This specification describes the properties of cold, liquid-applied, single or multi-component, chemically curing, elastomeric sealants used as the secondary seal of sealed insulating glass units, hereinafter referred to as the "sealant" (see Fig. 1). These sealants are intended to be a structural component of sealed insulating glass (IG) units used in structural sealant glazing (hereinafter referred to as SSG). Typical designs and considerations can be found in Guide C 1249. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in SSG applications.
This specification does not describe all of the necessary
properties of the sealant. Only those properties for which there
are ASTM test methods and industry-agreed-upon
This specification only addresses the durability of the secondary edge sealants for structurally glazed insulating glass units. Durability of sealed insulating glass units can be found in specifications and guides that reside within ASTM Committee E06.
The committee with jurisdiction for this standard is not aware of any comparable standard published by other organizations.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.
