1.1 This specification covers 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 units used in structural sealant glazing (hereinafter referred to as SSG). Hereinafter, the term "insulating glass" will be referred to as IG. Presently only certain silicone sealants are recognized as having the necessary durability for use as secondary sealant in IG units in structural glazing applications.
1.2 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
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.
