The contents of the corrigendum of March 2001 have been included in this copy.
Soft soldering fluxes — Test methods — Part 9: Determination of ammonia content
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.
Soft soldering fluxes — Test methods — Part 2: Determination of non-volatile matter, ebulliometric m...
The method specified is based on evaporating a weighed amount of the flux sample in an ebulliometer until the entire volatile part is driven off, which is determined by following the graph of distillation temperature against time. The flux residue is considered as the non-volatile content of flux. Applies only to flux with a non-volatile content of 10 % or more.
