ASTM C1487-02

Standard Guide for Remedying Structural Silicone Glazing

SCOPE
1.1 This guide provides recommendations for remedying existing structural sealant glazing (hereinafter called SSG) installations in situ. Remedial work may be necessary when a lite of glass is replaced, for routine maintenance, or after distress is discovered. This guide focuses on large-scale remedies.
1.2 Committee C24 is not aware of any comparable standards published by other organizations.
