Slides for wood and furniture applications are tested in accordance with the guidelines of applicable ANSI/BIFMA specifications. Certain models have been BHMA certified or WI approved. In most cases, hardware alone cannot be rated; the testing standards pertain to the end product. Our goal is to provide products that, when combined with the purchaser's product, deliver a system that meets the governing standard.
Unless otherwise stated, Accuride slides are rated for the dynamic (cycled) load that an 18" pair of slides will carry without failure. This load rating decreases proportionally beyond the 18" length.
In the dynamic test, the center of gravity of the load is balanced between and at the midpoint of the drawer members.
Static (resting) load testing is based on placing 2 times the maximum permissible load in a fully extended drawer for 24 hours. The slides are measured for deflection at 0 hours and again at 24 hours.
In all cases, the static load capacity of each model is at least twice the dynamic load rating, providing at minimum, a 100% static safety factor, even when the slide is loaded to its maximum rating.
Standard test criteria for box, file, and desk drawers (drawers narrower than deep):
50,000 dynamic cycle tests.
Standard test criteria for lateral file drawers (drawers wider than deep):
A total of 75,000 dynamic cycle tests: 55,000 cycles from the center of the drawer and 10,000 cycles from each side.
Industrial & Electromechanical Product Testing Standard Test Criteria/Basis of Load Rating
The maximum load rating is based on a pair of side-mounted slides.
The center of gravity of the load is centered between and at the midpoint of the drawer/chassis members.
Unless otherwise stated, testing is based on 18" slides mounted on a 16" wide drawer. This load rating decreases proportionally beyond the 18" length.
Dynamic tests are based on 10,000-cycles and include a 100% static safety factor.
Static (resting) load testing is based on placing 2 times the maximum permissible load in a fully extended drawer for 24 hours. The slides are measured for deflection at 0 hours and again at 24 hours.
