For the Rubber and Plastics cycle, the
theoretical cassette temperature calculated from
the measured cassette pressure was below the
sterilization temperature, allowing for
measurement error (i.e. Pchm < 204.8 kPa).
• Calibration imbalance (pressure
transducer or chamber thermocouple)
• Poor air removal during conditioning
(exhaust blockage).
• Not able to generate steam
•
55
For the Rubber and Plastics cycle, the
theoretical cassette temperature calculated from
the measured cassette pressure was more than
4°C above the sterilization temperature, allowing
for measurement error (i.e. Pchm > 232 kPa).
• Calibration imbalance (pressure
transducer or chamber thermocouple)
• Sticking solenoid valve (closed)
• Failed solenoid coil
• Blocked cassette exhaust duct
• Obstructed exhaust tubing (kink)
•

For a 134°C cycle, the chamber temperature
dropped below the sterilization temperature,
allowing for measurement error (i.e. Tchm <
134°C).
• Poor air removal during conditioning
(exhaust blockage).
• Not able to generate steam
• Steam leak in the system
61
For a 134°C cycle, the chamber temperature
rose more than 4 C° above the sterilization
temperature, allowing for measurement error
(i.e. Tchm > 138°C).
• Sticking solenoid valve (closed)
• Failed solenoid coil
• Blocked cassette exhaust duct
• Obstructed exhaust tubing (kink)
62
For a 134°C cycle, the theoretical chamber
temperature as calculated from the measured
chamber pressure was more than 2°C below the
measured chamber temperature, allowing for
measurement error.
• Calibration imbalance (pressure
transducer or chamber thermocouple)
• Sticking solenoid valve (closed)
• Failed solenoid coil
• Blocked cassette exhaust duct
• Obstructed exhaust tubing (kink)
• Poor air removal
