RS 521 Training Seminar
Advanced Accelerated Life Testing Analysis

RS 521 explores advanced concepts and applications for quantitative accelerated life testing data analysis, including tests with multiple stresses or time-dependent 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.
