New Technical Interpretations
for ANSI Z97.1 Issued
April 28, 2011
Two new technical interpretations have been issued for the 2009 version of the ANSI Z97.1 standard. The first, TI-04.11.001, clarifies the language related to laminated and organic glass weathering of colored products, indicating that clear products qualify colors. The second, TI-04.11.002, resolves the current question around the utilization of the center punch fragmentation test for tempered safety glass and the particle count.
The TI-04.11.001 interpretation notes that "when the thinnest construction of all components of laminated and organic coated glasses have passed the applicable weathering requirements and subsequent evaluation thicker components and colored components will be deemed qualified for weathering compliance."
Likewise, TI-04.11.002 says "no one particle shall be longer than 4 inches excluding an area of radius 4 inches centered on the impact point and a border of 1 inch around the entire perimeter/edge of the test specimen."
Both interpretations will also be available through the ANSI Z97.1 website.
