glass substrate specimen for ASTM C961 lap shear sealant testing

ASTM C961 Glass Lap Shear Specimens

Glass substrates (also called specimens or panels) used in testing by ASTM C961 (Lap Shear Strength of Sealants). Each substrate is 1" x 3" x 0.25" and is made from clear float glass (also known as annealed glass). ASTM C961 uses two substrates to make a single adhesive test specimen assembly, and the test uses six specimens (twelve substrates total). ASTM C961 substrates may be made from other materials; contact Metaspec to learn more.
