- Scope
- This document specifies a method for the determination of phosphorus, manganese, chromium, copper and cobalt contents in ferronickels, by inductively coupled plasma (ICP) optical emission spectrometry, within the ranges specified in Table 1. This method is applicable to all grades of ferronickels specified in ISO 6501. Table 1 — Application ranges of the elements to be determined Application range % (mass fraction) Element Phosphorus 0,009 to 0,045 Manganese 0,02 to 1,0 Chromium 0,076 to 1,86 Cobalt 0,24 to 1,4 Copper 0,02 to 0,07
