Abstract

Andre and Fred discussing the use of parts count prediction by safety standards.

Key Points

Join Andre and Fred as they discuss the misguided recommendations to use parts count predictions in recent updates to safety standards.

Safety standards requiring the calculation of failure rates, often based on constant failure rates Parts counts methods is not accurate to predict future reliability performance Parts count prediction is not the only way to create a prediction. Instead, use your own field data with rigorous failure analysis or physics of failure modeling.

Topics include:

• European safety standards requiring reliability predictions
• The safety risk posed by using parts count predictions
• What you can do instead to improve your predictions and improve product/system safety

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.
