Intent 1:
To limit the probability:
- of inadequate rigidity of underlay panels, or
- that the performance of underlay will fall significantly
below expectations.
This is to limit the probability that
the underlay will be unable to bridge any irregularities in the subfloor
and will telegraph them to the finished flooring, which could lead
to the displacement or cracking of finished flooring.
This is to limit the probability of:
- rough or uneven finished floor surfaces, which could
lead to persons tripping or falling, or
- where finished flooring is required to provide water
resistance, the ingress of water into the subfloor, which could lead
to compromised physical integrity of the supporting structure, which
could lead to uneven finished floor surfaces, which could lead to
persons tripping or falling.
This is to limit the probability of harm to persons.
