SYSTEM COMPLIANCE

MIL-STD-740-1: Airborne Sound Measurements for Shipboard Equipment

MIL-STD-740-2: Structureborne Vibratory Acceleration Measurements

Additional Ruggedization to meet MIL-S-901, MIL-STD-167, MIL-STD-810, and DOD-STD-1399: The System’s construction is extremely robust, and ruggedized throughout. All components and modules within the unit are mounted using additional steel brackets and heavy-duty stainless-steel hardware, which is then further secured using Loctite and RTV where required. All boards are conformal-coated (Acrylic MIL-I-46058 Type R) for maximum resistance to potential condensation and fungus growth.

DOD-STD-1399 Section 301A Table V – Design Limits for Ship Motion

Internal EMI Reduction Package to meet MIL-STD-461: The design of this unit is specifically focused on reducing EMI emissions. The unit contains substantial internal filtering to minimize EMI emissions. Inputs which may be susceptible to transients are protected by several methods. The compact rack mount chassis is specifically treated with low surface resistivity finishes on the interior. All aluminum parts are treated with clear irridite. The steel parts are treated with zinc plate, followed by a clear chromate. Paint method via ANSI-61 gray is designed to assure excellent bonding of mating sheet metal parts. All input and output ventilation filters include metal honeycomb-style or mesh filters.
