(1) Individual Tests
(2) Maintainability Tests
(3) Reliability Assurance Tests
( 4 ) Special Tests
4.4.1
Individual Tests - Each equipment submitted for acceptance
s h a l l be subjected to the individual tests.These tests shall be determine compliance with
the requirements of material, workmanship, operational adequacy and reliability y. As a minimum each
equipment accepted shall have passed the following tests:
(1) Examination of Product
( 2 ) Operational Test
Examination of Product - Each equipment shall be examined
4.4.1.1
carefully to determine that the material and workmanship requirements have been met.
Operational Test - Each equipment shall be operated long
4.4.1.2
enough to permit the equipment temperature to stabilize and to check sufficient characteristics and
record adequate data to assure satisfactory y equipment operation.
Maintainability Tests - The following procedure shall be used
4.4.2
to demonstrate that the time-to-repair for this equipment is as specified.
4.4.2.1
Test Conditions - One equipment shall be used for this test.
The contractor shall select any one of the equipments that is available. All dust covers shall be in
place on the equipment prior to the initiation of this test. Two technicians shall be used to conduct
these tests but only one shall be used per repair action as defined in 4.4.2.2. Before beginning the
test, the equipment shall be checked to determine that it is operating normally. Test equipment, tools,
spare parts, diagnostic programs, and documentation shall be available for the test. The test facility
shall be provided by the procuring activity. The diagnostic program shall be the primary means of
fault detection and isolation.
4.4.2.2
Repair Actions - A repair action shall be as follows:
(1) Final Fault Isolation after completion of the Diagnostic
Program.
(2) Repair
(3) Equipment Checkout
4.4.2.3
Simulated Failures - A total of 100 failures one at a time shall
be introduced into the DPS. The failures shall be randomly introduced into the DPS The failures
shall be randomly introduced throughout the equipment. The points of failures shall be approved by
the procuring activity prior to initiation of the test.
Inducing Failures - Single failures shall be induced into the
4.4.2.3.1
equipment by the government representative by substituting modules that are known to be defective.
Simulated failures using other means may be used but they shall be kept to a minimum. Each demon-
strated failure will consist of a single solid malfunction.
4.4.2.4
Repair Time Measurements - The time required for the tech-
nician to perform each repair action, including the use of technical manuals and support equipment,
shall be measured starting with final fault isolation after completion of the Diagnostic Program and
ending at the time the equipment is restored to normal operation and proper operation is verified.
Any delay, such as waiting for parts, obtaining test equipment, or administrative delays shall be
excluded.
