Highly accelerated life testing (HALT): A review from a statistical perspective

WIREs Computational Statistics
Despite its use in one form or another for at least four decades, HALT and related techniques [e.g., highly accelerated‐stress screening (HASS) and stress audits (HASA)] are not well understood within the statistical community and remain controversial ...

Accelerated Life Testing of Capacitors

IRE Transactions on Reliability and Quality Control, 1957
One of the problems facing the designer of modern electronic communication systems is the ultimate reliability to be achieved under service conditions. The required level of reliability together with the unavoidable complexity of present-day equipment calls for components having extremely low failure rates.

Model-Robust Test Plans With Applications in Accelerated Life Testing

Technometrics, 2003
We study a criterion based on a weighted asymptotic sample ratio (ASR) that yields model-robust test plans with relatively low ASRs under different models. We apply the criterion to accelerated life test planning in which interest lies in estimating life quantiles and there is uncertainty as to whether the Weibull or the lognormal model best describes ...

Estimation for a weibull accelerated life testing model

Naval Research Logistics Quarterly, 1984
AbstractIt is sometimes reasonable to assume that the lifetime distribution of an item belongs to a certain parametric family, and that actual parameter values depend upon the testing environment of the item. In the two‐parameter Weibull family setting, suppose both the shape and scale parameters are expressible as functions of the testing environment.

Accelerated Life Tests at Higher Usage Rates

IEEE Transactions on Reliability, 2005
Accelerated life tests are extensively used to provide quickly the information about the life distributions of products. Test units are subjected to elevated stresses which yield shorter lives. For some products whose life is defined by usage, e.g., mileage and cycles, test units are also run at higher usage rates (UR) to compress the test time.

Optimum step‐stress for temperature accelerated life testing

Quality and Reliability Engineering International, 2007
AbstractStep‐stress accelerated life testing is a design strategy where the stress is modified several times during the test. In this work we address the problem of designing such a test. We focus on temperature accelerated life testing and we address the problems of setting the step duration and the stress levels.
