Objective | OS2 Structural Safety |
Attribution | |
Application | Application 1: Underlay for resilient flooring, parquet flooring,
ceramic tile, felted-synthetic-fibre floor coverings and carpeting laid over
lumber subflooring, in buildings to which Part
9 applies [see Sentence 1.3.3.3.(1) of Division A for application of
Part 9]. |

Intent | Intent 1: To limit the probability of excessive irregularities on
the surface of the substrate on which the finished flooring is installed,
which could lead to the displacement or cracking of finished flooring.
Where finished flooring is required to provide water resistance,
this is to limit the probability of the ingress of water into the subfloor,
which could lead to compromised structural integrity of the supporting structure,
which could lead to an inability to resist expected gravity loads, which could
lead to structural collapse, which could lead to harm to persons.
