Short answer
ASTM E1155 requires FF/FL measurements within 72 hours after the slab is finished, before shoring is removed on elevated slabs. If you miss that window, the numbers can't be used for acceptance. Book the tester before the pour, not after.
Why it matters for warehouses
Distribution and warehouse slabs along the Loop 202, Loop 303 and I-10 corridors often have FF/FL specs tied to forklift and racking performance. If you test late or don't test at all, you can't defend the slab if the owner disputes it.
What you get
Overall FF/FL numbers and local section values, with a report you can hand the owner.
