Current through Register Vol. 54, No. 28, July 13, 2024
(a) New passengers
					 and freight elevators shall be tested in the presence of a Department inspector
					 to see that the car safeties, speed governors, brakes, bumpers, limit switches,
					 and the like, perform their proper functions. The car safeties shall be tested
					 with the elevator car carrying the maximum allowable load. In making the final
					 test the hoisting cables shall be detached from the car, while at a height
					 sufficient to indicate the efficiency of the car safeties. A runaway test is
					 acceptable in lieu of the free drop test when approved safety devices are
					 installed. For reostatic control elevators, the safeties shall be tested by
					 tripping the governor. Broken rope safety devices shall be tested as
					 such.
(b) Existing installations
					 shall be tested as follows:
(1) The car safety
					 of existing installations shall be tested with rated load in the car by
					 tripping the governor by hand at rated speed, within five years of effective
					 date and at least every five years thereafter by a reputable elevator company.
					 Results of the test shall be certified by the elevator company on forms
					 furnished by the Department, indicating the load for which the elevator was
					 tested and a record of such test shall be filed with the Department.
(2) A metal data plate furnished by the
					 company performing the test shall be fastened to the car crosshead and show the
					 date of the test and the company performing the test.
(3) The governor shall be tested and the trip
					 speed measured by a tachometer and, if necessary, adjusted to conform to the
					 requirements of this section. Governors shall be resealed after each test.
					 Speed governors for car safeties shall be set to trip at over speeds as
					 follows:
(i) At not less than 115% of rated
					 car speed.
(ii) At not more than
					 the tripping speed listed opposite the applicable rated speed in the following
					 table:
Maximum Speeds at which Speed Governor Trips and
						Governor Overspeed Switch Operates
Rated Speed (in feet per
								  minute)
Maximum Governor Trip Speed (in feet per
								  minute)
Maximum Speed at which Governor Overspeed
								  Switch Operates (down feet per minute)

(4) Speed governors, where provided for
					 counterweight safeties, shall be set to trip at an overspeed greater than, but
					 not more than 10% above, that at which the car speed governor is set to
					 trip.
(5) Broken rope safeties
					 shall be drop tested.
(6) The
					 provisions of this subsection do not apply to hand-powered freight
					 elevators.
