This standard describes the test methods used to obtain reliable data related to external braze features and microstructural information to ensure compliance to the requirements of the following braze processes: Torch Brazing, Induction Brazing, Furnace Brazing, Resistance Brazing, Dip Brazing, Infrared Brazing, and Diffusion Brazing.

This standard also covers evaluation of joints, prepared and brazed according to a Brazing Procedure Specification and the applicable brazing specification utilizing samples that are representative of the part, or an actual part, at the discretion of the Organization Having Quality Responsibility (OHQR) or the Organization Performing the Brazing Operation (OPBO). Evaluation may be performed using external visual inspection, various metallographic techniques, and destructive testing such as peel testing.

Figures and illustrations are included wherever appropriate to clarify the expectations and interpretations of the data. This document provides information to assist in standardizing the evaluation and interpretation of brazed joint features but the acceptability of those features will be governed by the applicable brazing process specification, engineering drawing requirements, and the OHQR.
