Standard Test Method for Determining the Tensile Properties of an Insulating Glass Edge Seal for Structural Glazing Applications
1.1 This test method covers a laboratory procedure for quantitatively measuring the tensile strength, stiffness, and adhesion properties of insulating glass edge seals that are used in structural sealant glazing applications. Edge seals for these applications use a structural sealant to bond both glass lites and the edge spacer into a monolithic sealed insulating glass unit. In typical applications, the structural sealant acts to hold the outside lite in place under wind and gravity load and to maintain the edge spacer in its proper position. Hereafter, the term “insulating glass” will be abbreviated as “IG.”
1.2 The characterization of the IG secondary sealant properties, as defined by this test method, are strongly dependent on glass and edge spacer cleaning procedures, IG spacer profile, location of spacer, and primary IG sealant application. Users of this test method must recognize that the IG edge seal assembly influences the secondary sealant properties.
1.3 The values determined by this test method will be characteristic of the particular edge seal assembly that is tested.
Note 1—Presently, only elastomeric, chemically curing silicone sealants specifically formulated for use as the secondary seal of IG units are recognized as having the necessary durability for use in structural sealant glazing applications.
1.4 The values stated in SI (metric) units are to be regarded as the standard. The inch-pound values given in parentheses are approximate equivalents, provided for information purposes.
1.5 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 limitations prior to use.
