1. Rationale
This method as written here has not been previously balloted. Subcommittee D0204-H carried out a study limiting the columns and conditions used in the Method D2887-06.One of the conditions was to increase the oven heating rate and the carrier flow resulting in an 8 minute analysis. With the restricted columns and operating conditions, an ILS (ILS 158) was carried out. The data obtained from this study was added to the Appendix (X6) of D2887-06 including the Precision Statement of the ILS 158 study in a ballot in 2008. In the Subcommittee ballot the method received negatives citing the contradictory position of 2 precision statements, especially when one of the precision statements was located in an Appendix. Subcommittee discussions on whether to have a separate method or to have a two part method resulted in an official ballot where it was recommended to have a Part B. ASTM Methods having a Part A, Part, B and even a Part C are not new. Part A has remained intact except for the Scope where the justification of adding Part B is described. The entire method is presented in the ballot since sections of Part B are referenced to Part A. The method presented here is the result of dividing D2887-06 into Parts A and Parts B.
