1.2 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 safety hazards statements are given in Section 9.
Significance and Use
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.
