ASTM F19

This test method establishes the standard procedures for conducting tension and vacuum tests on metal-ceramic seals to determine the bond strength of brazed, metalized ceramics. This test method is, however, not to be considered as an absolute tension test for the ceramic. This method requires the use of appropriate testing machines and various types of gripping devices.
