Twin City Testing Now Tests for Detention Glazing
Stork Twin City Testing (TCT) in Des Moines, Iowa, has expanded
its capabilities to include testing for window glazing in correctional
facilities and detention facilities to the standard ASTM F1915-05,
"Standard Test Methods for Glazing for Detention Facilities." "
It sounds like there are not a whole lot of people who do the testing,
but that's why we took it on," says Brian Escherich, product evaluation
department manager. When one large customer requested detention
facility testing, the company created designed and built a special
fixture to carry out the test methods.
F1915-05 determines the ability of detention glazing to perform
at or above minimum acceptable levels to restrict inmate passage
to unauthorized areas, to confine inmates, to delay and frustrate
escape attempts and to resist vandalism.
"The detention glazing testing protocol is a simulation of what
inmates could do in their environment. What kind of tools would
they come upon or things they could use to gain access to the outside,"
Escherich explains that the pass/fail criteria for the test is
the ability to pass a 5- by 8- by 8-inch rectangle through an opening
in the glass. "It's fairly large," he says. "Basically, if an inmate
could get his hand and arm through there they would be able to manipulate
a lock or something like that."
The test involves impacting the products with an 80-pound impactor
that simulates blunt force, as well as a sharp point to simulate
a tool such as a fireman's axe.
"The samples are also subjected to extremes of temperature to
simulate possible scenarios," Escherich says. The glass products
must be able to withstand fires in addition to cold temperatures,
which could potentially be lowered by discharging a fire extinguisher.
According to Escherich, "Secure, protective glazing is an important
tool for law enforcement and correctional facility operators. With
this method, we test samples of glazing with tools that are representative
of similar tools or materials that may become available to inmates
within the secure perimeter of detention and correctional facilities
and which could be used to inflict similar damage to the glazing
