I just got a notification that the ASTM procedure for Rockwell testing has been updated. Can't get any definitive info on the scope of change without buying a copy. Just among us chickens, we have better places to invest our money than a new copy of the standard unless there's something that actually affects us.

I did about 1/2 hour Google searching. Only info I could find was from 2018 suggesting that the ASTM committee was adding coverage for portable Rockwell testers. Anyone else have insight on this?

thanks,

Brad

The last sentence in A1.5.3.5 was required to still require the calculation of R during daily verification, even if the differences between the individual hardness values and certified value for a test block are all within the maximum error E tolerances marked on the test block.

This is the only change since E18-19 identified in the summary of changes provided at the end of the document.
