APTA “Recommended Instrumentation and Performance Testing for Transit Bus Air Conditioning System,” representing 4 P.M. on August 21, shall be used. There shall be no passengers on board, and the doors and windows shall be closed.

The pull up requirements for the heating system shall be in accordance with Section 9 of APTA’s “Recommended Instrumentation and Performance Testing for Transit Bus Air Conditioning.” With an ambient temperature of -15° F, and the bus cold soaked at that temperature, the bus heating system shall warm the center passenger compartment to an average temperature of 70°±2ºF within 70 minutes.

Testing shall be conducted in accordance to the APTA Recommended Instrumentation and Performance Testing for Transit Bus Air Conditioning System. Temperature measurements shall be made in accordance to this document with the following modifications:

The three primary locations used for temperature probes are (1) 6 inches aft of front wheel housing, (2) centered between the two axles and (3) 6 inches aft of rear wheel housing. At each primary location, the nine (9) temperature sensing devices shall be (A) 72 inches above floor level, (B) 6 inches above top surface of seat cushion and (C) 6 inches above floor.

The recommended locations of temperature probes are only guidelines and may require slight modifications to address actual bus design. Care must be taken to avoid placement of sensing devices in immediate path of air duct outlet. In general, the locations are intended to accurately represent the interior passenger area.

Battery terminals shall be located for access in less than 30 seconds with jumper cables. Battery cables shall be flexible and sufficiently long to reach the batteries in the extended tray position without stretching or pulling on any connection. Cables shall not lie on top of batteries. The battery terminals and cables shall be color-coded with red for the primary positive and black for negative.

The battery tray shall be made of stainless steel, or polyethylene, and shall pull out easily and properly support the batteries during service, filling by manual or automatic equipment, inspection of water levels, and replacement. In the normal position, the battery tray shall not be supported by rollers. A positive lock shall retain the battery tray in the normal position. Batteries shall be easily accessible for inspection, serviceable only from outside the bus, securely mounted on a sliding or swing out stainless steel rollers, treated to prevent corrosion and be readily accessible for servicing, under the bus floor and separate from the engine compartment.
