4.6.1.8 Acoustic Noise - The WDC shall be subjected to acoustic noise
in l ccordance with MIL-STD-810, Method 515. with the overall sound pressure
level of Table I. The functional tests shall be conducted during this test.
4.6.1.9 Salt Atmosphere - The WDC shall be tested in accordance with
MIL-STD-810, Method 509, Procedure I.
4.6.1.10 Sand and Dust - The WDC shall be subjected to sand and dust
when nonoperating, in accordance with MIL-STD-810, Method 510, Procedure I.
The functional test shall be performed prior to and after exposure to sand
and duet.
4.6.1.11 Explosive Atmosphere - The WDC shall be tested in accordance
with the test requirements of MIL-STD-81O, Method 511, Procedure I. The
functional test shall be performed during the exposure to the explosive
environment . In lieu of testing, a certification that the WDC meets the
explosion-proof requirement of 3.3.9,9 may be submitted.
4.6.1.12 Fungus Test - A certification that the requirements for fungus
inert materials and components have been met may be submitted in lieu of
performing a fungus test.
4.6.1.13 Warm-up Time - The preproduction WDC shall be tested to verify
that the requirements of 3.3.10 are met.
4.6.1.14 Operating Power - The preproduction WDC shall be tested under
worst case combinations of the input power conditions to verify compliance
with the requirements of 3.3.11
.
4.6.2 Operational Tests - Each WDC shall be subjected to the operational
tests specified herein, as listed in Table VIII.
4.6.2.1 Memory Cross Temperature Read-Write Capability - Memory data
shall be stored at -40C and read at +60C and vice-versa to l ssure compliance
with the requirements of 3.4.1.1.3. The WDC shall be stabilized at each
temperature extreme prior to conducting the read-write operations.
.
4.6.2.2 Input Power - The total input powez to the WDC shall be measured
and recorded at ambient temperature and at -40C and +60C.
4.6.2.3 Addressability - Contiguous addressability from 0000 to 3FFF
hexadecimal shall be verified by 4.6.2.7. Contiguous addressability from
3FFF to 7FFF shall be verified.
.
4.6.2.4 Memory Protection/Eloctric~ Transients - The WDC shall be
subjected to all extremes of electrical power and power transients as specified
in 3.3.11.2 and 3.3.11.3 with the exception of transients with a duration of
less than 75 us. Verification that the requirements of 3.4.1.1.4, 3.3.11.2,
3.3.11.3, and 3.3.11.4 are met shall be demonstrated through the execution of
