Metallic materials - Hardness test - Part 2: Verification of Rockwell hardness testing machines (scales A - B - C - D - E - F - G - H - K) (included in prEN 10109)

Scope

This European Standard specifies a method of verification of testing machines for determining Rockwell hardness (scales A - B - C - D - E - F - G - H - K) in accordance with EN 10004-1. It describes a direct verification method for checking the main functions of the machine and an indirect verification method suitable for the overall checking of the machine. The indirect verification method may be used for other methods of hardness testing, it shall be verified independently for each method
