1.1The existing condition of SSG installations should be periodically evaluated in-situ to detect if problems exist, and if so found, to address them before they become severe or pervasive. Evaluation of existing SSG installations is required by certain building codes and local ordinances. This guide provides a program to evaluate the existing conditions, lists typical conditions that may exist, and suggests times when such evaluations are appropriate. Presently, only a silicone sealant that is specifically formulated, tested and marketed as a structural glazing sealant is allowed for structural sealant glazing. The committee with jurisdiction over this standard is not aware of any comparable standards published by any other organizations.

1.2This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
