Intent 1:
To limit the probability that the performance of
steel, with respect to strength or stiffness, will fall significantly
below expectations, which could lead to an inability to resist expected
gravity loads, which could lead to excessive deflection.
For environmental separators or construction that supports
environmental separators, this is to limit the probability of the
displacement or failure of required environmental separation elements,
which could lead to:
- condensation,
- precipitation ingress,
- excessive heat transfer,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- inadequate control of temperatures of interior spaces,
drafts, relative humidity or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to further compromised
integrity of environmental separators.
This is to limit the probability of:
- negative effects on the air quality of indoor spaces,
- the inadequate thermal comfort of persons, and
- contact with moisture.
This is to limit the probability of harm to persons.
