Temperature-pressure: 0,000001atm and temperature raised to 71º C. Temperature then lowered to -18º C in 45 minutes and again raised to 71º C in 45 minutes. This cycle was repeated fifteen times.
Relative humidity: 240 hours in relatuve humidity of at least 95% and at temperatures varying between 20º C and 71º C. The steam had a pH value of between 6,5 and 7,5.
Oxygen atmosphere: Exposure to 100% oxygen atmosphere at a pressure of 0,35atm and a temperature of 71º C for 48 hours.
Shock: Six 11 millisecond shocks of 40g each in six different directions.
Acceleration: Linear acceleration from 1g to 7,25g within 333 seconds.
Decompression: 90 minutes in a vaccum of 0 10-6 atm and a temperature of 71º C and 30 minutes in the same vaccum but at a temperature of 93ºC.
High pressure: Exposure to 1,6atm for one hour.
Vibration: Three cycles of 30 minutes (lateral, horizontal and vertical), the frequency varying from 5 to 2000cps and back to 5cps in 15 minutes. Average acceleration per impulse 8,8g.
Acoustic noise: 130dB over a frequency range from 40 to 10000Hz for 30 minutes
