b. Perform all tests in accordance with instructions furnished in the manufacture's manual for the test bench (para 8
a). Operation, Maintenance, Overhaul and parts list manual relative to the test bench cannot be obtained through AG
Publications channels but must be requisitioned through normal supply channels.
Compressors having over 501 psi (35.2 kg/sq cm) discharge pressure shall be tested at least 300
feet (91.5 m) from unbarricaded critical equipment or inhabited buildings. Unprotected personnel
shall be at least 300 feet (91.5 m) from test site.
c.
Equipment required is as follows:
(1) Test benches (Section III).
(2) A barricade or equivalent protection for the inspector during the over pressure period of the test.
d. Prior to performing the test specified in b above, all safety valves and other protective devices such as rupture
disks and vacuum valves, where used, shall be visually checked to determine the physical condition of these items and to
ensure that air through the discharge headers and outlets is not restricted by corrosion or other foreign material. If
possible, all unloading devices shall be manually tripped during this inspection.
e. A service hose in storage, intended for use at a pressure exceeding 501 psi (35.2 kg/sq cm), shall be considered
as having a maximum total life of 5 years. All hoses with a test date older than 12 months shall be forwarded to the
nearest maintenance activity which has a testing facility for retest prior to issue or return to stock. Hose that fails the test
shall be disposed of immediately.
f. The periods for inspection referred to above are applicable to compressors in operation with normal shutdown
intervals. If the compressor is out of service for an extended interval, the effect of this change in condition may be
considered in revising the date of the next inspection. The compressor shall be given an operational test as a unit at the
time of issue from the depot if it has been out of service for a continuous period of one year or more and shall be
operationally tested by direct support prior to issue to troop units. After issue, all compressors (501-6000 psi (35.2-421.8
kg/sq cm)) shall be tested annually by the appropriate direct support activity in accordance with the following:
(1) Perform all tests as specified in a and b above. Reinstall the tested components.
(2) Make a detailed visual inspection of the entire unit. Particular attention shall be given to the exterior
condition of receivers, intercoolers, aftercoolers, gages, unloaders, relief devices, fitting, valves, hoses, etc.
