Причина отмены

These test methods cover the chemical analysis of ferromanganese having chemical compositions within the following limits:

ElementConcentration, %Arsenic0.30 maxCarbon7.50 maxChromium0.50 maxLead0.050 maxManganese16.0 to 90.0Phosphorus0.35 maxSilicon7.00 maxSulfur0.050 maxTin0.020 max

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in May 2005. This standard is being withdrawn without replacement because it does not have ILS supporting data and most laboratories are using instrumental techniques for analysis rather than the old wet chemical methods.
