5.4.1.2.(1) | Application | Intent |
OH1 | OS2 | OS1 |
Objective | OS1 Fire Safety |
Attribution | |
Application | Application 1: Air leakage characteristic of materials installed
to provide the principal resistance to air leakage in building components
and assemblies. This applies to building materials,
components, assemblies and their interfaces described in Sentence 5.1.2.1.(1) that
are installed in buildings to which Part 5 applies
[see Sentence 1.3.3.2.(1) of Division A for application of Part 5].
Exceptions:
except as stated in Sentences 5.4.1.1.(3) and 5.4.1.2.(2), which apply where an inadequate control
of air leakage or the installation of materials with an air leakage characteristic
greater than 0.02 L/(s • m2), measured at an air pressure
difference of 75 Pa, will not adversely affect health, safety,
the intended use of the building or the operation
of building services.

Intent | Intent 1: Where required life safety systems are incorporated in environmental
separators, to limit the probability that installed materials will not be
sufficiently airtight, which could lead to an inadequate control of heat loss
due to air mass transfer, which could lead to freezing, which could lead to
compromised operation of temperature-sensitive life safety systems, which
could lead to harm to persons. |
