ASTM F2133测定钢结构的绝缘船舱壁和甲板的防火效果的标准试验方法

ASTM F2133 Standard Test Methods for Determining Effects of Large Hydrocarbon Pool Fires on Insulated Marine Bulkheads and Decks, Constructed of Steel
ASTM F2133测定钢结构的绝缘船舱壁和甲板的防火效果的标准试验方法

These test methods are intended to provide a basis for evaluating the time period during which bulkheads and decks 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.
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 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 It is feasible that substantial changes in the fire performance characteristics of the assembly will result from any variation from the construction or conditions (that is, size, method of assembly, and materials) that are tested.
The structural assemblies that will be evaluated in accordance with these test methods will be located on a ship.

1. Scope
1.1 These test methods described in this fire-test response standard are used for determining the fire-test response of insulated marine steel bulkheads and decks. The insulation is either homogeneous or composite construction.
1.2 It is the intent that tests conducted in accordance with these test methods will indicate whether bulkheads and decks will continue to perform their intended function during the period of fire exposure. These test methods shall not be construed as implying suitability for use after fire exposure.
1.3 These test methods prescribe a standard fire exposure for comparing the relative performance of different bulkhead and deck 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 Limitations - These test methods do not provide the following:
1.4.1 Full information on the performance of assemblies constructed with components or of dimensions other than those tested.
1.4.2 An evaluation of the degree to which the assembly contributes to the fire hazard through the generation of smoke, toxic gases, or other products of combustion.
1.4.3 Measurement of flame spread over the surface of the test assembly.
1.4.4 The erosive effect that the velocities or turbulence, or both, generated in large pool fires has on some fire protection materials.
1.4.5 Full information on the performance of assemblies at times less than 5 min because the rise time called out in Section is longer than that of a real fire.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for approximate information only.
1.6 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions.
1.7 This test method is based on the fire exposure as defined in Test Methods E 1529 (issued by the Committee on Fire Standards, E05).
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
