on wood furring or framing, in buildings to which
Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application

| Intent | Intent 1: To limit the probability of an inadequate penetration of
fasteners, which could lead to an inability to resist expected impact, gravity
or lateral loads. Where interior finishes support or serve
as required environmental separation elements, this is to limit the probability
of the deformation or detachment of interior finishes, which could lead to
the failure of required environmental separation elements, which could lead
to:
This is to limit the probability of:
This is to limit the probability of:
This is to limit the probability of harm to persons.
Intent 2: To exempt assemblies from the application of this Sentence,
where fire tests have proven that shorter nails or screws will be adequate
for the required fire-resistance rating. |
