designed to operate, and the specific requirements which must be observed
during installation and use of the equipment. Where adequate, the use of
vendor supplied documentation is encouraged. The contracting activity shall
ensure that vendor supplied documentation is accurate and complete, as
documentation is of utmost importance in military systems. Documentation
requirements for hazardous materials are specified in 4.7.2
.
4.3.3.2.1.1 Proprietary information. The program manager shall ensure that
the Government's interests are protected with respect to vendor proprietary
information concerning equipment. In the event an equipment is removed from
production or deleted from the vendor's catalog, data rights and the right to
other proprietary information shall be transferred to the Government at the
time maintenance support is discontinued by the vendor.

accordance with IEEE 268.
4.3.3.2.1.2.5 Terminology. The vocabulary and terms used to describe
electronic systems shall be in accordance with IEEE 100.
4.3.3.2.2 Maintainability and reliability. Quantitative maintainability
requirements in terms of MTTR shall be specified. Quantitative reliability
requirements in terms of basic reliability and mission reliability shall be
specified. Guidance on maintainability program requirements is provided in
SECNAVINST 4490.2. Guidance on reliability program requirements is provided in
MIL-STD-785. The determination of quantitative maintainability and reliability
requirements for COTS and ruggedized equipment shall be the responsibility of
the program manager. Analytical, field experience or test data shall be
required as evidence of achievement of reliability.
4.3.3.2.3 Operational availability. Requirements shall be specified for
operational availability in the end item specification. Guidance is provided
in OPNAVINST 3000.12.
4.3.3.2.4 Testability. Testability shall be as specified
herein.
4.3.3.2.4.1 Test provisions. Test provisions shall be provided
for monitoring performance, calibration, and fault isolation in accordance
with requirement 32 of MIL-STD-454. The test provisions of the equipment shall
provide the capability for a straight forward, logical, step-by-step testing
sequence, as well as providing for an end-to-end performance check. The
specific test capability and class of test provisions shall be as specified in
the end item specification.
4.3.3.2.4.2 Test equipment and built in test devices. Test equipment and
built in test devices required for calibration, operation, and maintenance
shall be tailored from MIL-T-28800. Design for testability shall be tailored
from MIL-STD-2165. Test equipment calibration requirements shall be tailored
from MIL-STD-1839 and MIL-STD-45662.
4.3.3.2.4.3 Test cables. Test cables and extender cards shall be provided
and fitted with connectors to allow removable subassemblies to be electrically
reconnected for maintenance.
4.3.3.2.4.4 External test points. Protection shall be provided in the test
point circuitry to prevent equipment damage caused by the external grounding
of test points.
4.3.3.2.4.5 Special tools. Special tools shall kept to a minimum and shall
be in accordance with MIL-STD-454, requirement 63. Special tools are defined
as those tools not listed in the Federal Supply Catalog (copies of this
catalog may be consulted in the office of the Defense Contract Management Area
Operations (DCMAO)).
4.3.3.2.5 Level of repair analysis. Level of repair guidance is provided in
MIL-STD-1390.
4.3.3.2.6 Training. Training requirements shall be determined for the
proper and safe use, operation, maintenance, and repair of the system
equipment and software. Consideration shall be given to on-line and built-in
training helps, aids, tutorials, and other instructional media. The use of
vendor and/or crew developed training is encouraged. Vendor developed training
shall be used in accordance with OPNAVINST 1500.2 and MIL-STD-1379, when
appropriate. Vendor developed training shall be integrated in Chief of Naval
Education and Training (CNET) curricula in accordance with OPNAVINST 1500.8
and OPNAVINST 1500.44.

4.3.3.4 Interchangeability. Interchangeability shall be in accordance with
MIL-STD-454, requirement 7. Interface performance specifications shall be
provided for interchangeable items as part of the item documentation specified
in 4.3.3.2.1. System software shall be "reusable" in accordance with
DOD-STD-2167 in the same sense as interchangeability is applied to hardware
items. Re-engineered items shall be backward compatible as a minimum. Items,
other than maintenance parts, from different sources of supply may be
designated as "fully interchangeable."
