Environmental Requirements

3.1

Temperature and Altitude
The MA11M complies with the temperature-altitude tests per MIL-STD-810C, Method 504, and Procedure 1
Equipment Category 5.

3.2

Explosive Atmosphere
The MA11M is designed for operation in the presence of explosive mixtures of air and jet fuel without causing
explosion or fire at atmospheric pressures corresponding to altitudes from -1,800ft to 50,000ft. The MA11M does
not produce surface temperatures or heat in excess of 400F. The MA11M does not produce electrical discharges
at an energy level sufficient to ignite the explosive mixture when the equipment is turned on or off or operated. The
MA11M meets the requirements of MIL-STD-810C, Method 511.1, and Procedure II. Hermetically sealed
equipment meeting the Requirements of MIL-STD-202, Method 112D, or MIL-STD-883, Method 1014.7 (asapplicable), and not exceeding a Helium leakage rate of 1 x 10-7 cc/sec, are exempt from this requirement.

3.3Salt Fog
The MA11M is designed to meet the requirements of Salt Fog conditions per Paragraph 3.2.24.9 of MIL-E-5400
and MIL-STD-810C Method 509.1. The MA11M is designed to withstand a salt concentration of five percent at atemperature of 35C for 48 hours without degradation.

3.4

FungusThe MA11M is designed to meet the requirements of fungus conditions per Paragraph 3.2.24.8 of MIL-E-5400 andMIL-STD-810C Method 509.1 i.e. fungus inert materials per Requirement 4 of MIL-HDBK-454.

The MA11M is designed to meet the performance standards per RTCA-DO-160E Paragraph 4.6.2 Category D
during and following a rapid and complete loss of normal cabin compartment pressurization (10,000 feet) from anairplane flight altitude of 50,000 feet within 15 seconds. The MA11M will remain operating for five minutes at
50,000 feet before being returned to normal cabin pressure.

3.8

Overpressure
MA11M is designed to be capable of withstanding, for 10 minutes, while not operating, a 12.1psi compartmentpressure with no physical distortion or permanent set per RTCA-DO-160E Paragraph 4.6.3. The MA11M will
operate satisfactorily upon return to normal pressure.

3.9

Flammability
The MA11M is self-extinguishing or nonflammable and is designed to meet the Requirements of Paragraph 5.2.4
of MIL-STD-1587 and Requirement 3 of MIL-HDBK-454.

3.11

Finish and Colors
All case surfaces of the MA11M are treated with chemical film per MIL-DTL-5441, Type II, Class 3. The MA11M
bottom contact surface is free of paint or non-conductive finishes. The MA11M bottom contact surfaces areprotected from corrosion by a conductive coating (MIL-DTL-5541). All other surfaces, except connector matingsurfaces are primed per MIL-PRF-23377, Type 1 Class C and painted per MIL-PRF-85285, Type 1 Color Number(26231), Military Gray (not lusterless variety) per FED-STD-595 (Exceptions: bottom and connector surfaces arefree of paint).

3.12

Human Factors
Human Engineering principles and criteria (including considerations for human capabilities and limitations) using
MIL-STD-1472 in all phases of design, development, testing, and procedures development. The design is free ofall sharp edges, according to MIL-STD-1472.

3.13

Shock
The MA11M is designed to withstand the shock levels specified in the saw tooth shock pulse parameter specified
in Figure 3-1 and Table 3-1.
