BS 8619:2020 pdf free.Determination of the resistance to hydrocarbon pool fires of fire protection materials and systems for pressure vessels – Test method.
BS 8619 This British Standard specifies a test method for the determination of the resistance to hydrocarbon pool fires of pressure vessels with a fire protection system when subjected to standard fire exposure conditions. It does not apply to vessels cooled by water deluge or water monitor. The pressure vessel can be classified based on its performance during the test. The design of the pressure vessel is not covered in this British Standard.The following documents are referred to in the text in such a way that some or all of their content constitutes provisions of this document. For dated references, only the edition cited applies.) For undated references, the latest edition of the referenced document (including any amendments) applies.BS EN 12542, LPG equipment and accessories一Static welded steel cylindrical tanks, serially produced for the storage of Liquefied Petroleum Gas (LPG) having a volume not greater than 13 m3一Design and manufacture PD 5500, Specification for unfired fusion welded pressure vessels [N1] IEC Electropedia (https://www.electropedia.org)[N2] ISO Online Browsing Platform (https://www.iso.org/obp/ui) protection afforded to the vessel to reduce the rate of heat transfer from the fire to the vessel throughout the period of exposure to fire, including any protection materials together with any encasement and supporting system and any specified primer and top coat if applicable NOTE 1 For example, an encasement might be a jacket.NOTE2 For example, a supporting system might be mesh reinforcement or a framing system. NOTE3 A fire protection system is also referred to as a “thermal protection system.” This method provides an indication of how vessels protected with fire protection materials, or systems, perform when exposed to pool fires on solid surfaces. It simulates the thermal loads to a vessel engulfed in a large pool fire through the use of burners to create a flame capable of engulfing a vessel. The simulated liquid hydrocarbon pool fire achieves a heat flux to a cool surface of 90 kW.m~2 to 120 kW.m-2.To ensure that suitable test conditions are achieved and maintained, it describes calibration tests to be performed prior to fire testing, sets permitted tolerances from the calibrated set-up, and delimits environmental conditions.
