BS EN ISO 6508-2:2015 Metallic materials. Rockwell hardness test. Verification and calibration of testing machines and indenters

BS EN ISO 6508-2:2015

Metallic materials. Rockwell hardness test. Verification and calibration of testing machines and indenters

Status : Under review, Current   Published : March 2015



What is this standard about?

This is the second in a three part international standard on the Rockwell test for metallic materials. The other two parts are: 

  • Part 1: Metallic materials. Rockwell hardness test. Test method
  • Part 3: Calibration of reference blocks

Who is this standard for?

  • Rockwell hardness testing machine and indenter manufacturers
  • Users of the Rockwell hardness test

Why should you use this standard? 

This part of ISO 6508 specifies two separate ways to verify testing machines – direct and indirect – for determining Rockwell hardness in accordance with Part 1.

The direct verification method is used to determine whether the main parameters associated with the machine function, such as applied force, depth measurement and testing cycle timing, fall within specified tolerances.The indirect verification method uses a number of calibrated reference hardness blocks to determine how well the machine can measure a material of known hardness.

The indirect method may be used on its own for periodic routine checking of the machine in service. 

This part of ISO 6508 applies to stationary and portable hardness testing machines. 

NOTE: Attention is drawn to the fact that the use of tungsten carbide composite for ball indenters is considered to be the standard type of Rockwell indenter ball. Steel indenter balls may continue to be used only when complying with BS EN ISO 6508-1 Annex A.

What’s changed since the last update?

This standard was systematically reviewed by technical experts to ensure its continued market relevance. This is a technical revision of the 2005 version which has been withdrawn.
