3. REQUIREMENTS

3.1 Design and construction.

3.1.1 General. The equipment shall meet the requirements of best manufacturing practice except as specified

herein. The design objectives of a high-strength-to-weight ratio, reliability, simplicity, ease of installation and

maintenance consistent with the need of the military service, shall be considered during all phases of equipment

design and construction.

3.1.2 Service conditions.

3.1.2.1 Temperature. The equipment shall meet the temperature requirements for exposed - unsheltered (ship or

shore) operating temperature range -54�C to +65�C and non-operating temperature range -62�C to +71�C.

3.1.2.2 Wind load. The equipment shall be capable of withstanding a 120-knot wind.

3.1.2.3 Salt atmosphere. The equipment shall be capable of operating without failure for a period normal to

similar electronic equipment aboard ship, without being adversely affected by humid salt atmosphere.

3.1.2.4 Inclination, vibration, and shock. The antenna, its mounting, and representative structure for its mounting

(what is important to simulate the installation) shall meet the applicable inclination, vibration, and shock requirements

of 4.4.1, 4.4.2, and 4.4.3. For inclination requirements of 4.4.1, shipboard equipment shall operate in all attitudes

encompassed by DOD-STD-1399-301. A shock spectrum and transient duration shall be defined which represents

extreme design conditions to be encountered and the shock test levels for use in 4.4.3.

3.1.3 Construction. Equipment shall be constructed to conform to the service conditions as specified herein.
