The Internet Archive:

Twelve firings of the Rocketdyne J-2 rocket engine (S/N 2047) were conducted in Test Cell J-4 of the Large Rocket Facility on March 27 and April 2 and 10, 1968. These firings were accomplished during test periods J4-1801-34, J4-1801-35, and J4-1801-36 at pressure altitudes of approximately 100,000 ft at engine start to investigate S-IVB (1) first burn firings, (2) 6-hr orbital coast restart simulation firings, (3) 80-min orbital coast restart simulation firings, and (4) a partial transition firing to evaluate thrust chamber conditioning temperature effects on engine start transients. Engine operation was satisfactorily accomplished for all firings. One abort resulted when a leak developed in the diaphragm of the engine pneumatic regulator. The accumulated firing duration for the three test periods was 205 sec. The total firing duration of this engine at AEDC through test period J4-1801-36 is 1141 sec resulting from 91 engine firings.
