Table 6 Method of assessment Assessment method Level of complexity Basic assessment NCC procedure for determining fireFire hazard properties in accordance with S7C4(2) performance Type of assessment Qualitative and comparative, Qualitive, comparative 6.3Tested system In test RTF252619 R1.0, the specimen consisted of DeltaCool smooth insulated panels with a mineral wool core, supplied by Delta Panel. Each panel measured 2400 mm high1219 mm overall width (1200 mm effective face)100 mm thick, with a 99 mm mineral wool core sandwiched between two 0.65 mm painted steel skins. The panels featured tongue-and-groove vertical joints for interlocking, sealed with FR sealant and secured using 4 mm stainless steel rivets at 300 mm centres. This specimen achieved group number 1 and recorded SMOGRA RC(in m2/s21000) of 1.5.6.4Variation in thickness It is proposed to assess a 75 mm thick DeltaCool panel. As discussed above, a 100 mm thick DeltaCool panel was previously tested under report RTF252619 R1.0. During the test, the fire remained localised around the burner. Under a 100 kW exposure, the total heat release rate (HRR) was close to the burner output, and the same was observed when the burner exposure was increased to 300 kW. This indicates minimum contribution to the heat release rate from the tested specimen. Reducing the panel thickness to 75 mm is expected to lower the overall fuel load within the room. This reduction should decrease the potential heat release rate and deliver an equal or improved group number performance. Based on the above observations and considering the safety margin demonstrated in the test, it is concluded that the proposed 75 mm thick DeltaCool panel is capable of achieving group number 1 in accordance with AS 5637.1:2015. 6.5Variation in profile In test RTF252619 R1.0, the tested specimen consisted of smooth profile of the steel skin. It is proposed to assess Ribbed, MicroRibbed, 5V and Single V profiles. The variation in steel skin profiles is not expected to Page 11 of 21 Copyright 2025 Jensen Hughes, Inc.All Rights Reserved.
