Shaft Average Life according to Codes/Standards

[Jugaado Engineer]

Hello Everyone,

I hope you are doing well. I am currently doing RCA regarding a shaft failure which was continuously in use for the past 10 years without any proper inspection maintenance plans followed regarding it. The last proper maintenance plan regarding shaft inspection was carried out in 2014 and in 2019 it was supposed to be inspected again but the plan was not followed. Now in 2024, this shaft broke resulting in a incident in our company. I was just wondering what is the normal service life of a shaft especially for a motor shaft. If anybody knows about any resources telling about the average service life kindly share those resources and your thoughts on it as well. Moreover if anybody knows about any ASME/API codes that specifically tell us about the average service life of a shaft?

I would really appreciate it if you guys can help me in this issue.
