Standard Guide for Use of Silicone Sealants for Protective Glazing Systems

Importancia y uso:

4.1 Guidelines are provided for the use of silicone sealants in protective glazing. Protective glazing incorporates various forms of glazing that are not covered in Guides C1401 and C1193. The requirements for a sealant in protective glazing are similar to the requirements for structural sealant glazing. However, for certain applications, such as missile impact and blast resistant glazing, sealant requirements may be greater. Modes of failure for blast resistant glazing can be different than the modes of failure for missile impact glazing. Of particular concern is the outbound glazing support loading from blast wave negative phase pressure or the dynamic rebound of the glazing, or both.

4.2 Many types of protective glazing systems are relatively new and the test methods and standards for protective glazing are continually evolving. Because the demands on a sealant in protective glazing systems are changing, guidelines are necessarily general in many instances.

4.3 As a component of a glazing system, the sealant can be a factor in whether a glazing system meets the requirements of a specific test method but other factors such as the frame and glazing type, may be of greater influence.

4.4 The designer of a protective glazing system should consult with the various manufacturers of the component materials. The experience and judgment of the glazing system designer working with the sealant manufacturer and other component manufacturers, can ultimately determine whether a specific glazing system will successfully meet a specific test requirement.
