For the static leakage test, what are the starting conditions?

• A.Engine idling fast with brakes applied hard
• B.Tanks half full with the parking brake set
• C.Engine off with the tanks drained to 60 psi
• D.Engine off, reservoirs fully charged to governor cut-out, and brakes released

Why

Leakage limits only mean something from a known starting point: full tanks, engine off so the compressor cannot hide a leak. The driver then watches the gauges for a timed minute with no brake application.
