NIST - Recommended Guide to Rockwell Hardness Testing

Published by the National Institute of Standards and Technology, the Recommended Practice Guide, Rockwell Hardness Measurement of Metallic Materials, is essential reading for anyone concerned with hardness testing.

Written by Samuel R. Low of the National Institute of Standards and Technology, this book contains detailed information on everything related to Rockwell Hardness testing, from test procedures to references for test block standards to direct and indirect verifications. This publication resolves several questions including the following:

  • How often should indirect verification be performed? (Page 54)
  • Should my hardness tester be "Directly Verified"? (Page 44)
  • Should machine hysteresis be checked? (Page 45)
  • How does the test cycle time affect hardness readings? (Page 27)
  • What about force verification? (Page 45)
  • What happens if the machine forces are adjusted? (Page 45)
