Penn State University will cease production of Hardgrove Grindability Index Reference Material (HGI RMs) on June 30, 2024. The D05.07 subcommittee agreed to ballot a change in the contact information in D409 A4.3.5 from PSU to the new producer, Standard Laboratories. This is a concurrent ballot (sub and main together) so this item can be approved as quickly as possible for uninterrupted reference material production. Other editorial and technical revisions can be addressed in work items immediately after publication. Only footnote 6 is being changed in this ballot and no other sections, unless they are required for reference.
