ObjectiveOS1 Fire Safety
Attribution
[F20,F22,F80-OS1.2] Applies to assemblies required to provide fire resistance.
Application

Intent
Intent 1: 
To limit the probability that the performance of steel studs and runners, with respect to material, profile, dimensions and tolerances, cutouts, corrosion protection and screw-holding ability, will fall significantly below expectations, which could lead to an inability to resist expected lateral and gravity loads.
For assemblies that are required to provide fire resistance, this is to limit the probability of excessive movement, deformation or failure under expected loads, which could lead to compromised fire resistance of the assemblies, which could lead to harm to persons.
