3、a to 1.25 Pa.INTRODUCTIONThe performance of structural members and assemblies exposed to fire conditions resulting fromlarge, free-burning (that is, outdoors), fluid-hydrocarbon-fueled pool fires is of concern in the designof hydrocarbon processing industry (HPI) facilities and other facilities subj

5、nly available standardized test for fire resistant construction. However, theexposure specified in Test Methods E119 does not adequately characterize large hydrocarbon poolfires. Test Methods E119 is used for representation of building fires where the primary fuel is solid innature, and in which the

In contrast, neithercondition is typical of large hydrocarbon pool fires (see Appendix X1 on Commentary).One of the most distinguishing features of the
7、pool fire is the rapid development of hightemperatures and heat fluxes that can subject exposed structural members and assemblies to a thermalshock much greater than that associated with Test Methods E119. As a result, it is important that fireresistance requirements for HPI assemblies of all types
8、of materials be evaluated and specified inaccordance with a standardized test that is more representative of the anticipated fire conditions. Sucha standard is found in the test methods herein.1. Scope*1.1 The test methods described in this fire-test-responsestandard are used for determining the fir

10、st methods will indicate whether structural members ofassemblies, or fire-containment wall assemblies, will continueto perform their intended function during the period of fireexposure. These tests shall not be construed as having deter-mined suitability for use after fire exposure.1.3 These test me

These heat flux measurements are being made tosupport the development of design fires and the use of firesafety engineering models to p
