24 inch 500 wall, 12 straps(4 bends 8 breaks), the test is not timed, they have someone run your heat on your bead and then you are on your own. You fill and cap with 3/16 70+, They look at the bead and then they leave you to it. Not bad. Great guys to work with, if you have any questions dont be afraid to ask them. Good luck.
