31、spection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in the specification where such inspections are deemed necessary to assure supplies and services conform to prescribed requirements. 4.2.1 Disas
32、sembly inspection. Failure of any examination or test by the preproduction model shall be cause for disassembly, in the presence of a Government representative, of the preproduction model to the extent necessary to determine the cause of the failure. Each disassembled part shall be examined in detai
33、l for compliance with this specification and referenced drawings in regard to materials, dimensions, tolerances, and workmanship. Parts not complying with such requirements shall be rejected. 4.2.2 Component and material inspection. The contactor is responsible for insuring that components and mater
34、ials used are manufactured, examined, and tested in accordance with referenced specifications and standards. 4.3 First article inspection. 4.3.1 Examination. The first article control-panel assembly shall be examined as specified in 4.5.1. Presence of one or more defects shall be cause for rejection
35、 and for performing the disassembly inspection specified in 4.2.1. 4.3.2 Tests. First article inspection shall subject one control-panel assembly to the examination and tests specified in 4.5.2. The manufacturer shall provide verification to the procuring activity that the first article inspection a
36、nd tests have been performed on the control-panel assembly supplied to the requirements of this specification. One or more failures of first article tests shall be cause for rejection and for performing the disassembly inspection specified in 4.2.1. 4.4 Conformance inspection. 4.4.1 Examination. Eac

41、sembly from a 115 volt, AC, 60 HZ power source. Set the autotransformer control dials on 100 volts. Connect two 100 watt, 110/115 volt lamps parallel to any one of the three circuits controlled by autotransformers. Actuate the master switch to the “ON” position. Set the appropriate autotransformer c
42、ontrol dial to the maximum voltage position and operate for 10 minutes. Measure the output voltage. Reset the control dial to 100 volts. Repeat this test by alternately applying the lamp load to the other three output circuits. An output voltage of more than 120 volts, or less than 112 volts, or mal
43、function of the switch, shall constitute failure of this test. 4.5.2.2. Temperature and humidity.

Cold soak the control-panel assembly at
44、 -50F for a period of 12 hours. Test the control-panel assembly at maximum voltage for a period of 1 hour with one 100 watt lamp in each of the four circuits. At the end of each 15 minute period, adjust the autotransformers from maximum to minimum position and open and close the circuit breaker. Ina
45、bility of the control-panel assembly to operate, or malfunction of any component, shall constitute failure of this test. 4.5.2.2.2 High temperature and humidity storage and operation. Place the control-panel assembly in a test chamber with 80 to 98 percent relative humidity at an ambient temperature
46、 of +155F for 24 hours; reduce the temperature to +120F for 24 hours prior to start of operational tests. Check the circuit breaker by adjusting the output load to 15 percent overload (5.75amperes) for 1 hour. Increase the output load to 25 percent overload (6.25 amperes) and determine the time requ
47、ired to trip the circuit open. Nonconformance to 3.4, damage to the breaker or other components during overload, or nonconformance to 3.6 shall constitute failure of this test.
