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.

This document specifies the performance requirements for fluxes in solid, liquid and paste forms
intended for use with soft solders.
NOTE 1 ISO 9454-1 specifies the requirements for labelling and packaging as well as the coding system for the
classification of the fluxes.
NOTE 2 Some of the fluxes intended for inert gas and vapour phase soldering may not pass some of the criteria
in Tables 1 and 2.
Requirements for these fluxes are agreed between the purchaser and the supplier.

The principle of the method specified is to distil a prepared flux solution with sodium hydroxide to expel the ammonia present in the flux, to pass the resulting distillate into a standard sulfuric acid solution, to titrate the excess acid with sodium hydroxide solution and to calculate the ammonia content of the flux. Applies to fluxes of class 3.1.1 only, as defined in ISO 9454-1.
