MIL-C-18244A(WEP)

4.3.2

Scope of Tests - Preproduction tests shall consist of at least the

following series of accelerated tests to determine reliability and performance under the various

conditions which may be encountered in service usage. The preproduction tests may be allocated

among the three test systems or components. A suggested order of tests is as follows:

Breakdown of tests where additional or a different quantity of systems or components is allocated

for preproduction test shall be as specified in the contract or detailed specification.

Contractor Testing - With the consent or request of the contractor and at the

4.3.3

discretion of the procuring activity, any service condition tests conducted by the contractor and

witnessed by an authorized procurement activity representative prior to submission for preproduc-

tion approval maybe acceptable as preproduction tests.

Test Tolerances - In conducting service condition tests, performance tolerances

4.3.4

shall be as specified in the system or component specification.

4.3.5

Test Procedures - Appropriate environmental tests shall be conducted on all

components which are subject to deterioration or malfunction due to any environmental condition.

Environmental testing shall be conducted on system components in accordance with Specification

MIL-T-5422 or Specification MIL-E-5272 as required by the equipment detail specification, Modifi-

cation of test procedures shall be submitted for review and approval by the procuring activity prior

to actual usage.

Power Supply Variation - Each component shall be tested individually or

4.3.5.1

assembled, or both, into a system in a manner as specified in the component or system specification.

Rated electrical, hydraulic and other required power sources, shall be applied and all calibration

setting placed at maximum rated positions. After completion of the warm-up period, the power

sources shall be varied and modulated, throughout their specified limits. The performance of the

components shall be observed in the reamer defined in the component or system specification. No

steady state nor transient modulation changes in the power source, within permissable limits, shall

cause a variation or modulation in the systems performance which may result in undesirable or

unsatisfactory operation. With rated power applied, the systems switches, controls and components

shall be operated as in actual service. Observation of the rated power source shall note no variation

nor modulation of the power source beyond permissible operational limits when the system is operated

against load conditions varying from no load to full load conditions.
