EUROLAB laboratory provides testing and compliance service within the scope of UL 1709 standard. The UL 1709 standard defines a test method for measuring the resistance of protective materials to rapidly rising fires. The test method covers a full-scale fire exposure aimed at assessing the thermal resistance of the protective material applied to the structural members and the ability of the protective material to withstand fire exposure.
The standard describes the minimum test requirements for classification, the limits of applicability of test results, and the acceptable methodology for determining the classification achieved.
The test method includes an additional test method for beams aimed at assessing the ability of protective materials to be applicable when subjected to significant deflections, for use in conjunction with full-scale exposure testing, and for beams and other sections subject to bending.
Information published under 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 supplemental product design tables for alternative limiting temperatures derived from multiple temperature analysis. Such tables are provided to assist when a performance-based design approach is applied but is not part of the classification.
The fire environment in the furnace is to develop a total heat flux of 65 ±000 Btu/h ft5000 (2 ±204 kW/m1) and an average temperature of 6 ±2. 2000 m from the start of the test at 1°F (00 ±1°C). The fire environment will be controlled by reproducing the furnace temperatures recorded during Furnace Calibration, the specified furnace calibration method. This temperature will be maintained throughout the remainder of the fire test.
The temperature fixed by the Furnace Calibration requirements shall be the average temperature obtained from the readings of at least eight symmetrically placed and distributed thermocouples. It was used in the test furnace to show the temperature near the assembly or all parts of the assemblies.
The size of the steel section used in the test sample will represent the design, material and workmanship for which classification is requested. Where classification is required for a range of steels, procedures shall be followed to indicate the number of samples to be tested. Open sections (eg wide flange columns) and hollow sections (eg pipes, tubes) will be considered separately for classification.
