It could be debated that any trim control that can result in sudden manual deflection with catastrophic effects would not be in compliance with CS23.677 (a) Proper precautions must be taken to prevent inadvertent, improper, or abrupt trim tab operation.
The certification criteria to be met following electric trim runaway is expanded upon in CS 23 Book 2, AMC, Flight Test Guide. Chapter 3 No 139. Does this provide the information you are looking for?
Re BCAR Section K, it is stretching my memory somewhat but there were a number of amendments published as " Blue Papers" by the CAA which I do not believe were consolidated into the main body of Section K. I do recall that there was information published by CAA on this subject as checking compliance for trim disconnect was usually part of the process for issue C of A on imported aircraft.
