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 precautionary statements are given in Section 5 and 26.8.1, 27.4.1.1, and 36.3.1.
WITHDRAWN RATIONALE
These test methods cover the chemical analysis of silicon and ferrosilicon having chemical compositions within established limits.
Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, these test methods were withdrawn in September 2006.
