Random Testing for Anchor Capacity
(OP)
Is there an Acceptance Quality Level, in percent, prescribed for mechanical or grouted anchors?
Thanks

RE: Random Testing for Anchor Capacity
I was hoping to find a statistical basis to reduce the number of tests with the same or better level of confidence and thus wish to use Acceptance Quality Level used in Six Sigma.
To me, 10% infers that they do not have alot of confidence with the installation process.
The anchors I need to test are not Hilti and thus I am looking for a code reference for guidance.

I looked at this document and it states the minimum sample size of 5 so it doesn't really help relate as a function of the total. I don't have ACI 355.
I notice that NYSDOT specifies that all installed anchors for my situation (for a bridge railing system) must be tested, whereas Minnesota state once used to do this in-house testing with a minimum of three.
So between Hilti, NY and Min states it appears all over the place.
