9.23.16.2.(1)


Objective	OS3 Safety in Use
Attribution	[F20,F22-OS3.1] Applies to floors and elements that support floors.
Application	Application 1: Wall sheathing in exterior walls, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.], where walls are not: braced, finished on the interior with plaster, gypsum board, plywood, hardboard, insulating fibreboard, particleboard, OSB, waferboard or tile according toSection 9.29., or clad in panel-type cladding.

Intent	Intent 1: To limit the probability of wall sheathing of inadequate thickness or inappropriate specifications or rating, which could lead to: an inadequate fastening base for cladding, inadequate support for required cladding and elements of an environmental separator, or an inability to resist expected lateral or gravity loads, where sheathing provides the required resistance to racking and buckling. This is to limit the probability of: falling cladding, the deformation or displacement of cladding, or the excessive deflection of the wall. For floors and elements supporting floors, this is to limit the probability of: compromised structural integrity, or the displacement or failure of required environmental separation elements, which could lead to deterioration. This is to limit the probability of excessive deflection or vibration, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
