For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause.
authority having jurisdiction (AHJ): An organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation, or a procedure.
emergency isolation valve (EIV): Is intended to provide a means of shutting off flow of a fuel with either manual or remote power operation.fire rated cable system (FRCS): Generally described in this standard, each cable manufacturer should have.
FRCS for its fire rated cables that complies with IEEE Std 1717TM or functionally equivalent fire test.fire rated splice: A cable splicing method that will maintain ectrical integrity during hydrocarbon pool fire (HPF).
fire resistance rating: The number of minutes in a standardized test without reaching a failure criterion. (In this publication IEEE Std 1717TM or functionally equivalent test conditions are presumed for pool fires unless otherwise stated.)
fireproofing: Is a systematic process, including design, material seleection, and the application of materials,that provides a degree of fire resistance for protected substrates and assemblies. hydrocarbon pool fire (HPF): A turbulent difusion flame burming above a horizontal pool of vaporizing hy- drocarbon fuel under conditions where the fuel vapor or gas has zero or very lttle initial momentum. lubricant: Any material applied on the cable or into a conduit to reduce friction, and hence tension, during cable pulling operations. motor operated valve (MOV): An ecrically actuated valve. cable sample: The individual length of cable or cable bundle to be tested.
All cable tray materials, support, acessories, wire ties, clamps, fasteners, straps, couplings, cleats, covers;
separators should be made out of steel or other materials as was tested in the HPF.Cable should be installed in the same manner as was tested in the HPF. For example, if the cable has only been tested horizontally, the cable should not be installed vertically. Consult the cable manufacturer if vertical drops or horizontal bends will be installed in the HPF areas.
The cable tray type and construction details that were used in the HPF test should be the minimum used in the installation. Key attributes of the cable tray are rung spacing and strength rating. It is generally accepted that higher load rating of the cable tray will perform equally in the HPF test. It should not be assumed that a cable tray with coating can be substituted for a cable tray that was not coated during the HPF fire test. Rung spacing is important; cable should be installed on the same or reduced rung spacing as tested in the cable HPF fire test.Rungs should not be brazed.
Cable tray supports are an important part of the fire rated cable system installation. The maximum distance between supports is critical under fire condition and should be the same distance or less as was tested in the cable HPF test. The distance between supports may be increased by the AHJ if acceptable cable tray sag (deflection) test data at the desired support distance and loading under HPF conditions is available. The deflection at longer support distances should be less than or equal to what was tested in the HPF test.
Fire rated cables should be installed in a dedicated tray. When approved by the AHJ, it should be permissable for fire rated cables to share the tray with non fire rated cables when separated by a steel barrier. The barrier is required regardless of the type of cables such as tray cable or armored. The barrier will keep other cable materials physically separated from the fire rated cables.
When fire rated cables are below non-fire rated cable or other combustible materials or flling debris, tray COVer should be used to protect the fire rated cables.
Fire rated cables should be installed in a single layer, unless tested in other configurations in the HPF test.IEEE 1810 pdf download.
