in all your links to the national research council Canada. I don't find any reference to your clips only to resilient channel as well as how when installed correctly how well it does.
interestingly one of our engineers pointed out to me under the warrany information for some of your clips it said
NO EXPRESS OR IMPLIED WARRANTIES

merchantable goods are goods fit for the ordinary purposes for which they are to be used
so they won't even say that their own goods will perform as they should even if installed correctly.
I also would like to know where you get your so called failure rating for resilient channel. for that was a big laugh at lunch with the architecte and the engineer on the job that we are currently working.
