MIL-PRF-22885/13K
REQUIREMENTS:
Dimensions and configuration: See figure 1.
Classification: See MIL-PRF-22885/9.
Weight: .15 ounce maximum.
Seal: Dripproof (enclosure design 2).
Sunshine test: With the boot properly assembled to the 4-lamp modular indicator light (or to the 4-lamp illuminated
push switch) the boot shall be subjected to the solar radiation (sunshine test), MIL-STD-810,
method 505, procedure I, using the basic hot diurnal cycle. At the completion of the test the boot shall be compared
to untested boots. There shall be no more than 10 percent change in window transmittance after the completion of
the test; nor shall there be any crazing or cracking.
Mechanical endurance: 5,000 cycles at -55°C; 10,000 cycles at +71°C ±2°C; 35,000 cycles at +25°C ±2°C. All four
lamps shall be continuously energized at their maximum rated voltage during cycling at the +71°C ±2°C and +25°C
±2°C conditions. MIL-DTL-6363/8-5 lamps (or industry equivalent) shall be used. Following this test, the legends
shall be legible and there shall be no cracking or crazing of the boot.
Marking: Identification marking shall be on unit package or tag.
Part or Identifying Number (PIN): M22885/13-02. PIN M22885/13-01 (with polyvinyl chloride window and stainless
steel mounting adapter) has been canceled and replaced by M22885/13-02.
Group A inspection: Shall be in accordance with table I. The sampling plan shall be in accordance with
MIL-PRF-22885.
Qualification and group B inspection: Required as part of the 4-lamp illuminated push button switch
MIL-PRF-22885/9). Qualification and group B inspections shall consist of the inspections specified in table II.
Intended use: As dripproof panel seal boot for 4-lamp illuminated push switch, MIL-PRF-22885/9 or for 4-lamp
modular indicator light, MIL-PRF-22885/10.
