Intent 1:
To limit the probability of inadequate strength
of cementitious material, which could lead to the dislodgement of
tiles or the ingress of water behind tiles, which could lead to compromised
protection for moisture-vulnerable substrates, which could lead to
the deterioration of the substrate, which could lead to studs being
unable to resist expected impact, gravity or lateral loads.
This is to limit the probability of:
- the generation of pollutants, on surfaces or within
assemblies, from biological growth or from materials that become unstable
on wetting, or
- where the substrate serves as a required environmental
separation element, the failure of such elements, which could lead
to:
- condensation,
- precipitation ingress,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures of interior spaces,
- the further 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,
or
- the inadequate thermal comfort of persons.
This is to limit the probability of harm to persons.
