This document is not anASTM standard and is intended only to provide the user of anASTM 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
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 Definitions:
accuracy—the agreement between an experimentally determined value and the accepted reference value. In chemical work, this
term is frequently used to express freedom from bias, but in other fields it assumes a broader meaning as a joint index of
precision and bias. To avoid confusion, the term bias will be used in appraising of the systematic error of test methods for
industrial chemicals. See also bias. E180, E 180, E15.04
ash—the residual inorganic matter obtained on ignition of a sample in air at a specified temperature. E347, E 347, E15.51
