3.2.2
Field Tests
3.2.2.1
Endurance Tests
Test each elevator for a period of one hour continuous run, with specified
rated load in car. Restart the one hour test period from beginning,
following any shutdown or failure. During test run, stop car at each floor
in both directions of travel for standing period of 10 seconds per floor.
The requirements for Rated Speed, Leveling, Temperature Rise and Motor
Amperes Test specified herein are to be met throughout the duration of the
Endurance Test.
3.2.2.2
Speed Tests
Determine actual speed of each elevator in both directions of travel with
rated load and with no load in elevator car. Make Speed tests before and
immediately after Endurance test. Determine speed by tachometer reading,
excluding accelerating and slow-down zones per ASME A17.2.1. Minimum
acceptable elevator speed is the Rated speed specified. Maximum acceptable
elevator speed is 110 percent of Rated speed.
3.2.2.3
Leveling Tests
Test elevator car leveling devices for landing accuracy of plus or minus 6
mm 1/4 inch at each floor with no load in car, symmetrical load in car, and
with rated load in car in both directions of travel. Determine accuracy of
floor landing both before and immediately after endurance tests.[ For
Class C2 landing, freight elevators shall comply with ASME A17.1, Rules
207.2b (3)(a), (b) and (c). The maximum load on car platform during
loading or unloading shall not exceed 150 percent of rated load.]
3.2.2.4
Perform tests to ensure elevator wiring systems are free from short
circuits and grounds. Minimum acceptable insulation resistance for
electrical conductors is one megohm between each conductor and ground and
between each conductor and other conductors. Prior to megohm meter test,
make provisions to prevent damage to electronic devices.
3.2.2.5
Brake Test
Conduct brake test with 125 percent of rated load in elevator.
Verify that
brakes stop and hold elevator with 125 percent of rated load.
3.2.2.6
Buffer Tests
Test buffers for car and counterweight as outlined in ASME A17.1, Rule
1100.5.
3.2.2.7
Temperature Rise Tests
Determine temperature rise of elevator hoisting motor, motor-generator,
exciter, and booster during full-load test run for one hour minimum. Under
these conditions, maximum acceptable temperature rise shall not exceed
acceptable temperature rise indicated on manufacturer's data plate. Start
test only when equipment is within 5 degrees C of ambient temperature.
