Low Pressure
Method 500.5
Procedure II - Operation/Air
Carriage
Decrease pressure to 57.2 kPa (equivalent to 15,000
feet) at a rate not to exceed 10 m/s at a temperature of
23ºC ±3ºC and hold for 1 hour.
High Temperature
Method 501.5
Procedure I – Storage
Over 24 hours, cycle the unit from 35ºC to 71ºC and
back to 35ºC. Repeat 7 times.
High Temperature
Method 501.5
Procedure II - Operation
This test is a subset of the High Temperature test
(Method 500.5, Procedure – I) in which the operation is
verified at 71ºC over the first 3 cycles of Procedure I.
Low Temperature
Method 502.5
Procedure I – Storage
