I think that's as clear as mud, pure obscurification. Especially if he's done 'hundreds of tests'.
You take as many Afnor designed bars and as many ISO designed bars as you can find and you test them all under both testing standards. Then you crunch the results to see if there's a correlation between Afnor and ISO bars with regards to lowest release force. It's a moderate statistical challenge to find the standard deviation for each regime and pronounce a winner.
Having read the specs I'll settle for my initial presumption.
That could certainly be done and likely has been.
ISO21853 is by no means easy (or easier than AFNOR) to pass,
I think your question was unclear, but you did clarify what you were asking for.
I agree I would like to see more transparency on this. One of the problems with iso standards is getting ahold of them.
It is not clear on how they arrived at that number. Presumably some testing rationale.
Decay Obviously has a test bench it would be nice to see a video and results of running a quick release through the tests.
sets the standard for maximum release force (equal to or less than 170N) and opening time (equal to or less than 2 seconds) of quick-release systems under different standardized conditions like
water with and without sand
dry and clean conditions
cold and wet conditions
So about 20 Newton’s or roughly 2 kg difference but I’m not sure of the load,
