How many SFRM thickness tests are required underneath metal decking that is 6,500 sf?

Thickness testing frequency for sprayed fireproofing is determined by area, using one thickness test for every 1,000 square feet (or fraction thereof). For 6,500 square feet, 6,500 divided by 1,000 equals 6.5, and since any fraction requires an additional test, you round up to seven tests. Therefore, seven thickness tests are required underneath the metal decking.
