RS 521 Training Seminar
Advanced Accelerated Life Testing Analysis

3 Days     2.1 CEUs     3 CRP Credits
Assumes completion of RS 401 and RS 402 or equivalent knowledge.

RS 521 explores advanced concepts and applications for quantitative accelerated life testing data analysis, including tests with multiple stresses or time-varying stresses. ReliaSoft’s ALTA PRO software is used for hands-on practical examples. Topics include accelerated test design considerations and life-stress relationship models for a single constant stress, multiple stresses or stresses that vary with time.

The course presents concepts and software tools that you could use to help your organization:

  • Significantly reduce the test time required to obtain reliability metrics for a product, which can result in faster time-to-market, lower product development costs and improved designs.
  • Understand and quantify the effects of stress (or other factors) on product life.
  • Design accelerated tests that will be the most effective to achieve desired objectives.
