Application
Application 1:

Intent
Intent 1: 
To limit the probability of inadequate withdrawal resistance, which could lead to an inability to resist withdrawal forces imposed by the shrinkage of floor framing, which could lead to—where resilient flooring is installed to provide required moisture resistance [see Article 9.30.1.2.]—nail popping, which could lead to compromised integrity of the moisture protection, which could lead to exposure of the subfloor to water.
This is to limit the probability of deterioration, which could lead to compromised integrity of the floor system, which could lead to harm to persons.
