Borra- doporučuji si přečíst něco o testech, kterými Moony musely projit, pak se tekoucí vody z umyvadla nebudeš bát... 11 Types of Tests NASA designed a couple of tests for these watches, that weren?t meant to keep the watches in one part. These tests were designed to test the watches to destruction. In a relatively short period (of months), the following tests were performed on the watches: 1. High temperature 48 hours at a temperature of 160°F (71°C) followed by 30 minutes at 200°F (93°C). This under a pressure of 5.5 psia (0.35 atm) and relative humidity not exceeding 15%. 2. Low temperature Four hours at a temperature of 0°F (-18°C). 3. Temperature-Pressure Chamber pressure maximum of 1.47 x 10-5 psia (10-6 atm) with temperature raised to 160°F (71°C). The temperature shall then be lowered to 0°F (-18°C) in 45 minutes and raised again to 160°F in 45 minutes. Fifteen more such cycles shall be completed. 4. Relative humidity A total time of 240 hours at temperatures varying between 68°F and 160°F (20°C and 71°C) in a relative humidity of at least 95%. The steam used must have a pH value between 6.5 and 7.5. 5. Oxygen atmosphere The test item shall be placed in an atmosphere of 100% oxygen at a pressure of 5.5 psia (0.35 atm) for 48 hours. Performance outside of specification, tolerance, visible burning, creation of toxic gases, obnoxious odours, or deterioration of seals or lubricants shall constitute failure to pass this test. The ambient temperature shall be maintained at 160°F (71°C). 6. Shock Six shocks of 40 Gs, each 11 milliseconds in duration, in six different directions. 7. Acceleration The equipment shall be accelerated linearly from 1 G to 7.25 Gs within 333 seconds, along an axis parallel to the longitudinal spacecraft axis. 8. Decompression Ninety minutes in a vacuum of 1.47 x 10-5 (10-6 atm) at a temperature of 160°F (71°C) and 30 minutes at 200°F (93°C). 9. High pressure The equipment to be subjected to a pressure of 23.5 psia (1.6 atm) for a minimum period of one hour. 10. Vibration Three cycles of 30 minutes (lateral, horizontal, vertical), the frequency of varying from 5 to 2,000 cps and back to 5 cps in 15 minutes. Average acceleration per impulse must be at least 8.8 Gs. 11. Acoustic noise 130 db over a frequency range of 40 to 10,000 Hz, duration 30 minutes.
