Abstract

This handbook provides test methods, test plans, and test environmental profiles which can be used in reliability testing during the development, qualification, and production of systems and equipment. <br>This handbook explains techniques for use in reliability tests performed during integrated test programs. Procedures, plans, and environments which can be used in Reliability Development/Growth Tests (RD/GT), Reliability Qualification Tests (RQT), Production Reliability Acceptance Tests (PRAT), Environmental Stress Screening (ESS) methods, and Durability/Economic Life Test are provided. <br>Data provided in this handbook is typical of reliability test programs and may be specified in Department of Defense contracted procurements, requests for proposals, statements of work, and Government in-house developments which require reliability testing. This handbook is for guidance only. This handbook cannot be cited as a requirement. If it is, the contractor does not have to comply <br>When referencing the test methods, test plans, and environmental test conditions, the source is to be cited. <br>The methods in this handbook are applicable to six broad categories of equipment, distinguished according to each equipment's field service application: <br>Category 1. Fixed-ground equipment <br>Category 2. Mobile ground equipment <br>A. Wheeled vehicle <br>B. Tracked vehicle <br>C. Shelter configuration <br>D. Manpack <br>Category 3. Shipboard equipment <br>A. Naval surface craft <br>B. Naval submarine <br>C. Marine craft <br>D. Underwater vehicle <br>Category 4. Equipment for jet aircraft <br>A. Fixed-wing <br>B. Vertical and Short Takeoff and Landing (V/STOL) <br>Category 5. Turboprop aircraft and helicopter equipment <br>A. Turboprop <br>B. Helicopter <br>Category 6. Missiles and assembled external stores <br>A. Air-launched missiles <br>B. Assembled external stores <br>C. Ground-launched missiles <b><u>Intended Use:</u></b> General application. <br>
