1、Designation: F2927 12Standard Test Method forDoor Systems Subject to Airblast Loadings1This standard is issued under the fixed designation F2927; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i

2、n 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 identifies the standard procedures thatshall be followed when utilizing either a shock tube or acontrolled open-air explosion

3、to evaluate the blast capacity ofa door system. This test method is designed for all types ofswinging doors, including single and double doors construc-tion. This method is used to test complete door assemblies. Adoor assembly includes the door panel(s), latching hardware,hinges, post mullion (if ap

4、plicable), frame and frame connec-tion to a rigid reaction structure. The door panel(s) may alsocontain one or more integral vision lites (glazing systems). Theglazing system may include, but not be limited to thosefabricated from monolithic glass, laminated glass, plastic,glass-clad plastics, glass

5、/plastic glazing materials, and filmed-backed glass. The results gathered from this method can beused for door installations in non-rigid wall openings. The testmethod may be adapted to horizontal sliding and vertical-liftdoors.1.2 The scaled range or standoff of the charge shall be 1 m(3 ft, 3 in.)

6、 or greater from the specimen in order to reduce oreliminate any punching effect the blast may have on thespecimen. A charge-in-contact blast test is not covered by thismethod.1.3 This test method and the resulting data are valid for thedoor size tested and smaller doors of identical construction.Ac

7、ceptance criteria are divided into five Door ResponseDamage Categories (Categories I, II, III, IV and V). Refer tosection 7.1 and Table 1 for a description of each category.1.4 A door assembly may also contain ancillary hardwaresuch as pulls, closers, kickplates, coordinators, gaskets, etc.Although

8、these hardware components may not influence blastresistance performance, the specifier may wish to verify thatthese items do not dislodge from the door or frame during a testand become a flying debris hazard.1.5 For doors equipped with a vision lite, the door shall beevaluated using the Door Respons

9、e Damage Categories intro-duced in section 1.3 and defined in Table 1 and the glazing andglazing system of the vision lite shall also be evaluated usinga No Break, No Hazard, Minimal Hazard, Very Low Hazard,Low Hazard and High Hazard rating system. Refer to section7.5 and Table 2 for glazing hazard

10、definitions.1.6 This method is intended to test the blast capacity of adoor assembly from a shock wave. It does not attempt toaddress all testing required of door assemblies. These tests mayinclude, but are not limited to, charge-in-contact blastresistance, forced entry resistance, bullet resistance

11、, fireresistance, sound attenuation, and gas or water leakage. Thesetypes of tests are not covered by this test method.1.7 This test method does not verify the blast performanceof the wall that a tested door will be placed in.1.8 The values stated in SI units (International System ofUnits) are to be

12、 regarded as the standard. The values given inparentheses are provided for information only.1.9 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 pract

13、ices and determine the applica-bility of regulatory limitations prior to use.2.

Any permanent deformation shall be wi

18、thin 3 mm (18 in.) of the pretestcondition. The door must be checked that it is operable by unlatching and swingingthe door open and then closed and latched. The door can be secured. The externalportion of the frame, frame anchorage, latches, and hinges shall not show any visibledamage. If strain ga

19、uges were used, the recorded stresses in the door material arewithin the specifiers acceptable limits.IDamaged butOpenableThe door panel, the frame, and/or the hardware has acceptable permanentdeformation or damage; however, the door remains openable. The door must bechecked that it is openable by u

20、nlatching and swinging the door open far enough toallow ingress / egress. Acceptable permanent deformation or damage and degree ofopening to permit ingress / egress is determined by the specifier based on the enduse of the door.IINon-catastrophicFailureThe door may get lodged into the frame from the

The door may be inoperable and may hinder ingress / egress.Acceptable permanent deformation or damage is determined by the specifier basedon the end use of the door. The door and hardware components are not permitted todetach from the frame and be t
