Draft 6 is the latest version of the Sequence IVA Test Procedure. It was issued in Information Letter 02-1 and is the latest version of this document that is available at this time. At this time, the Sequence IVA Test Procedure has not been published as an ASTM Test Method. Work towards that goal is in process. If you have any questions, please contact Michael Kasimirsky at mtk@tmc.astm.cmri.cmu.edu or 412-365-1033.
