Letters correspond to the steps in the
following
list.
There are three thermal cycles identified in the procedure of F.1.11.3:
1st thermal cycle is steps a

.
a)
Start at
a temperature between 4 °C and 50 °C (between 40 °F and 120 °F)
with atmospheric pressure
and raise temperature to the maximum.
b)
Apply
the
test pressure, hold for a minimum period of
1
h,
and
then release
the
pressure.
c)
Lower temperature to the minimum.
d)
Apply
the
test pressure,
hold for a minimum period of 1 h, and then release the pressure.
e)
Raise the temperature to
a temperature
between 4 °C and 50 °C (between 40 °F and 120 °F)
.
f)
Apply the test pressure at
a temperature between 4 °C and 50 °C (between 40 °F and 120
°F)
and
maintain at 50
% to 100
% of test pressure while raising temperature to the maximum.
g)
Hold
for a minimum period
of 1 h at test pressure.
h)
Reduce the temperature to the minimum while maintaining 50
% to 100
% of test pressure.
i)
Hold for a minimum period of
1
h at test pressure.
j)
Raise the temperature to
a temperature between 4 °C and 50 °C (between 40 °F and 120 °F)
wh
ile
maintaining 50
% to 100
% of test pressure.
k)
Release the pressure, then raise the temperature to the maximum.
l)
Apply the test pressure, hold for a minimum period of
1
h, and then release the pressure.
m)
Reduce the temperature to the minimum.
n)
Apply the test
pressure, hold for a minimum period of
1
h, and then release the pressure.
o)
Raise the temperature to
a temperature between 4 °C and 50 °C (between 40 °F and 120 °F)
.
p)
Apply the test pressure, hold for a minimum period of
1
h, and then release the pressure.
q)
Apply 5
% to 10
% of the test pressure, hold for a minimum period of
1
h, and then release the pressure.
