deformation of the snap link shall constitute failure of this test. Deformation shall be determined by operating the gate, if the gate functions properly there is no deformation of the snap link. Snap links with the gate closed and the locking nut in the closed position shall be tested in accordance with the same procedure except that the final load shall be
3600 kg. The snap links shall withstand the 3600 kg load without breaking of cracking.
Snap links subjected to this test shall be discarded. Snap links shall be tested for
operation of the locking nut and gate by screwing the nut from the open position to the locked position and then back to the open position. The gate shall then be moved from the closed position to the completely open position and then released. Any jamming of the nut or gate shall be considered a failure. Any test failure shall be cause for rejection of the lot.
3.4.3 Type III. The type III nonlocking snap link shall be capable of withstanding an
1800 kg proof test load in the longitudinal direction and the gate in the closed position without the snap link breaking or cracking.
3.4.3.1 Proof load test, Type III. Any desired operating speed may be used until a load of 1170 kg is reached. After reaching that point the speed shall be maintained at not more than 4 inches per minute or less than 1 inch per minute until a load of 1800 kg is reached. This load shall be maintained for not less than 10 nor more than 15 seconds.
The snap links shall withstand the 1800 kg load without breaking of cracking. Snap links
subjected to this test shall be discarded. Snap links shall be tested for operation of the gate by moving the gate from the closed position to the completely open position and then released. Any jamming of the nut or gate shall be considered a failure. Any test failure shall be cause for rejection of the lot.
3.5 Identification marking. All snap links shall be stamped with the manufacturer's identification symbol, and its maximum rated test strength.
