IGMA Proposes Reference to ASTM E1300 in Canadian Construction Codes

The 2010 Canadian National Model Construction Codes has been undergoing a review process that includes proposed changes from the Insulating Glass Manufacturers Alliance (IGMA). Among the proposals is IGMA’s code request to reference ASTM E 1300, Standard Practice for Determining Load Resistance of Glass in Buildings.

“The glass strength standard in Canada (CGSB 12.20) has not been updated in more than 20 years. As such it doesn’t address many of the glass configurations on the market, including triple-glazing,” says Margaret Webb, executive director for IGMA. She says the code change request was submitted a few years ago and was considered too complicated to include in the 2010 NBCC. “So a task group was formed and has been working on the differences of the two standards and also how to level these differences,” she explains. “IGMA, in the persons of Bill Lingnell, Ray Wakefield and I, have worked closely with this task group to develop the current code language. This involved some face-to-face meetings and numerous conference calls. The recommendation of the task group was to reference ASTM E 1300 and CGSB 12.20 in the 2015 NBCC. This recommendation was accepted by the appropriate building code committees covering commercial and residential sections of the Canadian code.”

Following the current public review of the code, CCBFC Standing Committees will consider all comments and make final recommendations on each proposed change. Subject to approval by the CCBFC, the final changes will be published in the 2015 editions of the National Model Construction Codes. www.nationalcodes.nrc.gc.ca

Pennsylvania State University to Research Glass Strength Properties

The Usable Glass Strength Coalition (UGSC) awarded a $110,000 grant to Pennsylvania State University (PSU) in University Park, Pa., to research manufactured glass products’ strength properties. Titled “Controlling and Understanding Reactive Surface Sites on Multicomponent Glasses,” the project will be led by co-principle investigators Dr. Seong H. Kim, a professor of chemical engineering and associate professor of materials science and engineering, and Dr. Carlo Pantano, a distinguished professor of materials science and engineering.

Under the auspices of the Glass Manufacturing Industry Council (GMIC), the UGSC defines itself as a cross-industry coalition that aims to advance, develop and promote fundamental, precompetitive research applicable to increasing the strength of glass across all glass sectors; to provide an opportunity for glass researchers to develop expertise in areas suitable for industrial applications; and to develop tools and measurement techniques for the advancement of glass science.

Research began October 1 and the initial funding is scheduled to last one year.
