scope:

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.

This handbook explains techniques for use in reliability tests performed during the integrated test programs specified in MIL-STD-785. Procedures, plans, and environments which can be used in Reliability Development/Growth Tests (RD/GT), Reliability Qualification Tests (RQT), and Production Reliability Acceptance Tests (PRAT) are discussed. In addition, Environmental Stress Screening (ESS) methods are provided.

Data provided in this handbook can be used selectively on reliability test programs and can be specified in Department of Defense contracted procurements, requests for proposals, statements of work, and Government in-house developments which require reliability testing.

The data provided herein can be selected for use on tailored reliability test programs as required by governing regulations and as appropriate to the particular system or equipment, intended application, program type, magnitude, and funding.

When referencing the test methods, test plans, and environmental test conditions of this handbook, the handbook and the specific paragraph number(s) are to be cited.
