In qualification testing for non-threaded studs, how many specimens must pass?

Explanation:
In qualification testing for non-threaded studs, you’re proving that the studs and the welding method will meet the required performance under the specified tests. Each specimen is checked against the acceptance criteria (strength, ductility, absence of cracks, etc.). The standard sets a fixed target: ten specimens must pass. This provides a reliable benchmark for reliability while tolerating normal variability in materials and workmanship. If fewer than ten pass, the qualification isn’t met and the procedure or materials need to be reassessed.
