Work Item
ASTM WK93818
Revision of E140-12B(2019)e1 Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness
Rationale
These proposed changes clarify E140 section 7 and were proposed during subcommittee discussion of a prior E92 ballot. (a) Make section 7.1 a note (b) Use E92 Section 9.2 as a header paragraph for E140 section 7 (c) Incorporate E92 section 9.2.2 into section 7. These changes to E140 are intended to be appropriate to propagate into E92, E10, and E18 when those documents are next revised.
