AA-F-358J
4.6.1 Drawer pull test. The drawer shall be loaded with the applicable
weight specified in 4.6. The force required to move the drawer outward (not
less than one inch from its fully closed position) to its fully open position,
and the force to move the drawer inward from the fully open position to the
point where it contacts the latch or lock mechanism shall not exceed 10 pounds.
4.6.2 Out stop test. The drawers shall be loaded as specified in 4.6. A limp cable shall be attached to the center of the pull or handle and extended horizontally to and over a pulley. The opposite end of the cable shall extend downward, and a weight equal to 20% of the drawer load shall be attached to
the free end. The drawer shall be released, permitting the weight to land on a platform when the drawer is within 6 inches of full extension. The drawer movement shall continue, without application of further force, until the
drawer contacts the out stops. The test shall be repeated three times. Any deformation of the stop shall be considered a failure.
4.6.3 Rack test. The cabinet with all drawers loaded as specified in 4.6 shall be raised not less than one inch to a position of being supported at two diagonally opposite corners. The area of support shall be not greater than 6 inches from each corner. Two hundred fifty pounds of weight shall be still loaded on the cabinet top at each of the two unsupported corners. The cabinet shall remain in this position for not less than 24 hours. The cabinet shall
then be returned to its normal upright level position and examined as specified in 4.6. Failure of any moving part, including the drawer test in 4.6.1, or any resulting damage to the security protection afforded by the cabinet, shall be considered as failure to meet the test requirements.
4.6.4 Service test. Prior to the test the cabinet shall be loaded as specified in 4.6. The drawer selected for the test shall be connected by its drawer pull to a test machine which shall operate the drawer in and out on the drawer suspension. The machine shall have a positive means (no springs) for adjusting its stroke so that the drawer will travel its full distance (1/4 inch clearance is permitted at the end of each stroke). The machine shall in no way contribute to the support of the drawer. The machine shall drive the drawer at
a rate of 20 cycles per minute, +2 cycles for 50,000 cycles. The drawer suspension shall be cleaned and lubricated with a lubricant recommended by the manufacturer at the end of 10,000 cycles and shall have no further servicing during the test. The drawer shall be examined and subjected to the pull test in
4.6.1 and the out stop test in 4.6.2 at the beginning of the test and at each increment of 10,000 cycles. The drawer suspension shall have failed the test if the drawer operating force exceeds ten pounds at any time during the test.
4.6.5 Moving test. The cabinet with all drawers loaded with typical
filing material of the applicable weight specified in 4.6 and with the follower
block drawn up tight against the filing material, shall be tipped backwards to
a 45 degree angle. The cabinet shall remain in this tilted position for not
less than three hours. At the end of this time it shall be returned to its
normal upright position and examined in compliance with 4.6. There shall be no
damage to the cabinet or its component or displacement of the drawer's contents
as a result of the test. Failure of the test shall provide reason to reject the
sample.
4.6.6 Follower block test. A drawer of the cabinet shall be loaded with
40 pounds of typical filing material which shall be held against the front of
the drawer by the follower block. The location of the follower block shall be
indicated by a mark placed on the bottom of the drawer. The machine specified
in 4.6.3 for operating the drawer shall be connected to the drawer and set in
motion and made to operate for 500 cycles. Upon completion of 500 cycles of
operation, the position of the follower block shall again be indicated by a
mark on the bottom of the drawer. Any rearward movement of the follower block,
as indicated by the distance between the two marks, shall not exceed 1/2 inch.
The follower block shall be examined for compliance with 3.3.5.1 or 3.3.5.2, as
applicable.
