Active Standard: D7345 - 08
ASTM International Committee D02 and the Energy Institute (formerly the Institute of Petroleum) Test Methods Standardization (TMS) Committee have a long history of cooperation and have developed a number of joint and/or technically equivalent standards and interlaboratory study programs. Both ASTM and EI participated in the interlaboratory study which produced RR:D02-1621, which is the basis for the precision stated in D7345 Test Method for Distillation of Petroleum Products at Atmospheric Pressure (Micro Distillation Method), with the intent that this was a joint program, as discussed at meetings during the design of the interlaboratory study. During the development of the micro distillation method, both ASTM and EI had drafted their own versions which were harmonized, with both progressing through their separate balloting processes, with the intent that they would eventually be jointed. ASTM and EI have now developed a formal guideline for how this jointing process is to occur, which is the reason for this ballot. The guidelines outline that should the two organizations desire to work towards a joint standard or interlaboratory study than each organization should proceed through an approval process. For ASTM that requires a 2/3 approval of the subcommittee members, at a meeting or by letter ballot, and then approval of the committees executive subcommittee. Since this approval process is somewhat behind schedule, as the jointing agreement and development work had already been established prior to the new guidelines, it appears that the prudent course is to letter ballot the approval of the subcommittee now, for anticipated submission for approval of the executive subcommittee at the upcoming meeting in December 2009.
