It is both block but the manufacturer is insisting on just giving us a test report for the 8" and that "no one" tests 12" block. In my mind there should be a submission/test for both.
On a project that is mostly 12" CMU with some 8" would you think it normal to only submit the ASTM C140 test results for the 8" and not the 12" block? The manufacturer is essentially using an extrapolation argument.
Thank you for your time and consideration.
