i) 
Each lamina, including any core, is non-combustible; and 
ii) 
Each adhesive layer does not exceed 1 mm thickness and the total thickness of the adhesive 
layer does not exceed 2 mm; and 
iii) 
The Spread-of-Flame Index and Smoke-Developed Index of the bonded laminated material 
as a whole does not exceed 0 and 3 respectively. 
 
Equivalence with NCC H3D2(1) is demonstrated in Table 4-1. 
 
Table 4-1. Assessment of equivalence to DtS. 
 
DtS requirements for a bonded 
laminate to be used as a non-
combustible material: 
DeltaFireX Car Port System Roof Panel Bonded 
Laminates (i.e. DeltaTrim-MW and DeltaOrb-MW): 
1 
Each lamina, including any core, is non-
combustible 
The specifications of the DeltaTrim-MW and DeltaOrb-
MW sandwich panel systems are given in Appendix C. 
The laminae comprise: 
• 
steel top skin (0.42 mm G550 AZ150); 
• 
steel bottom skin (0.55 mm G300 Z275); 
• 
Mineral wool core (100 kg/m3) 
The steel top and bottom skins consist of low carbon 
steel which has been tested to AS1530.1 and is not 
deemed combustible (fire test certificate given in 
Section A.2). The surface finish of the top and bottom 
skin is less than 1 mm thick with a Spread-of-Flame 
Index of 0 (refer to applicable AS1530.3 fire test 
certificates given in Sections B.3, B.4, B.5, B.6 and B.7 
and DeltaTrim-MW and DeltaOrb-MW specifications 
given in Sections C.1 and C.2).  
The mineral wool core material has been tested to 
AS1530.1 and is deemed non-combustible (refer to the 
AS1530.1 fire test certificate given in Section A.1). 
On this basis, all laminae are considered non-
combustible in accordance with the DtS provisions.

Each adhesive layer does not exceed 1 
mm thickness and the total thickness of 
the adhesive layer does not exceed 2 
mm 
The DeltaTrim-MW and DeltaOrb-MW bonded laminate 
panels incorporate combustible adhesive layers to bind 
the laminae. Each adhesive layer shall be less than 1 
mm thick. The combined thickness of the two adhesive 
layers shall therefore be less than 2 mm in total.  
3 
The Spread-of-Flame Index and Smoke-
Developed Index of the bonded 
laminated material as a whole does not 
exceed 0 and 3 respectively 
The DeltaTrim-MW and DeltaOrb-MW bonded laminate 
panels have each been tested as a system to AS1530.3 
with fire test certificates given in Sections B.1 and B.2. 
The fire test certificates indicate that the Spread-of-
Flame Index and Smoke-Developed Index for both 
DeltaTrim-MW and DeltaOrb-MW bonded laminate 
panels are: 
Spread-of-Flame Index: 0 ≤ 0 … ACCEPTABLE
