Hi.
I have a question.
Generally, we use environment conversion factors (mil-hdk-338B) for electrical/electronic equipments. But, in case of NPRD, it is unclear whether these factors are applied for reliability prediction or not.
I saw a thread on this forum. The thread are recommended that these factors could be applied for electrical/electronic equipments. And for mechanical equipments without electonic/electrical componenets, it was not recommeded.
And recently I have read the RIAC-MASTER book. At that book (chapter 5.3.3), any content about using environment conversion factors is not included. The book only shows the qualitative impact between envrionment and quality level.
Thus, I would like to be clear wheter we use environment conversion factors in using NPRD or not .
