Rationale

It has been 5 years since the Standard has had any changes. ASTM guidelines indicate if a Standard has gone 5 years without any activity, it should be reapproved. As part of the reapproval process, we are also reviewing “Definitions Specific to the Standard” and harmonizing definitions in that section when possible with other D02 Definitions (in D4175). In this Standard there are several “Definitions Specific to the Standard” with some presenting opportunities for harmonization.
