Standard Test Method for Determination of Hydrogen in Titanium and Titanium Alloys by Inert Gas Fusion Thermal Conductivity/Infrared Detection Method

SIGNIFICANCE AND USE
5.1 This test method is intended to test for compliance with compositional specifications. It is assumed that all who use this test method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory.
SCOPE
1.1 This test method applies to the determination of hydrogen in titanium and titanium alloys in concentrations from 0.0006 % to 0.0260 %.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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. For specific hazards, see Section 9.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

4. Summary of Test Method
4.1 The specimen, contained in a small, single-use graphite crucible, is fused under a flowing carrier gas atmosphere. Hydrogen
present in the sample is released as molecular hydrogen into the flowing gas stream. The hydrogen is separated from other liberated
gases such as carbon monoxide and finally measured in a thermal conductivity cell.
4.2 Alternatively, hydrogen is converted to water by passing the gas stream over heated copper oxide and subsequently
measuring in an appropriate infrared (IR) cell.
4.3 This test method is written for use with commercial analyzers equipped to perform the above operations automatically and
is calibrated using reference materials of known hydrogen content.
5. Significance and Use
5.1 This test method is intended to test for compliance with compositional specifications. It is assumed that all who use this test
method will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the
work will be performed in a properly equipped laboratory.
