This standard is now in its 5th year since the last approval and is now due for revision/reapproval. Prior ballots had indicated that this standard should be a standard practice rather than a test method, as it only uses the data from another test method. The standard has been changed to a Practice in the title and text to reflect this. No technical changes were made.
