1、Designation:F224711Standard Test Method forMetal Doors Used in Blast Resistant Applications(Equivalent Static Load Method)1This standard is issued under the fixed designation F2247;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the structural performance ofmetal doors and frames and their restraining hardware(such asl
3、atches and hinges)used as a blast resistant barrier.Thismethod involves applying an equivalent static pressure basedon the characteristics of the specified blast pressure andstructural properties of the door panel design.1.2 The static tests are valid for the unit size tested or forsmaller units of
4、analogous construction.Extrapolation of testresults for units larger than the test specimen are not permitted.1.3 This standard test method is not applicable to testswhere the forces are created by explosive charges,forced airfrom a shock tube apparatus,or any other method used togenerate a dynamic
5、load.1.4 The proper use of this method requires knowledge of theprinciples of pressure,deflection,and when applicable,straingauge measurement.1.5 Using this method,specimens may be tested to deter-mine ultimate static capacity or tested to specific static testloads.1.5.1 Procedure A shall be used wh
6、en a load-deflectioncurve is not required and a single load is applied.1.5.2 Procedure B shall be used when a load-deflectioncurve is required and a single or multiple loads are applied.1.6 The values stated in SI units are to be regarded as thestandard.The values provided in parenthesis are for inf
7、orma-tion only.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.R
