Subject: Realistic Quality Factor for Reliability Prediction of Commercial Components
Hi, I am currently carrying out a reliability prediction for a military equipment that uses commercial components. I'm using Parts Stress Analysis. According to MIL-HDBK 217F, the "Pie Q" for these commercial components is above "1". This may be true more than 10 years ago, when 217F is being written, but is it still true now? Please advise. What is a more realistic "Pie Q" that I should use now? Can it be as low as "1"? Thank you for your help.
