In reply to David Coley:
Yes it used to 12kN in the standard but below 10kN is better and the new standard, which is the current maximum arresting force. It is at this point force limiting to protect the user, to some degree, and the anchor.
Equally there is a threshold below which you don't want it to slip... Otherwise it would slip with a normal in use static load. The sweet spot is between 5 and 10kN... I have seen the 5kN cited but can't find that now and not really sure why for an adjustable lanyard like the connect why there isn't a minimum it must sustain before it slips.
