KCMA Drawer Closing Impact

ANSI-KCMA General Test Requirements


All tests shall be made on cabinets installed according to manufacturer’s instructions except where otherwise specificed.

All tests shall be run at room temperatures of 20 to 27 degree Celsius(68 to 80 degree Fahrenheit) and at a relative humidity of 35 per cent to 70 per cent unless otherwise specified.

Drawer Closing Impact

Purpose: To test ability of the drawer-front assembly to withstand the drawer closing impact normally expected in household usage.

Test Procedures:
A. Mount drawer in test stand as shown in drawing. Do not use drawer used in test.

B. Attach clamps to drawer sides 25mm (1 inch) above drawer back.

C. Adjust loading bars to the full width of the inside of the drawer. Lay bars on top of clamps. Loading Bar: Testing apparatus comprised of 3 component parts;2 Drawer-closing Impactsteel bars and 1 bolt. Dimensions – Top bar;length 102mm(4 inches), width 76mm (3 inches), thickness 12.7mm (1/2 inch) with a 12.7mm by 12.7mm (1/2 inch by 1/2 inch) by 76mm (3 inches) shim welded under one end. Bottom bar; length 229mm (9 inches), width 76mm (3 inches), thickness 12.7mm (1/2 inch). Total approximate weight 2.72kg (6 pounds). During the testing process the bottom bar is placed under the top bar so the bottom bar and the shim on the top bar are in the same horizontal plane. The bars are joined by a machine bolt passing through the top bar threaded into the bottom bar. This enables the top bar to be adjusted to the width of the drawer.

D. Drop 1.36 kg (3 pound) steel ball 203mm (8 inches) onto the center of the loading bars. Repeat for a total of 10 drops.

Required Performance: No looseness or structural damage to the drawer-front assembly that impairs operation of the drawer shall be allowed.
