Standard Test Methods for Determining Effects of Large Hydrocarbon Pool Fires on Structural Members and Assemblies
SIGNIFICANCE AND USE
5.1 These test methods are intended to provide a basis for evaluating the time period during which a beam, girder, column, or similar structural assembly, or a nonbearing wall, will continue to perform its intended function when subjected to a controlled, standardized fire exposure.
5.1.1 In particular, the selected standard exposure condition simulates the condition of total continuous engulfment of a member or assembly in the luminous flame (fire plume) area of a large free-burning-fluid-hydrocarbon pool fire. The standard fire exposure is basically defined in terms of the total flux incident on the test specimen together with appropriate temperature conditions. Quantitative measurements of the thermal exposure (total heat flux) are required during both furnace calibration and actual testing.
5.1.2 It is recognized that the thermodynamic properties of free-burning, hydrocarbon fluid pool fires have not been completely characterized and are variable depending on the size of the fire, the fuel, environmental factors (such as wind conditions), the physical relationship of the structural member to the exposing fire, and other factors. As a result, the exposure specified in these test methods is not necessarily representative of all the conditions that exist in large hydrocarbon pool fires. The specified standard exposure is based upon the best available information and testing technology. It provides a basis for comparing the relative performance of different assemblies under controlled conditions.
5.1.3 Any variation to construction or conditions (that is, size, method of assembly, and materials) from that of the tested assembly is capable of substantially changing the performance characteristics of the assembly.
5.2 Separate procedures are specified for testing column specimens with and without an applied superimposed load.
5.2.1 The procedures for testing loaded columns stipulate that the load shall be applied axially. The applied load is to be the m...
SCOPE
1.1 The test methods described in this fire-test-response standard are used for determining the fire-test response of columns, girders, beams or similar structural members, and fire-containment walls, of either homogeneous or composite construction, that are employed in HPI or other facilities subject to large hydrocarbon pool fires.
1.2 It is the intent that tests conducted in accordance with these test methods will indicate whether structural members of assemblies, or fire-containment wall assemblies, will continue to perform their intended function during the period of fire exposure. These tests shall not be construed as having determined suitability for use after fire exposure.
1.3 These test methods prescribe a standard fire exposure for comparing the relative performance of different structural and fire-containment wall assemblies under controlled laboratory conditions. The application of these test results to predict the performance of actual assemblies when exposed to large pool fires requires a careful engineering evaluation.
1.4 These test methods provide for quantitative heat flux measurements during both the control calibration and the actual test. These heat flux measurements are being made to support the development of design fires and the use of fire safety engineering models to predict thermal exposure and material performance in a wide range of fire scenarios.
1.5 These test methods are useful for testing other items such as piping, electrical circuits in conduit, floors or decks, and cable trays. Testing of these types of items requires development of appropriate specimen details and end-point or failure criteria. Such failure criteria and test specimen descriptions are not provided in these test methods.

INTRODUCTION
The performance of structural members and assemblies exposed to fire conditions resulting from
large, free-burning (that is, outdoors), fluid-hydrocarbon-fueled pool fires is of concern in the design
of hydrocarbon processing industry (HPI) facilities and other facilities subject to these types of fires.
In recognition of this unique fire protection problem, it is generally required that critical structural
members and assemblies be of fire-resistant construction.
Historically, such requirements have been based upon tests conducted in accordance with Test
Methods E119, the only available standardized test for fire resistant construction. However, the
exposure specified in Test Methods E119 does not adequately characterize large hydrocarbon pool
fires.Test Methods E119 is used for representation of building fires where the primary fuel is solid in
nature, and in which there are significant constraints on the movement of air to the fire, and the
combustion products away from the fire (that is, through doors, windows). In contrast, neither
condition is typical of large hydrocarbon pool fires (see Appendix X1 on Commentary).
One of the most distinguishing features of the pool fire is the rapid development of high
temperatures and heat fluxes that can subject exposed structural members and assemblies to a thermal
shock much greater than that associated with Test Methods E119.As a result, it is important that fire
resistance requirements for HPI assemblies of all types of materials be evaluated and specified in
accordancewithastandardizedtestthatismorerepresentativeoftheanticipatedfireconditions.Such
