1. Rationale
This document is up for its 5 year review, and we can take this opportunity to make some adjustments to keep it in accord with related standard, E 384, which formerly was known as Test Method for Microhardness of Materials. E 384 was revised by ASTM Committees E-04 Metallography, which had jurisdiction, and Committee E-28 Mechanical Testing, which had jurisdiction of Test Method E 92, Vickers Hardness. It is now called E 384-11, Standard Test Method for Knoop and Vickers Hardness of Materials (2011). The proposed revision to C 1326 below is to update it and bring it into consistency with E 384 as appropriate
