Subject: Environmental Conversion Factors
Message:
I am looking at the RAC Reliability Toolkit: Commercial Practices Edition, page 176. I want to convert a system series MTBF from a particular temperature and environment to a different temperature and a different environment. Do I apply both the environmental conversion factor from the environmental table AND the temperature conversion factor from the temperature table? I was previously told to use ONLY the environmental factor, which does not seem reasonable.
