Many new tech have limited stability for one reason. In addition, the bathtub failure curve, you need to root out early failure. (believe me, burn in will root out something design over looked or unit operated on the cutting edge spec) . As for exemption, you need to find pm who is willing to put his head on line. ‎https://www.tjgreenllc.com/2016/09/20/new-release-of-mil-std-883-visual-inspection-criteria/

Subject: [TN] MIL-STD-833 Method 1015

Can anyone shed some light on the rationale behind the Post Burn-In 96 hr window defined in MIL-STD-833 Method 1015? I am trying to understand this, to determine the risk of excluding this requirement from the Burn-In process in a high reliability IPC Class 3 application.
