![]() The test evaluates the joint system's resistance to heat and, in some instances, to a hose stream, while carrying an applied load if the assembly is load bearing. The intent of these methods is to develop data to assist others in determining the suitability of the joint systems where fire resistance is required.ġ.3 These requirements are intended to evaluate the length of time that the types of joint systems specified in 1.1 will contain a fire during a predetermined test exposure. UL 2079 Standard for Tests for Fire Resistance of Building Joint Systemsġ.1 These tests are applicable to joint systems of various materials and construction that are intended for use in linear openings between adjacent fire resistive structures.ġ.2 The fire endurance ratings for joint systems are intended to register performance during the period of fire exposure and are not intended to be interpreted as having determined the acceptability of the joint systems for use before or after fire exposure. Only products which bear UL's Mark are considered Certified. The Guide Information includes specifics concerning alternate materials and alternate methods of construction. Users of fire resistance assemblies are advised to consult the general Guide Information for each product category and each group of assemblies. When field issues arise, it is recommended the first contact for assistance be the technical service staff provided by the product manufacturer noted for the design. The published information cannot always address every construction nuance encountered in the field. Variations from the published specifications should be considered as not being investigated by UL.ĭesign/System/Construction/Assembly Usage DisclaimerĪuthorities Having Jurisdiction should be consulted in all cases as to the particular requirements covering the installation and use of UL Certified products, equipment, system, devices, and materials.Īuthorities Having Jurisdiction should be consulted before construction.įire resistance assemblies and products are developed by the design submitter and have been investigated by UL for compliance with applicable requirements. These summaries are also published in this Directory. The Report also contains a summary of important features of the rated assembly. Sponsors may provide copies of the complete Test Report upon request. When a test assembly complies with the acceptance criteria, a detailed description of the assembly, its performance in the fire test, and other pertinent details such as specification of materials, certification coverage and alternate assembly details are included in a Report for the test sponsor. The average furnace temperature from which these ratings are derived is 1000☏ at 5 min., 1400☏ at 15 min., 1550☏ at 30 min., 1700☏ at 60 min., 1850☏ at 120 min., 1925☏ at 180 min. It does not store any personal data.This category covers fire-rating certifications based upon the test method and acceptance criteria in ANSI/UL 263 (ASTM E119), "Fire Tests of Building Construction and Materials." The ratings are expressed in hours and are applicable to floor-ceilings, roof-ceilings, beams, columns, walls and partitions.
