This specification presents the minimum fabrication and quality requirements for brazing of aluminum and aluminum alloys. Its purpose is to standardize brazing process requirements and control brazed joint quality for all applications for which brazed joints of assured quality are required. This document establishes the minimum requirements for processes and products with a minimum of explanatory information so that sources of ambiguity are minimized. It assigns responsibility for the ultimate quality of the brazed product to a single organization and permits that organization to modify requirements if appropriate to the application. It requires proper documentation of any such modification.

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, and applicable federal and state regulations.

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.
