A building has 15,010 square feet of metal decking at the roof level that receives SFRM. How many thickness tests must be conducted on the deck?

To determine the number of thickness tests required for the spray-applied fire-resistant material (SFRM) on the metal decking, it is important to refer to the relevant building codes and standards, such as the International Building Code (IBC) or the ASTM standards governing fireproofing materials.

Typically, standards for spraying fire-resistant materials establish a testing frequency based on the area that needs to be covered. Generally, for sprayed fireproofing materials, a common approach is to conduct one thickness test for every 1,000 square feet of area covered.

In the case of a building with 15,010 square feet of metal decking, the calculation for the number of required thickness tests would be:

1. Determine the number of tests based on the area:
   • 15,010 square feet ÷ 1,000 square feet/test = 15.01 tests

Since only whole tests can be conducted, you would round up to the next whole number, which would result in 16 thickness tests required.

The answer provided indicates that 16 is the correct choice, reflecting adherence to the established testing requirements intended to ensure that the SFRM has been applied correctly and meets fire protection requirements across the entire designated area.

This ensures the
