Perspectives On Testing Security Glazing: Failure Limits

Mr. Jeffrey D. Granato and Mr. Ray V. Foss

Current security glazing testing technology is
reviewed in which the distinction and contrast is
made explicit between end-use performance,
product classification and materials response.
Testing security glazing to failure is investigated
and emphasized.
Cumulative damage impact fatigue concepts
and methods were developed based on repetitive
impacts on laminated glazing constructions at
energy levels below the single blow penetration
strength. This repetitive fatigue impact approach
more completely describes capacity of composite
constructions to resist failure modes.
When multiple impacts are relevant to the
end-use, performance is better represented by
specimen response to repeated impacts at energy
levels below single-blow impact strength.
Significance is an improved and expanded way
to test and describe end-use impact performance
to failure in security applications.
