b'Supporting Test Data A.1. CSIRO report numbered FSZ 2411 On 18 October 2023, CSIRO conducted a bushfire test in accordance with AS 1530.8.12018 on a 45-degree pitched steel framed roof clad with Delta Panels that measured nominally 2000 mm wide x 1550mm deep that incorporated a 150mm wide x 50mm thick valley gutter located 450mm from the right barge edge of the exposed face. The pitch of the roof systems was 45 degrees. Specimen Detail The roof was fabricated from three 100-mm thick DeltaTrim-TPC panels cut to 1550-mm length, the centre of the roof used a full width panel measuring 1000-mm wide (DeltaTrim-TPC Opp Cut), and two part width panels measuring 400-mm wide (DeltaTrim-TPC LH Cut) and 450-mm wide (DeltaTrim-TPC RH Cut) were used on the left and right hand edges of the roof respectively. The DeltaTrim-TPC panels comprised a thermosetting phenolic composite core (TPC) with a stated density of 38-42 kg/m3. The core was bonded on both sides to 0.6-mm thick roll formed steel skins using two-part polyurethane adhesive, the underside of the panel was flat, and the top steel skin had a Trimdeck profile. The bottom edge of the DeltaTrim-TPC panels were protected with profiled 1.2-mm thick roll formed steel skin DeltaTrim Fascia flashing (TPC-003) fixed with 13g x 25-mm self-drilling steel screws at 200-mm centres , and the exposed roof ribbing edges were covered with Delta TrimEnd Caps (TPC-R015) that were fully sealed with Boss FireSilicone-EMA sealant. The DeltaTrim-TPC panels were fixed to the steel frame using TEK 14 x 175 Hex screws and cyclone clips. All the joints on the underside of the roof were filled with a bead of FireSilicone-EMA sealant. The left and right barge edges of the roof were fitted with x 0.6-mm thick roll formed profiled steel skin DeltaTrim 100-mm side barge trims (TPC-R006 and TPC-006-RH) fixed with TEK 14 x 175 Hex screws at 200-mm centres. The right side of the roof incorporated a 150-mm wide valley gutter located 450-mm from the right barge edge. The valley gutter consisted of a 50-mm thick x 150-mm wide mineral wool core with a stated density of 38-42 kg/m3 covered on the top side with a 30-mm x 50-mm 150-mm wide x 0.6-mm thick roll formed steel skin (TPC-R005) fixed with Tex screws at 200-mm centres and a 230-mm wide x 0.6-mm thick roll formed steel skin Valley gutter flashing (TPC-R010) on the underside fixed with stainless steel rivets at 200-mm centres and the edges covered with FireSilicone-EMA sealant. Located at the ridge of the roof was a x 0.6-mm thick roll formed profiled steel skin ridge cap (TPC-R014) fixed screws. All exposed gaps between the DeltaTrim-TPC panels and the ridge cap and the fibre cement sheeting on the sides were filled with a bead of FireSilicone-EMA sealant. The roof specimen was fitted with a 120-mm wide x 140-mm high standard steel roof gutter. The roof structure was enclosed at the back of the test frame with oriented strand board (OSB) thatincorporated a 100-mm x 100-mm vent opening located at the base of the roof and a 200-mm x 200-mm glass vision panel. Support construction The Delta Panels roof system was fixed to a DeltaTrim TPC test frame (TPC-R011) that measured 2040-mm wide x 880-mm deep x 1590-mm high at the back and 480-mm high at the front, fabricated using 65-mm x 65-mm SHS, 50-mm x 50-mm x 3-mm thick angled base and 1.2-mm BMT Beam cap (200-BEAM) located at the top. The test frame was lined on both sides and the bottom with 6-mm thick fibre cement sheeting (TPC-R009 and TPC-R013) and a 100-mm thick DeltaCool -TPC insulated panel wall at the front.
