CASfire developed fire resistance testing scheme for I-Joist flooring\/ceiling assembly <\/span><\/strong><\/p>\n By testing and evaluating the fire performance according to the national standards and regulations to meet the relevant requirement, and improving the fire resistance, we can minimize the fire risk and reduce the fire damage to people and property.\u00a0<\/span><\/p>\n Fire resistance is the endurance to fire of building material and structure (wall elements, flooring\/ceiling assembly, and fire doors, etc.). Fire resistance can be measured by the time when building materials and structure and construction element can maintain their integrity and insulation under specific fire condition. Such as 30 minutes, 60 minutes, 90 minutes or 120 minutes for fire resistance.\u00a0<\/span><\/p>\n In European and American countries, solid wood joist and I-joist have been widely used in housing construction. And the fire resistance performance has been paid more attention in flooring\/ceiling assemblies with solid wood joist and I-joist.<\/span><\/p>\n In UK, according to the British Building Regulation Fire Safety requirements, the flooring\/ceiling system with solid wood joist or I-joist, including all accessories, such as fire downlight, gypsum board, sound system, shall be tested and evaluated for fire resistance performance in accordance with BS 476-21 and meet the requirements.<\/span><\/p>\n Fire rated downlight is very popular in UK and Europe. And China is the largest export country of fire-rated LED downlight, however, the testing and evaluation of fire resistance performance of LED fire-rated downlight cannot be effectively solved in China due to the complexity of fire resistance test and installation of ceiling system.<\/span><\/p>\n Based on this, CASfire studied The building regulation fire safety and other relevant standard of British and Europe, and made a large number of fire resistance tests and technical survey on flooring\/ceiling system. In 2012, CASfire develop the fire resistance test scheme of solid wood joist ceiling with fire-rated downlights in China. The scheme has been widely supported and recognized by the manufacturers and traders of downlights, including Vertex, Rayven lighting, Leedarson, Hailai lighting, LG lighting, JCC lighting, allled group,\u00a0Philips\u2026<\/span><\/p>\n In the begining of 2020, through 8 years of practical application and technical experience accumulation, CASfire make further efforts to develop fire resistance testing scheme for I-joist ceiling system according to the requirements and entrustment of customers. The testing scheme has been successfully completed and applied.<\/span><\/p>\n Flooring\/ceiling system with Solid wood joist and I-joist can also be used to test and evaluate the fire resistance performance of the following products:<\/span><\/strong><\/p>\n We hope that the development of fire resistance testing scheme of I-joist ceiling can bring greater help to relevant enterprises, reduce fire hazards and protect our lives and properties.<\/span><\/p>\n We provide the fire resistance test according to the following regulation and standards:<\/span><\/strong><\/p>\n\n
