MIL-PRF-83287G
3.11 Terminal strength (indicators with solder terminals only). When indicators are tested as specified in 4.5.8,
there shall be no breakage, loosening, or rotation of the terminals, and the indicators shall function properly.
3.12 Shock (specified pulse). When tested as specified in 4.5.9, indicators shall not malfunction or false transfer
(see 6.6) in the "Fault" and "No Fault" positions and shall meet the operating voltage requirement (see 3.7).
3.13 Vibration, high frequency. When tested as specified in 4.5.10, indicators shall not exhibit damage and shall
meet the operating voltage requirement (see 3.7). Indicators shall not malfunction or false transfer.
3.14 Salt spray (corrosion) indicators with metallic bodies only. When tested as specified in 4.5.11, indicators shall
not exhibit corrosion, peeling, chipping, or blistering of the finish or exposure of base metal, and shall meet the
operating voltage requirement (see 3.7).
3.15 Moisture resistance. When tested as specified in 4.5.12, indicators shall not exhibit breaking, cracking, or
chipping of the finish and shall meet the dielectric withstanding voltage (see 3.6), operating voltage (see 3.7), and dc
coil resistance (see 3.8) requirements.
3.16 Resistance to soldering heat (indicators with solder terminals only). When tested as specified in 4.5.13,
indicators shall function properly.
3.17 Magnetic susceptibility. When tested as specified in 4.5.14, indicators shall not malfunction or false transfer.
3.18 Electromagnetic interference. When tested as specified in 4.5.15, indicators shall not malfunction or false
transfer.
3.19 Random vibration. When tested as specified in 4.5.16, indicators shall not malfunction or false transfer.
Indicators shall not exhibit damage and shall meet the operating voltage requirement (see 3.7).
3.20 Barometric pressure (reduced). When tested as specified in 4.5.17, indicators shall withstand the test voltage
specified with no evidence of damage due to arcing, flashover, or insulation breakdown.
3.21 Solderability (indicators with solder terminals only). When indicators are tested as specified in 4.5.18, the
solder terminals shall be evaluated as specified for lugs in method 208 of MIL-STD-202.
3.22 Life. When tested as specified in 4.5.19, indicators shall not malfunction and shall meet the operating voltage
requirement (see 3.7).
3.23 Marking. Marking of indicators shall conform to method I of MIL-STD-1285, and shall include the military PIN
and manufacturer's source code. The date code and dc rated voltage shall also be included. In addition, indicators
with solder terminals shall be marked as specified (see 3.1). Terminal identification shall be adjacent to the terminal
so as to properly identify each terminal.
3.24 Workmanship. Indicators shall be processed in such a manner as to be uniform in quality and shall be free of
cracks, chips, sharp edges, and burrs. Indicators shall be free from defects that will affect life, serviceability,
performance or appearance.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.3).
b. Conformance inspection (see 4.4).
4.1.1 Test equipment and inspection. Test and measuring equipment and inspection facilities of sufficient
accuracy, quality and quantity to permit performance of the required inspection shall be established and maintained
by the contractor. The establishment and maintenance of a calibration system to control the accuracy of the
measuring and test equipment shall be as specified in ISO-10012-1 and NCSL-Z540.1 or equivalent as approved by
the qualifying activity.
