Title
Standard Practice for Specifying an Equivalent 3-Second Duration Design Loading for Blast Resistant Glazing Fabricated with Laminated Glass
ASTM International
Publication Date:
Aug 10, 2003
Scope:
This practice sets forth a method to specify an equivalent 3-second
design loading suitable to use
with Practice E 1300 to select the thickness and type of blast
resistant glazing fabricated with
laminated glass to glaze a fenestration.
This practice applies to blast resistant glazing fabricated using
laminated glass only, including
single laminated glass and insulating glass fabricated with laminated
glass.
This practice assumes that blast resistant glazing shall be adhered to
its supporting frame using
structural silicone sealant or adhesive glazing tape. The width of the
structural silicone sealant
bead shall be at least equal to but not larger than two times the
thickness designation of the
glass to which it adheres. The width of glazing tape shall be at least
equal to two times but not
more than four times the thickness designation of the glass to which
it adheres.
This practice assumes the framing members shall restrict deflections
of edges of blast resistant
glazing they support to L/160 under the equivalent 3-second duration
design loading as determined
herein, where L denotes the length of the supported edge.
This practice assumes the framing system supporting the blast
resistant glazing shall attach
mechanically to the structural framing system with fasteners that will
resist forces generated by a
uniform load acting on the blast resistant glazing that has a
magnitude at least 2.0 times the
magnitude of the 3-second equivalent design load as determined herein.
The equivalent 3-second design load as determined herein shall not
apply to the design of
monolithic glazing, plastic glazing, or security film applied to
existing glazing configurations in
an attempt to achieve blast resistance.
The values stated in SI units are to be regarded as the standard.
Values given in parentheses are
for information only. For conversion of quantities in various systems
of measurements to SI units
refer to ANSI IEEE/SI 10.
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.
