1.1This guide covers the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural hazards, such as hurricanes, earthquakes, windstorms, impacts from wind-borne debris; and assaults such as burglary, air blasts, forced-entry attacks and ballistic attacks.

1.2While other glazing accessories and components are used in protective glazing, this document specifically describes the use of silicone sealants for protective glazing systems.

1.3This guide provides information useful to design professionals, architects, manufacturers, installers, and others for the design and use of silicone sealants for protective glazing systems.

1.4A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for protective glazing must successfully integrate the frame and its anchorage, glass, or other glazing materials, protective film or interlayer and silicone sealant into a high performance system. Compliance with code or other requirements can be determined through physical testing of the glazing system or through computer simulation.

1.5Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and airblast test requirements incorporate the use of silicone sealants specifically formulated, tested, and marketed for this application. Sealants that are commonly used today comply with Specifications C920 and C1184.

1.6This guide does not discuss sealants intended to protect against radioactivity or provide biological containment.

1.7The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.9This 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.
