Chemical Testing

In this case instrument response must always be veri? Precision and Bias This titanium hydrogen reference material should have a hydrogen content greater than or approximately equal to the unknown samples within the scope of this test method 0.

The mid-range material must have a hydrogen concentration that is above the limit of zstm, but below that of the high calibration point, preferably as close to the mid-point of the calibration curve as possible. This cannot be corrected by making adjustments to the instrument.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Specimens must be of an appropriate size to? Treat each specimen as directed in Standard Test Method f The data are presented in Table 1. NOTE 3—Regardless of the method used, the sample must not be allowed to overheat, as this will adversely affect the results of the analysis.

Use a fresh crucible each time. No other units of measurement are included in this standard. ASTM D D Standard Reference Material: The accuracy of this test method is largely dependent upon the absence of bias in the hydrogen values assigned to the reference materials and upon the homogeneity of these materials.

Six instruments were of the thermal conductivity hydrogen measurement system con? Current edition approved Aug. In the absence of bias among the reference materials, the average result for this reference material should agree with the certi? 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.
