ABSTRACT

Accelerated life testing (ALT) is performed by testing specimens under more severe conditions than encountered during normal operational conditions. That is, more severe values of stressors such as pressure, temperature, etc, are used. Based on the test results, relevant reliability parameter(s) under operational conditions are estimated.

The paper presents some possibilities and limitations in the use of multivariate analysis in ALT. References to theory, and examples from practical applications, are given. A list of references from a literature survey is included.
