FERROALLOYS – SAMPLING AND SAMPLING PREPARATION FOR CHEMICAL ANALYSIS – FERROCHROMIUM, FERROSILICOCHOMIUM, FERROSILICON, FERROSILICOMANGANESE, FERROMANGANESE (FIRST REVISION) (ISO 4552-1:1987, IDT)
This part of ISO 4552 specifies the methods for sampling and sample preparation for the determination of the chemical composition of a consignment of ferrochromium, ferrosilico-chromium, 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 ISO 4552 specifies the methods for use with ferrotitanium, ferromolybdenum, ferrotungsten, ferroniobium and ferrovanadium.
