Type A, Type B, and Type C car safeties, except those operating on wood guide rails, and their governors
, wire rope gripping safeties with slack-rope actuation, or wire rope gripping safeties with an internal centrifugal governor

at the rated speed
. The overspeed switch on the governor
shall be made ineffective during the test. Type A safeties and wire rope gripping safeties without governors
that are operated as a result of the breaking or slackening of the hoisting ropes shall be tested by obtaining the necessary slack rope to cause it to function (Item 126.96.36.199) and hold the car with rated load. The following operational conditions shall be checked (Item 188.8.131.52).
