ROCKY MILITARY GRADE, FULLY RUGGED COMPUTERS DESIGNED TO MEET THE TOUGHEST STANDARDS
MIL-STD 810F, MIL-STD 461E, and IEC IP54 & IP-65 Test Standards and Specifications
AMREL's ROCKY military grade, fully rugged computers have been specially designed to meet and exceed the toughest military standards for durability. The ROCKY fully rugged notebooks, fully rugged tablets, and fully rugged PDAs have been certified to MIL-STD 810F for ruggedness and MIL-STD 461E for electromagnetic interference shielding. Built to resist rain, shock, vibration, dust, humidity, salt fog, and extreme temperatures, ROCKY rugged computers will withstand and perform in the most abusive and relentless environments on earth.
To learn more details about of each these tests, their methods, and procedures, please reference the specific section below:
Specific models such as the RK (15 inch rugged notebook) and DR (8 inch rugged tablet) underwent additional relentless testing for explosion proof and solar radiation inhibition. Moreover, the DA series of fully rugged PDAs are officially IEC IP65 certified. These particular models passed several additional tests for ruggedness, and all passed with flying colors. |

MIL-STD 461E (EMI)
Electromagnetic Interference Test (EMI)
Military Standard 461E establishes design requirements for the control of electromagnetic interference and susceptibility characteristics of electronic, electric, and electromechanical equipment and subsystems designed or procured for use in activities by agencies in the Department of Defense.
All AMREL rugged military notebooks, tablets, and PDAs meet the certification requirements of:
(CE102, CS101, CS114, CS115, CS116, RE101, RE102, RS101, RS103)
- FCC, Part 15 Class B
- Safety – UL, TUV, CE, E-Mark markings
