    Rationale

    E1685-13 will reach the end of its active status in 2020. It must be reapproved by year end else it will formally be withdrawn. The document was balloted for reapproval in February 2020, but received a negative vote cast by Cory Hamilton, Struers Inc., Westlake, OH. He cited various textural deficiencies and reliance on a calibration procedure document that was formally withdrawn in 2012. William Luecke also registered a comment citing some concerns with the grammatical format of the document. An examination of E1685-13 by E28.13 Subcommittee Chair Gary Schajer confirmed that the comments were well founded and that several other details in the document could also benefit from review and revision. An ad-hoc group of Subcommittee members comprising Gary Schajer, Cory Hamilton, William Luecke and Adam Cobb (a specialist in ultrasonic measurements) was convened to review E1685-13 in detail and to propose a revised version that addresses the various concerns. During March, April and May 2020 the committee members exchanged substantial email correspondence and had two online meetings to formulate appropriate proposals for revisions. They reached consensus on all points and prepared the attached proposal for revisions. Subcommittee members Cory Hamilton, William Luecke and Adam Cobb all freely gave substantial time and effort to the revision of E1685-13. Adam Cobb kindly joined Subcommittee E28.13 specifically to contribute to the work. Sincere thanks to all, their work and commitment is very much appreciated.
