Certification & Testing
Combustibility:
K-Roc® Roofliner Panel is a bonded laminated material. It achieves the following fire test results, as required by clause C2D10 (6)(g) of the National Construction Code (NCC). Therefore, it can be used wherever a non-combustible material is required by the NCC.
Mineral wool core is not deemed combustible when tested to AS 1530.1 1994 (R2016).
Panel steel skin (uncoated) is not deemed combustible when tested to AS 1530.1 1994 (R2016).
Test: Ignitability - Ignitability index: 0 as per AS/NZS: 1530.3: 1999
Test: Flame Spread - Spread of flame index: 0 as per AS/NZS: 1530.3: 1999
Test: Heat Release - Heat evolved index: 0 as per AS/NZS: 1530.3: 1999
Test: Smoke Release - Smoke developed index: ≤3 as per AS/NZS: 1530.3: 1999
There are two factory-applied adhesive layers applied during the manufacture of the product. Each adhesive layer does not exceed 1 mm in thickness and the total thickness of the adhesive layers does not exceed 2 mm in thickness. K-Roc®Roofliner Panel meets the requirements of C2D15 ‘Fixing of Bonded Laminated Materials’ when located externally.
Test: NCC group number in accordance with AS 5637.1: 2015 using AS ISO 9705 2003 (R2016) is Group 1.
Smoke growth rate index (SMOGRARC) (m2/S2 x 1000) using AS ISO 9705 2003 (R2016) is <100.
