Standar pengujian apa yang berlaku untuk plafon gantung tahan api?

Suspended ceiling systems must undergo full-scale fire tests to certify their resistance to flame, heat, and smoke. In North America, ASTM E119 (Standard Test Methods for Fire Tests of Building Construction) and UL 263 are the primary benchmarks. These tests expose assemblies to a controlled fire curve, measuring structural integrity, insulation, and hose-stream impact performance. European installations reference EN 1364-2 (Fire resistance tests for non-loadbearing elements) and EN 13501-2 classifications, which define integrity (E) and insulation (I) criteria under standardized temperature regimes. ISO 834 provides an international fire-resistance curve for consistency across global markets. Test reports specify time ratings (e.g., 60 min, 120 min) and detail component contributions—aluminum panel thickness, insulation depth, joint treatments, and suspension link performance. Only assemblies tested as complete systems—including panels, grid, insulation, and seals—carry a certified rating; mixing components from different reports risks non-compliance.
