UL 1709 5th Edition, February 24, 2017 UL Standard for Safety Rapid Rise Fire Tests of Protection Materials for Structural Steel
More info
Description / Abstract:
This standard describes a test method for measuring the resistance of protective materials to rapid-temperature-rise fires.
The test method covers a full-scale fire exposure, intended to evaluate the thermal resistance of protective material applied to structural members and the ability of the protective material to withstand the fire exposure.
The standard describes the minimum testing requirements for classification, the limits of applicability of test results and acceptable methodology to determine the classification achieved.
The test method includes a supplementary test method for beams, intended to evaluate the ability of protective materials to perform when subject to significant deflections, for use in conjunction with the full-scale exposure test and applicable for beams and other sections subject to bending. Information published in accordance with this test method may also include product design tables for beams and sections subject to bending derived from the supplementary test method and accompanying methodology.
Information published in accordance with this test method may also include supplementary product design tables for alternate limiting temperatures derived from a multi-temperature analysis. Such tables are provided to aide in conditions where a performance-based-design approach is implemented, but are not part of the classification.
