The latest, up-to-date edition.
Sets out a spectrophotometric method for the determination of iron in aluminium and aluminium alloys in the range 0.05 percent to 2.5 percent. This Standard is technically equivalent to ISO 793:1973 but contains precision data obtained from an interlaboratory test program carried out in Australia.
This Standard sets out a spectrophoto-metric method for the determination of iron in aluminium and aluminium alloys. This method is applicable to the determination of iron contents between 0.05% and 2.50% (m/m) in aluminium and aluminium alloys. It does not apply completely to the following special cases, for which it should be modified as described in Appendix A or Appendix B: (a) Unalloyed aluminium, aluminium-silicon alloys and any other aluminium alloy that is not easily attacked with hydrochloric acid (see Appendix A). (b) Alloys containing a copper content greater than 5%, zinc content greater than 4%, nickel content greater than 2% or alloys with a proportional combination of these elements greater than 5% total (see Appendix B).
