European standards/technical guides

A prerequisite for the successful use of ferrous slag in the long term is that it meets the requirements for technical and environmental aspects given in harmonised European or national standards. Starting in 1990, most of the requirements given in national standards relevant for the building industry have been harmonised and replaced by European standards. The most important European standards for today’s use of slag in the construction sector and as fertilizer are given in the following table.
