New ASTM E18 2014 Edition released – Rockwell Hardness

The popular ASTM E18, “Standard Test Methods for Rockwell Hardness of Metallic Materials,” has just been updated.  The new 2014 Edition is available from Document Center Inc. in either paper format or for pdf download.  The 38-page standard covers both the Rockwell Hardness and the Rockwell Superficial Hardness tests.  It includes both the requirements for the testing machines and the procedures for the tests themselves.

This new ASTM E18 2014 Edition cancels and replaces the previous 2012 Edition (I blogged on that edition when it was released.)  There are 10 notable changes to this update.  They are all contained in the Annex A3, Standardization of Rockwell Indenters (one of the mandatory Annexes):

1. Section A3.4.5.1 was revised,
2. Section 3.4.5.4 was revised,
3. Section A3.5.3.2 was revised,
4. Section A3.5.3.7 was revised,
5. Section A3.8.2 was added,
6. Section A3.8.3 was added,
7. Section A3.9.1.6 was added,
8. Section A3.9.3.6 was added,
9. Table A3.4 was added, and
10. Table A3.7 was added.

FYI: Section A3.4 covers ball identers, Section A3.5 covers Class B diamond indenters, Section A3.8 covers marking and Section A3.9 covers the certificate.  The new Table A3.4 addresses test blocks used for singular or limited scale ball indenter performance verification, plus maximum tolerances, for standardized reference blocks.  And the new Table A3.7 covers the same thing for Class A or reference indenter.
