USGNN Original StoryGANA's Tempering Division Gets Down to Business

The Tempering Division met on Wednesday during the Glass Association of North America's (GANA) Fall Conference in Dallas.

The division's Optical Distortion Subcommittee reviewed a draft of its presentation "An Overview of Optical Distortion and Roller Wave Measurement in Glass."

"The good news is, we got a lot of good comments back, bad news it took us this long to get the feedback," commented Joel Feingold of Strainoptic Technologies Inc., subcommittee chair.

And, indeed, there was lots of feedback to discuss during the meeting. The question quickly came up as to the intended audience for the presentation. While it was suggested that it would be used as an internal association resource for continuing education at events such as the Glass Fabrication and Glazing Educational Conference, many committee members agreed that the presentation is not as yet ready for further distribution, such as for training new employees on distortion. Among the concerns of the presentation was that it did not rely heavily enough on recommendations set forth in ASTM C1048, Standard Specification for Heat-Treated Flat Glass—or, perhaps, too heavily.

"We need to get our head out of the sand … C1048 as it's drafted today is insufficient for today's problems," commented one listener.

Others worried that what is intended as merely an educational presentation set what could be construed as standard requirements for how to inspect for optical distortion and roller wave measurement.

As division chair Cliff Monroe of Arch Aluminum & Glass explained, "I think it's setting a precedent for what everyone should be processing their glass under … you don't process 1/8-inch glass the same way you process 6-mm … it's indicating a level of evaluation that could steer the wrong parties in the wrong direction and make it difficult to you to sell or market your product in the field. There's a lot of innuendo [about the equipment you need to have]."

Feingold agreed to make some revisions to the presentation prior to the next meeting, February 12-15, 2009, at the Palms Casino Resort in Las Vegas, to see if these differences can be resolved.

Also during the division's meeting the Marketing Committee had the opportunity to review a draft of the tempering video during their meeting. Each division is producing an educational video on its product; videos already exist on producing float glass, mirror and laminated glass with PVB (CLICK HERE to view those videos). Some group members expressed concern that the video shows only one technique for producing tempered glass so that while it would be suitable to show to architects and customers, it could not be used for training employees on tempering. The video will be sent out to the committee members for further review, so that dialogue can be strengthened for technical information.

Committee members also announced that the Design in Glass Awards for 2009 had been canceled due to lack of funds and submissions.

After an update on its recently released Caring for Today's Architectural Glass position paper, the Construction Subcommittee declared an executive committee, closing the meeting to committee members only, in order to provide an update on the group's interaction with the window cleaning industry and, more specifically, the International Window Cleaning Association.

During Glass Week in February, the subcommittee had discussed ways to get the word out about the damage caused on glass by metal scrapers. CLICK HERE to read that story.
