Trust me, it is horrible trying to write standards, often there's no right answer between the precise and the practical. You could say "to a pull force of XXN" and then the response would be "what, I need to attach a force meter to every connection?"  Not to say that what you've posted is ideal, but the challenge is to think of a practical better way of putting it...

A common solution is to make it "sufficiently tight and secure", which is actually no better, just begs the question "sufficient for what?"

My guess is that this is more a reminder to people to at least think about it...
