Attribution
[F20,F22-OS1.2] Applies to assemblies required to provide fire resistance.
Application
Application 1:

Intent
Intent 1: 
To limit the probability of an inadequate diameter, thickness or crown length, or incorrect orientation, of staples, which could lead to inadequate capacity, rigidity or pull-through resistance, which could lead to an inability to resist expected lateral, gravity or wind-uplift loads.
Where assemblies are required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.
