18.104.22.168 Periodic Test Requirements — Category 5
NOTE: For test frequency, see 22.214.171.124.
(a) Rated Load and Rated Speed Test. Car safeties, except those operating on wood guide rails, and their governors, shall be tested with rated load in the car. Counterweight safety tests shall be made with no load in the car. The car speed at which the governor trips shall be determined by means of a handheld tachometer or other device designed to measure car speed, such as controllers, service tools, and accelerometers. Tests shall be made by tripping the governor by hand at the rated speed. If the governor is equipped with a switch that operates when the governor is manually tripped, it must be rendered inoperative. The car safety mechanism switch shall not be rendered inoperative. The emergency brake required by 2.19.3 shall be disabled to prevent it from operating during this test. Since the counterweight safety does not have a safety mechanism switch, the circuit that would remove power from the driving-machine motor and brake must be opened as soon as the elevator stops to minimize slack rope and fallback of the car. The following operational conditions shall be checked (Item 2.29.2):
(1) Type B safeties shall stop the car with the rated load within the required range of stopping distances for which the governor is tripped (Item 2.29.2) and the level of the platform checked for conformance with 126.96.36.199.
(2) For Type A safeties and Type A safety parts of Type C safeties, there shall be sufficient travel of the safety rollers or dogs remaining after the test to bring the car and its rated load to rest on safety application at governor tripping speed. The level of the platform shall be checked for conformance with 188.8.131.52.
(b) Alternative Test Method for Car Safeties. The alternative test methods shall comply with 184.108.40.206 and the following:
(1) The testing of safeties with any load in the car, centered on each quarter of the platform symmetrically with relation to the centerlines of the platform from no load up to rated load, and at not less than rated speed shall be permitted provided that both
(-a) when the alternative test is performed, the test shall stop the car and verify that the safeties will be capable of stopping an overspeeding car in accordance with the requirements of Section 2.17 applicable to the specific classification of safeties
(-b) when applied, the method shall verify that the safeties perform or are capable of performing in compliance with (a) and the platform shall not be out of level more than 30 mm/m (0.36 in./ft) in any direction
(2) The "Periodic Test Record" shall be completed and installed as required in 220.127.116.11.2
(a) The tripping speed of the governor and the speed at which the governor overspeed switch, where provided, operates shall be tested to determine conformance with the applicable requirements, and the adjustable means shall be sealed (Item 18.104.22.168).
(b) The governor rope pull-through and pull-out forces shall be tested to determine conformance with the applicable requirements, and the adjustment means shall be sealed (Item 22.214.171.124).
(c) After these tests in jurisdictions enforcing the NBCC, a metal tag indicating the date of the governor tests, together with the name of the person or firm that performed the tests, shall be attached to the governor in a permanent manner.
(a) Car oil buffers shall be tested to determine conformance with the applicable requirements by either
(2) subject to approval by the authority having jurisdiction, either
(-a) running the car with any load, from no load up to rated load onto the buffer at rated speed when the requirements of 126.96.36.199 are complied with, provided that when applied the method verifies that the buffer performs or is capable of performing in compliance with (a), except as specified in (b) and (c) (Item 188.8.131.52). Counterweight oil buffers shall be tested by running the counterweight onto its buffer at rated speed with no load in the car, except as specified in (b) and (c) (Item 184.108.40.206)
(-b) running the car onto the buffer with any load, from no load up to rated load, and at less than rated speed, when the requirements of 220.127.116.11 are complied with, provided that when applied, the method verifies that the buffer performs or is capable of performing in compliance with (a)
(b) For reduced-stroke buffers, this test shall be made at the reduced striking speed permitted (Item 18.104.22.168).
(c) This test is not required where a Type C safety is used (see 22.214.171.124.1).
(d) In making these tests, the normal and emergency terminal stopping devices shall be made temporarily inoperative. The final terminal stopping devices shall remain operative and be temporarily relocated, if necessary, to permit compression of the buffer during the test.
(f) Counterweight oil buffers shall be tested by running the counterweight onto its buffer at rated speed with no load in the car, except as specified in (b) and (c) (Item 126.96.36.199), or at reduced speed if the requirements of 188.8.131.52 are met.
For elevators installed under ASME A17.1-2000/CSA B44-00 and later editions, have the brake setting verified in accordance with the data on the brake marking plate.
Upon completion of the test, the means of adjusting the holding capacity shall be sealed to prevent changing the adjustment without breaking the seal. The seal shall bear or otherwise attach the identification of the person or firm that installed it. (See also 184.108.40.206.2, Periodic Test Record.)
(a) Test with load per Table 220.127.116.11.4. Place the load as shown in Table 18.104.22.168.4 in the car. The driving-machine brake, on its own, shall hold the car with this load. With no load in the car, the driving-machine brake shall hold the empty car at rest, and shall decelerate an empty car traveling in the up direction from governor tripping speed. The driving-machine brake on freight elevators of Class C2 loading, when loaded to their maximum design load, shall hold the elevator car at rest (Item 22.214.171.124).
(1) Any method of verifying conformity of the driving-machine brake with the applicable Code requirements (see 126.96.36.199 and Table 188.8.131.52.4) shall be permitted, including the testing method of the brakes with or without any load in the car, provided that when applied, the method verifies that the brake performs or is capable of performing in compliance with (a).
Table 184.108.40.206.4 Brake Test Loads

(a) Dynamic Stopping Test. Traction elevators shall be tested to ensure that
(1) during an emergency stop initiated by any of the electrical protective device(s) listed in 2.26.2 (except 220.127.116.11) (except buffer switches for oil buffers used with Type C car safeties) at the rated speed in the down direction, with passenger elevators and freight elevators permitted to carry passengers carrying 125% of their rated load, or with freight elevators carrying their rated load, cars shall safely stop and hold the load (see 18.104.22.168.1 through 22.214.171.124.3)
(-a) the suspension means shall lose traction with respect to the drive sheave and not allow the car or counterweight to be raised
(-b) the driving system shall stall and not allow the car or counterweight to be raised
(3) With a load in the car in accordance with Table 126.96.36.199.4, the braking system and traction relation shall be tested to show that the system can safely stop and hold the car and, where required by 188.8.131.52.4(c), shall relevel the car.
(-a) When applied, the method shall verify that the elevator traction system performs, or is capable of performing, in compliance with the performance requirements of (a).
(-b) The braking system and traction relation shall be tested to show the system can safely stop and hold the car and, where required by 184.108.40.206.4(c), shall relevel the car without a load in the car.
(a) Emergency Brake and Ascending Car Overspeed Protection. For passenger elevators and all freight elevators, the emergency brake shall be tested for compliance with 220.127.116.11. Verify the setting of the ascending car overspeed detection means.
(b) Emergency Brake and Unintended Car Movement Protection. Test the unintended car movement protection and the emergency brake in the down direction with 125% of rated load at the landing above the bottom landing.
