Abstract
A method for producing an inner tin film on the surface of plumbing components, such as those made of red brass or yellow brass, for drinking water supply. The lead content on the inner surface of the hollow component parts is first reduced by treatment with an acid-based aqueous reducing solution. For this purpose, chloride-free and sulfate-free, non-oxidizing hydracids may be used. The hollow component parts are subsequently chemically internally tinned.
