This document specifies three test methods for investigating brazeability. A spreading test shows testing method with measurement of the spread area of the filler metals. A T-joint test describes a scheme to construct a T-shape design by the test pieces and a testing method. A varying gap test describes a test piece and a testing method for assessing the influence of the various parameters which can influence brazing during manufacture as a function of clearances.
