This standard is being balloted for withdrawal with no replacement because, over the past year, discussions at E28.06 Subcommittee meetings have failed to identify anyone using the Practice. It was reported that the only manufacturer of the Scleroscope in the US has stopped selling or servicing the instruments.However, E448 was downloaded about 300 times over the past five years, and there are three ASTM Standards that reference E448. The three standards and the Subcommittees having jurisdiction are the following: ASTM A427/A427M-10 Standard Specification for Wrought Alloy Steel Rolls for Cold and Hot Reduction: (Subcommittee A01.06). ASTM E140-12be1 Standard Hardness Conversion Tables for Metals Relationship Among Brinell Hardness, Vickers Hardness, Rockwell Hardness, Superficial Hardness, Knoop Hardness, Scleroscope Hardness, and Leeb Hardness: (Subcommittee E28.06). ASTM C886-98(2010)e1 Standard Test Method for Scleroscope Hardness Testing of Carbon and Graphite Materials: (Subcommittee D02.F0). Subcommittees A01.06 and D02.F0 will be notified of this ballot and will be asked for comments.
