Acceptability Criteria 
It shall be demonstrated comparatively that the DeltaDualCore™ system (when attached to a Class 1 
building within 900 mm of the site boundary) does not increase the risk of fire spread between Class 1 to 
Class 9 buildings when compared to the DtS base case.

Design Fires 
Three fire scenarios are to be considered; one within the Class 1 building, one within or below the 
Class 10a structure and one on the neighbouring allotment. The three design fires are described in 
Sections 4.7.1.1 to 4.7.1.3 below. 
4.7.1.1 
Design Fire 1: Fire Within or Below the Class 10a Structure 
In the case of a Class 10a structure intended to be used for a patio or awning application, fire load is likely 
to be limited as it would not be fully protected from the weather. However, the patio or awning is able to 
house a wide range of fire loads which may include a combination combustible goods such as external 
furnishings, storage of household goods, a laundry rack, gardening supplies and the like.  
To quantify a worst credible design fire the following fire loads are considered: 
• 
Upholstered Sofas – 500 kW to 2900 kW as shown in Figure 4-4.
