To limit the probability that the performance of the installed
masonry, with respect to integrity and protection against precipitation ingress,
will fall significantly below expectations, which could lead to precipitation
ingress into or through assemblies.
This is to limit the
- the inadequate structural strength and integrity of the installation,
which could lead to falling masonry components, or
- deterioration, which could lead to compromised structural integrity
of the separators or of elements supported or protected by the separators.
This is to limit the probability of structural failure, which could
lead to harm to persons.
