Sentence 9.29.10.1.(2)

Intent 1:

To limit the probability of 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 deformation or detachment of interior finishes, which could lead to:

• where the substrate is required to protect foamed plastics, a loss of fire protection, or
• where the substrate is required to contribute to the required fire resistance of assemblies, a loss of fire resistance.

This is to limit the probability of the growth and spread of fire, which could lead to harm to persons.
