ASTM E18 2017 Rockwell Hardness

ASTM E18, Standard Test Methods for Rockwell Hardness of Metallic Materials, has been revised again.  The new 2017 Edition is available from Document Center now.  It is a copyright document and can be purchased in paper format or for pdf download.  It can also be included in our Standards Online cloud access subscription service.

This is one of our best selling standards here at Document Center Inc.  I last blogged about it when the 2016 Edition was released (ASTM E18 2016 Update Available).  It provides you with the test methods to use to determine the Rockwell hardness and the Rockwell superficial hardness of metallic materials.

You will also find complementary information in the Appendices.  Appendix X1 is a list of ASTM standards that give approximate hardness values corresponding to tensile strength values.  Appendix X2 contains examples of procedures for determining Rockwell hardness uncertainty.

The changes in the new 2017 Edition of the ASTM E18 are not extensive.  They center on a new Note A1.4 and changes in Clauses A1.5.2.8, A1.5.3.9, A2.8.1.8 and A2.8.2.9.  However, you may have trouble spotting them.  Use the Redline edition to confirm all updates.  It costs a bit more, but you not only get the clean copy of the 2017 Edition but also the “marked-up” copy of the 2016 one as well.

Copyright standards should always be purchased from an authorized distributor like Document Center Inc.  Search for current and obsolete editions of ASTM Standards at our webstore, www.document-center.com.  It’s easy to order online.  Here is a direct link to the order page for ASTM E18 for your convenience.
