ASTM C1087-16 PDF Download

ASTM C1087-16 is a standard test method that is used to determine the compatibility of liquid-applied sealants with accessories used in structural glazing systems. In structural sealant glazing systems, the sealant serves as both a structural adhesive and a primary weather seal. Therefore, it is crucial to ensure the integrity of the adhesive bond.

The standard test method involves a laboratory screening procedure where the sealant is exposed to heat and ultraviolet light and then evaluated for compatibility with accessories such as dry glazing gaskets, spacers, shims, and setting blocks. The test method focuses on three parameters: changes in the color of the sealant, changes in the adhesion of the sealant to glass, and changes in the adhesion of the sealant to the accessory being tested.

The color and adhesion changes observed in this test method are considered indicative of potential issues that may occur in actual use. It is important to note that there is currently no comparable ISO standard available for this test method.
