This part of IS0 4552 specifies the methods for sampling and sample preparation for the determination of the chemical composition of a consignment of ferrochromium, ferrosilicochromium, ferrosilicon, ferrosilicomanganese or ferromanganese. NOTE - For purposes of sampling, ferrochromium is subdivided into non-crushable and crushable alloys. Low-carbon and certain mediumcarbon ferrochromiums are non-crushable alloys; medium-carbon and high-carbon ferrochromiums are crushable alloys. Part 2 of IS0 4552 specifies the methods for use with ferrotitanium, ferromolybdenum, ferrotungsten, ferroniobium and ferrovanadium.
