Withdrawn Rationale:
These test methods cover the chemical analysis of ferromanganese having chemical compositions within the following limits:
ElementConcentration, %
|
Arsenic0.30 max
Carbon7.50 max
Chromium0.50 max
Lead0.050 max
Manganese16.0 to 90.0
Phosphorus0.35 max
Silicon7.00 max
Sulfur0.050 max
Tin0.020 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jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in May 2005. This standard is being withdrawn without replacement because it does not have ILS supporting data and most laboratories are using instrumental techniques for analysis rather than the old wet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.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 5 and in special warning paragraphs throughout.
