Причина отмены

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this test method was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

This method for the chemical analysis of titanium and titanium alloys is primarily intended to test material for compliance with specifications of chemical composition.

It is assumed that all who use this method will be trained analysts capable of performing common laboratory procedures skillfully and safely, and that the work will be performed in a properly equipped laboratory.

The method is designed to give the maximum flexibility analyzing elements in the titanium matrix. Thus options are given in calibration and analysis to accommodate the variety of ICP and DCP spectrometers and their auxiliary systems.
