ASTM C1392-20,Standard Guide for Evaluating Failure of Structural Sealant Glazing.
ASTM C1392-20 covers a screening approach to detect failure (adhesive or cohesive) of a structural sealant in a structural sealant-glazed window, curtain wall, or other similar system.
Summary of Guide
This guide uses deflection measurements obtained from localized applied loads to determine locations of sealant failure in an installed structural sealant glazing system.
Initially, the deflection of an existing lite that is fully adhered by a structural sealant is measured when a discrete edge of the lite is loaded laterally. Subsequently, at a few selected lites, the structural sealant is cut intentionally to simulate failure. and the deflection of the lite is measured at the same lateral load. This provides the basis for determining during subsequent tests of other lites in the system whether the sealant has failed.
