Revision of D5230-21e1 Standard Test Method for Carbon Black—Automated Individual Pellet Hardness

Rationale

In the current state, this method's Precision & Bias statements happen to be exclusively based on SRB materials. Nonetheless the values are not to be understood as references, since there are no reference materials applicable to this test method. As this leads to confusion, it is suggested to add a clarifying note.
