This European Standard specifies six grey cast irons according to the tensile strength and six grey cast irons according to the Brinell hardness

Soil quality. Parameters for geochemical modelling of leaching and speciation of constituents in soils and materials - Extraction of amorphous iron oxides and hydroxides with ascorbic acid PAS 015 The base-band frequency response is1 Scope This part of ISO 12782 specifies the determination of the content of reactive iron in the form of amorphous iron oxides and hydroxides in soil and other materials by extraction with ascorbic acid. Other materials also include waste. The content of reactive iron can be used as input in geochemical models to represent the content of amorphous iron (hydr)oxides. NOTE Although the ammonium oxalate oxalic acid extraction (ISO 127823) is commonly
