MIL-T-62223B(AT)

refrigerators, lights and at least one auxiliary electric heater shall be operated. The lights and electrical equipment shall be observed to verify that the auxiliary generator provides sufficient electrical power for satisfactory operation during transit (see 3.5.6.4). Upon completion of the road test, the vehicle, components and accessories shall be examined for damage and leakage (lubricant or air). All equipment permanently installed or secured for transit shall be examined for damage.

4.4.3 Radio frequency suppression verification. The vehicle manufacturer shall indicate on the military questionnaire (commercial vehicle engineering data), if the vehicle will be suppressed to limit electromagnetic radiation in accordance with SAE J551.

4.4.4 Functional tests. After completion of the final road test the following functional tests shall be performed.

4.4.4.1 Electrical system test. To determine conformance to 3.5.6 through 3.5.6.2, the electrical system shall be subjected to a functional test. The satisfactory performance of the electrical system shall be verified, with the air conditioner operating, and then all lighting shall be turned on. The lighting shall be observed during the phase-in operation of the air

conditioning compressor, to verify that the lighting does not fade. The air conditioning unit shall

be observed for satisfactory operation. The power and electric circuits shall be verified to assure that the power load is in accordance with the specified requirements and actual loads imposed.

4.4.4.2 Air conditioning test. To determine conformance to 3.5.7, the air conditioning system shall be subjected to a functional test. The air conditioning vehicle body combination shall be tested under actual or simulated conditions at least as stringent as the specified requirements. Simulated conditions acceptable to the Government may be used. Performance of the air conditioning system shall be verified to determine that the system is capable of maintaining the inside of the vehicle body at an evenly circulated cooling temperature of 72°F (22°C) maximum in a 95°F (35°C) outside ambient. Inside temperature may be calculated either with the number of occupants required or through the use of a simulated heat load for sensible cooling.

4.4.4.3 Heating test. To determine conformance to 3.5.8, the vehicle body heating system shall be subjected to a functional test. The electric fan blower heaters and vehicle body shall be tested under actual or simulated conditions at least as stringent as the specified requirements. Simulated conditions must be acceptable to the, Government. Performance of the heating system
