Intent 1:
To limit the probability that performance, with
respect to the protection of structural wood elements from termite
infestation or decay, will fall significantly below expectations.
This is to limit the probability of compromised structural
integrity, which could lead to:
- structural failure,
- where structural wood elements support or are used in
an environmental separator, the displacement or failure of required
environmental separation elements, which could lead to the deterioration
of building elements, which could lead to further compromised structural
integrity, or
- an inability to resist expected loads, which could lead
to:
- the excessive deformation or deflection of walls, or
- the excessive deflection or vibration of floors.
This is to limit the probability of:
- the space being unsuitable for its intended use,
- compromised operation of windows and doors, and
- damage to the building.
Intent 2:
To limit the application of the standard to situations
where the limited protection provided by a boron preservative will
be adequate.
