Reliability growth. Stress testing for early failures in unique complex systems has-hardcopy This International Standard specifies a1 Scope This International Standard gives guidance for reliability growth during final testing or acceptance testing of unique complex systems. It gives guidance on accelerated test conditions and criteria for stopping these tests. Unique means that no information exists on similar systems, and the small number of produced systems means that information deducted from the test has limited use for future production. This standard concerns reliability
