This standard describes the test methods used to obtain brazed strength data of the short-time testing of single-lap joints in shear, butt-tension, stress-rupture, creep-strength, four-point-bending, and ceramic-tensile-button specimens. Specimen preparation methods, brazing procedures, testing techniques, and methods for data analysis are detailed. Sample forms for recording data are presented. A graphical method of data presentation relates shear stress to overlap distance..
Scope : The purpose of this standard is to describe the test methods used to obtain reliable data on the strength of metaltometal, metal-to-nonmetal, and nonmetal-to-nonmetal brazed joints. Test specimens should be prepared using consistent and proper fabrication and brazing practices. Interpretation of the test results is the responsibility of the user. It is important that the user of these tests maintain sufficient documentation of the materials, brazing parameters, and test conditions. This documentation will be required when comparing the results with the joint strengths obtained by others using this standard method. General use of this standard method may permit a compilation of brazed joint strengths and brazing design criteria at some future time. Safety and health issues and concerns are beyond the scope of this standard and therefore are not fully addressed herein. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes. This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The latter are shown within brackets [ ], or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore, each system shall be used independently.
