MIL-HDBK-2036 Military Handbook: Electronic Equipment Specifications, Preparation

The standard "MIL-HDBK-2036 Military handbook: Electronic equipment specifications, preparation" developed by the United States Department of Defense provides guidance for determining general and detailed requirements to be addressed in the preparation of specifications for electronic equipment used in shipboard (including submarines), space, mobile (vehicle) and land applications. This standard replaces the previously published standard "MIL-STD 2036A Military standard: General requirements for electronic equipment specifications".

All equipment features addressed in this standard should be considered and evaluated by the specifier during the development and adaptation of requirements. Adaptation should not be based solely on the capabilities of the equipment being procured and the specifier's subjective opinion. Rather, adaptation decisions should be based on an evaluation of the equipment mission and the equipment's anticipated operating environment based on analytical or measured field data and should reflect unique platform requirements, such as noise and hazardous material requirements for submarines and operational and maintenance requirements by personnel.

For the purposes of this standard, the definitions specified in ANSI/IEEE standard 100 apply. In addition, the following definitions also apply:

• An assembly is a set of parts or subassemblies, or any combination thereof, that can be assembled and disassembled to perform a specific function (e.g. fan assembly, audio frequency amplifier).
• Battleshort is a function that disables equipment protection and personnel safety locks to keep equipment online in high readiness states.
• A catastrophic failure is a failure that will destroy the system or subsystem and its function almost instantly.
• A classified information processing system is an electrically powered equipment, device or system that processes, transforms, reproduces or otherwise manipulates classified information in any form.
• Commercial off-the-shelf products are products that can be purchased through commercial retail or wholesale distributors, such as equipment that is available as a cataloged item.
• A component (area) is an assembly or any combination of parts, subassemblies, and assemblies that are normally capable of operating independently in a variety of situations.
• Compromising emissions are unintentional intelligence-carrying signals that, if captured and analyzed, would disclose national security information transmitted, received, processed or otherwise handled by any classified information processing system.
• Corrosion is a specific type of deterioration that results in damage or deterioration of metals or metallic parts as a result of moisture, air, acid, alkali, chemicals or electrochemical action.
• Electromagnetic interference (EMI) is electromagnetic disturbance that interrupts, interferes with, or otherwise impairs or limits the effective performance of electronic or electrical equipment. EMI can be induced intentionally, such as in some forms of electronic warfare, or unintentionally as a result of spurious emissions and responses, intermodulation products.
• Electromagnetic pulse (EMP). A transient high-intensity electromagnetic field. These pulses are most commonly associated with nuclear explosions in the atmosphere, but can also originate from other sources, such as lightning.
• Electrostatic discharge (ESD) is the transfer of electrostatic charge between objects at different potentials by direct contact or an electrostatic field.
• Emission control is a ship operational state in which acoustic, electromagnetic and optical emitters such as radars and communications equipment are blocked or limited.
• Containment is the synergistic division of the combat system, hull mechanical and electrical systems, and damage control systems into zones that can function independently to provide a subset of the ship's mission capabilities if required.
• Fully hardened is the most stringent performance criterion for a requirement. Fully hardened equipment can be off-the-shelf, ruggedized or militarized equipment.

The specifier should tailor the performance criteria to suit the applications and operating conditions in which the equipment is intended to be used. Fully off-the-shelf and ruggedized equipment is permitted for mission-critical applications, provided the equipment complies with the service and functional requirements. This standard is for guidance only and is not intended to be a requirement.
