GANA Announces Center-Punch Fragmentation Test Method

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 standard procedure."

"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."
