Rationale

This standard is being reviewed in accordance with the ASTM five-year review requirement. Revisions were made to improve clarity and consistency of wording. Only changes (shown in red) in the table below are balloted. A marked up copy of the method is included for reference purposes. Some editorial changes may be simply rationalized. If required, the method will be renumbered by the editor which may not be reflected in the table below as these are editorial.
