All of Bondor's insulated panels are designed for building resistance, embracing key performance areas such as fire resistance to ensure their ability for use across a large range of applications and geographic areas. Bondor's panels are constructed with BlueScope steel, and either a PIR, EPS-FR, MW or PUR core. These panels have undergone vigorous testing and have achieved various (FIRE ACCREDITATION?) as listed below. Material Group Numbers (Specification C1.10 Fire Hazard Properties ) SPECFICATION C1.10 FIRE HAZARD PROPERTIES, Wall and Ceiling Linings provides a required Group Number for wall & ceiling lining materials, based on the Class of building, the location within the building, and whether or not the building is sprinkler protected or not. Note: For buildings not protected with a sprinkler system, a smoke growth rate of not more than 100 is required. In this test a 3.6 by 2.4 m room is built and exposed to a gas flame with 100kW of energy for 10 minutes, and then 300kW of energy for 10 minutes ratings are defined as: Group 1 Material The test specimen lasts the full 20 minutes without flashing over Group 2 Material The test specimen flashes over in more than 10 minutes and less than 20 minutes Group 3 Material The test specimen flashes over in more than 2 minutes and less than 10 minutes Group 4 Material The test specimen flashes over in less than 2 minutes
