APPLICATION:
In
buildings to which Part 9 applies [see
Sentence
1.3.3.3.(1) of Division A for application of
Part 9]:
- glass sidelights greater than 500 mm wide that
could be mistaken for doors,
- glass in storm doors,
- glass in sliding doors within or at entrances to dwelling units and in public areas, and
- entrance doors to dwelling units and in public areas, where the glass area exceeds 0.5 m2 and
extends to less than 900 mm from the bottom of the door [see Sentence
9.6.6.2.(3)].
INTENT:
To limit the probability that the performance of glass in
sidelights and doors, with respect to strength, will fall significantly below
expectations, which could lead to the glass being unable to resist accidental
impact loads from people or objects, which could lead to glass breakage, which
could lead to harm to persons.

which could lead to glass breakage, which could lead to harm to persons.
