When measuring tube steel SFRM thickness, how many measurements can be less than the specified thickness?

Consistent protection relies on every spot meeting or exceeding the specified thickness. When you verify tube steel SFRM thickness, there must be no locations thinner than what is specified, because any under-thickness can create a gap in fire resistance and weaken protection at that spot. Therefore, the acceptable outcome is that none of the measurements are below the specified thickness. Measurements that are at or above the target are fine, but any measurement below the target indicates non-conformance and would require remediation.
