The Glass Association of North America (GANA) wrapped up its fall conference last Friday which included a variety of discussions surrounding glass products.

Within the technical committee, chaired by Mike Rupert of PPG Industries, the group had a number of documents to discuss. These included the efforts of a task group chaired by Jeff Nixon of Glass Coatings and Concepts to update the Engineering Standards Manual. Nixon reported that they are hoping to have a ballot out by Thanksgiving. Rupert next gave a report on the

Applications for Heat-Treated Glass glass informational bulletin (GIB). He said there are still a few editorial comments to be reviewed and expects the document to be published by the end of the year.

There are also a number of other documents in the works for the division. These include a Heavy Glass Door design guide, as well as Guidelines for the Production of Heat-Treated Glass.

Chuck Wencl of Viracon reported that the Methods of Measuring Optical Distortion in Heat-Treated Flat Architectural Glass GIB has been published. He posed a question to the group regarding the development of a related standard.

“If we don’t create a standard in the industry, someone else is going to,” said Wencl. The group decided to keep the task group open for further consideration.

Also discussed during the meeting was the update to the Proper Procedures for Cleaning Architectural Flat Glass Products, which GANA is doing with the International Window Cleaning Association. The group is planning a task group meeting in the next 30-45 days, and hopes to have the document finalized by the end of the year.

Under new business, Dave Evans with Guardian Industries provided a report on efforts to update ANSI Z97.1 with new language on testing bent, tempered glass. The proposed language notes that edges will remain supported and the specimen will be tested with the convex side facing up

The group also noted that there have been efforts within ASTM to update E1300 to include structural glass.

The group also heard two presentations. One was given by Dr. Stephen Morse of TexasTech University, who discussed some of the various topics that are being considered as far as changes to ASTM E1300, including heat-treated glass design. Joel Feingold of Strainoptics spoke on “Measuring Surface Edge Compression to Comply with ASTM and International Standards.”
