Engineers and managers involved with product development are constantly challenged to reduce time to market, minimize warranty costs, and increase product quality. With less and less time for testing, the need for effective accelerated test procedures has never been greater.
This course covers the benefits, limitations, processes, and applications of several proven accelerated test methods including accelerated reliability, step stress, FSLT (Full System Life Test), FMVT® (Failure Mode Verification Testing), HALT (Highly Accelerated Life Testing), and HASS (Highly Accelerated Stress Screening). It is designed for anyone involved in product design, life testing, reliability testing and validation for passenger cars, light trucks, heavy duty, off-highway or aerospace vehicles, including reliability engineers, validation engineers, design engineers and their managers. Users or purchasers of testing or engineering services will also find this course to be valuable.
Based on the popular classroom seminar, this course offers more than 10 hours of instruction divided into fourteen modules; a coordinated handbook; and a copy of the instructor's book, Accelerated Testing and Validation Management, which includes numerous hands-on exercises and a CD with analytical spreadsheets.
Major topics include:
- Statistical Limitations and Innovation vs. Commodity

- Overcoming Life Prediction Limitations in HALT and FMVT
- Review the details of setting up an accelerated test for multiple stress sources with an eye towards life prediction
- Determine a life estimate from an accelerated test to failure such as HALT and FMVT using several different methods
- Understand when each method for life prediction can be used
- Program Acceleration
- Recognize the importance of accelerating a whole program and not just an individual test
- Hybrid Test Methods
- Combine two or more tests based on the strengths and weaknesses of the tests
- Synthesis
