2)
Visual Examination:
Examine each sterilizer for the following
defects:
a)
Materials not as specified, and obviously damaged,
defective, or not properly suited for purpose intended.
b)
Component parts, assemblies, accessories, and spare parts
for sterilizers of the same classification are not
interchangeable.
c)
Design not as specified. Not incompliance with applicable
codes and standards.
d)
Components not easy accessible for maintenance and
servicing. Safety devices not provided as specified.
e)
Controls and indicators missing or not as specified.
f)
Sterilizers not install as specified.
g)
Power supply not as specified.
h)
Metal used in fabrication not type specified. Has sharp
corners, burrs, dents, and deformities.
i)
Bolted connections not as specified. Missing, stripped, or
cross-threaded screws, bolts and nuts.
3)
Operational Test:
Set temperature controller at 120 C (250 F)
-
Step 1
and timer for 30-minute sterilizing phase.
Start sterilizer and measure and record time
for chamber temperature to rise to 120 C - 123 C
(250 F - 254 F) as shown on temperature indicator.
Permit sterilizer to complete cycle.
-
Reduce sterilizer chamber to ambient pressure.
Step 2
Set temperature controller at 132 C (270 F) and
-
Step 3
timer for 30-minute sterilizing phase. Start
sterilizer and measure and record time required
for chamber temperature to rise to 132 C - 134 C
(270 C - 274 F) as shown the temperature indicator.
Permit sterilizer to complete cycle. Finally reduce
chamber to ambient pressure.
-
Remove chart from recorder, check time and
Step 4
temperature with the contract specifications and/or
manufacturers standards.
4)
Fast Exhaust Efficiency Test: With no load in the chamber,
operate the sterilizer to achieve chamber temperature of
132 C - 134 C (270 F - 274 F). The actuate the fast exhaust
selector and measure the time required to reduce the chamber
pressure to zero as shown on the chamber pressure gauge. The
time required to reduce the sterilizing chamber pressure to zero
should not exceed three minutes.
