NOTES:
1/
Test applies for individual contactors and associated switching devices.
2/
Test applies for solid-state associated switching devices.
3/
Test applies for controllers which are assembled with components qualified to this specification. Completely
assembled nonreversing, dripproof motor controller of each size for only the following basic types:
Across-the-line (single- and two-speed); reduced voltage (autotransformer, primary resistor, primary reactor,
wye-delta, and resistor).
4/
Test applies only to time delay relays.
5/
Test applies for pressure and temperature switches.
6/
When required (see 6.2).
7/
Test applies to qualification of devices operated under the condition of voltage ramp.
4.3.3 Samples for qualifications. One to five samples of each type contactor, controller, or associated
switching device, for which qualification is desired shall be submitted for qualification testing.
4.3.4 Order of tests. Unless otherwise specified (see 6.2), the tests for general operation, effectiveness of
enclosure, insulation resistance, dielectric, pickup and dropout, terminal strength, voltage variation, overload
protection, and voltage ramp shall precede and follow shock and vibration tests. The endurance test shall precede
the shock test.
4.3.5 Disposition of qualification units. Samples subjected to qualification inspection shall be considered
consumed and nondeliverable as specified (see 6.2).
4.3.6 Failures. Failure of any sample to meet the requirements specified herein shall be cause for disapproval
of or removal of product qualification.
4.4 Conformance inspection. Conformance inspection shall be as specified in table XIII. The routine
inspections specified in table XIII shall be performed on each equipment furnished (100 percent inspection)
including each component of a motor controller that consists of several parts.
