The Glass Association of North America's (GANA) tempering division
has announced the adoption and publication of specification number
TD 05-28-04, a new standard test method for center-punch fragmentation
of fully tempered flat glass.
The test method establishes a specified procedure for the destructive
fragmentation and evaluation of the fracture pattern of monolithic,
fully tempered flat glass products intended for use in architectural
safety glazing applications.
"Historically, fabricators have used fragmentation testing
as a part of their quality assurance programs despite the lack
of a precise industry recognized procedure," said Cliff Monroe
of Arch Aluminum & Glass, center-punch fragmentation subcommittee
chairman. "The new test method provides the needed industry
"While the new test method will allow for frequent in-plant
testing, it is not a substitute for complying with the safety
glazing requirements of the national industry standard ANSI Z97.1
or the federal specification CPSC 16 CFR 1201," added Greg
Carney, GANA technical director. "It is critical that fabricators
understand they must continue to test safety glazing materials
under the procedures and evaluation methods of the applicable
safety glazing standards."
