Applicable paragraphs
of MIL-S-22518A(AS)
4.5.11.2
High Temperature Operation:
Starter:
The inlet air pressure and temperature
and the stabilized ATS/AD temperatures for the
high temperature test shall be as follows:

After the ATS/AD temperature has been stabilized
for a minimum of 8 hours at +160F, three con-
secutive cycles at a +160F ambient air temperature
shall be run.  Each cycle shall be as specified
for phases A, B, and C of 4.5.11.1.
Accessory Drive:  After a minimum 8-hour soak
period at an ambient air temperature of +250F,
the ATS/AD shall be operated with ambient air
at 250 F minimum at 7000 RPM speed at pad "A"
drive for a period of 30 minutes.  A 10 HP con-
tinuous load shall be applied at pad "B." except
for 2.5 minutes when a load of 32 HP shall be
applied.  This 30-minute cycle of operation
shall be repeated until 10 hours of operating
time are accumulated.
No. of cycles: 5
4.5.12
Consecutive Cycle Operation:
4.5.14
Vibration:  All vibration testing shall be conducted
with the specified accessory or a dummy, having
a weight of 17.4 pounds and-a center of gravity
4 inches from the-mounting face, mounted on the
accessory pad (pad "B") .  Mounting shall be
dynamically similar to that encountered in service
use.  Vibration tests shall be conducted in accordance
with MIL-STD-810, Method 514, Procedure I, Curve F
(Parts 1, 2, and 3).  In addition, the ATS/AD shall
be capable of withstanding a loading of 10g bending
moment applied at the ATS/AD e.g. in any direction
without structural damage.
