Flexible mat with endothermic technology that, when exposed to high temperatures or flame, releases chemically bound water to slow heat transfer and help protect critical electrical and structural components from fire. Non-flame supporting, low-smoke evolution and fast installation make this an excellent fire barrier for structural steel and electrical circuitry. Meets the following ASTM (UL) and NBN/ISO Standard Test Requirements: ASTM E 84 (UL 723) Surface Burning Characteristics of Building Materials ASTM E 119 (UL 263) Fire Tests of Building Construction and Materials ASTM E 1529 (UL 1709) Determining Effects of Large Hydrocarbon Pool Fires on Structural Members and Assemblies ASTM E 1725 Fire Tests of Fire-Resistive Barrier Systems for Electrical System Components NBN 713-20/ISO TC 92 Simulated Jet-Fire Test
