Several years ago, the General Services Administration
(GSA) mandated a universal standard for measuring the
level of blast protection. The GSA developed criteria
for evaluation of acceptable levels of protection for
the glass fragment hazard. This criteria is part of
the comprehensive security criteria (GSA Security Criteria,
Final Working Version, January 1997) developed by the
GSA which includes physical security, electronic security,
and many other criteria for blast considerations. The
GSA has indicated a preference, but not a requirement,
for open-air high explosive testing rather than shock
tube testing. This is because current shock tube testing
methods cannot adequately emulate air blast waveforms
from real explosions and tend to be over-energetic at
the same peak blast pressure level versus real explosions.*
