and a cable, pulley, and weight assembly was used to apply a force of 50 pounds perpendicular to each pull. Similar set-up was then used to hang a 50 pound weight from each pull. 6.2.3 Acceptance Level Pulls resisted the force and supported the weight and there is no evidence of permanent distortion.
DRAWER IMPACT TEST
6.3.1 Purpose of Test The test demonstrates the resistance to impact of the drawer bottom and the slide mecha- nism. 6.3.2 Test Procedure A drawer was opened to 13" of travel and then a 10 pound sand bag was dropped, from a height of 24", into the bottom of the drawer, at the centerline of the width of the drawer and 6" back from the inside face of the drawer. 6.3.3 Acceptance Level The drawer was operated through a full cycle and it operated normally. There was no visible deformation of the drawer. 6.4.1 Purpose of Test The test evaluates the strength of the drawer head, bottom, and back as a result of opening and closing the drawer with a rolling load. 6.4.2 Test Procedure The drawer was positioned on a table at a 45˚ angle and a 2" diameter by 12" long steel rod, that weighs approximately 10 pounds, was positioned 13" from the target impact area such that the rod rolled freely to impact the back of the drawer. The back was subjected to three impacts and then the drawer was reversed and the front was subject to three additional impacts. 6.4.3 Acceptance Level There are no visible signs of permanent damage. All joinery is intact and the drawer operat- ed normally when returned to the unit. DRAWER INTERNAL ROLLING IMPACT 6.5.1 Purpose of Test The test is intended to replicate years of operation of a drawer under full load. 6.5.2 Test Procedure A static load of 100 pounds (using ten 10 pound sand bags) was uniformly distributed in a drawer and the force required to activate the drawer was measured. The drawer was then opened from a closed position to a position within 1/4" of full extension and then closed. The procedure was repeated 50,000 times at a rate that did not exceed 10 cycles per minute. 6.5.3 Acceptance Level After the 50,000 cycles were completed, the drawer operated freely with no evidence of dragging, rubbing, or binding. The force required to open and close the loaded drawer increased by 7.1% which is less than the allowable maximum (20%). The force required to open and close the loaded drawer was less than 8 pounds.
