Rationale

Industry practitioners are looking for updated procedures with more specific guidelines for confirming the relative humidity conditions outlined in Section 6.2.1. A separate ballot proposes to update the reference in ASTM E119 to determine the relative humidity within hardened concrete test specimens. This ballot proposes to move reference to a 1955 ASTM Proceedings paper authored by C.A. Menzel to the Section X5.7 Appendix/Commentary. Future ballots may provide additional procedural guidance information as appropriate.
