ASTM C 1564 : 2003

1.1 This guide is for the use of silicone sealants in protective glazing systems for building construction. Protective glazing includes systems designed for use in applications subject to natural disasters such as hurricanes, earthquakes, windstorms and forms of forced entry such as blasts, burglary and ballistic attack.

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

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

1.4 A silicone sealant is only one component of a glazing system. A glazing system that meets the testing and code requirement for impact 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.

1.5 Glazing systems using silicone sealants that have successfully met the test requirements for missile impact and bomb blast 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 C 920 and C 1184.

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

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

This 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 and health practices and determine the applicability of regulatory requirements prior to use.
