Significance and Use
Blast resistant doors are designed to protect against the problems and dangers created by a planned or accidental explosion or pressure leak. This test method will provide reasonable assurance to the specifier of the reliability of a door's structure, the restraining hardware, the frame, and the frame anchors when used in a blast resistant application.
1.1 This test method covers the structural performance of metal doors and frames and their restraining hardware (such as latches and hinges) used as a blast resistant barrier. This method involves applying an equivalent static pressure based on the characteristics of the specified blast pressure and structural properties of the door panel design.
1.2 The static tests are valid for the unit size tested or for smaller units of analogous construction. Extrapolation of test results for units larger than the test specimen are not permitted.
1.3 This standard test method is not applicable to tests where the forces are created by explosive charges, forced air from a shock tube apparatus, or any other method used to generate a dynamic load.
1.4 The proper use of this method requires knowledge of the principles of pressure, deflection, and when applicable, strain gauge measurement.
1.5 Using this method, specimens may be tested to determine ultimate static capacity or tested to specific static test loads.
1.5.1 Procedure A shall be used when a load-deflection curve is not required and a single load is applied.
1.5.2 Procedure B shall be used when a load-deflection curve is required and a single or multiple loads are applied.
1.6 The values stated in SI units are to be regarded as the standard. The values provided in parenthesis are for information only.
1.7 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.
