The Australian Transport Safety Bureau recommends that the American Society for Testing and Materials review standard D910 - 97 in relation to the maximum permissible quantities of undesired compounds in Avgas, either individually or collectively.

Initial response

Response from: American Society for Testing and Materials
Action status: Closed - Accepted
Response text:

The letter contained three proposed recommendations to ASTM. These recommendations were discussed at the Subcommittee J meeting on December 6, 2000. Subcommittee J agreed to the following replies, which use the same numbers as the original ATSB letter.

ATSB recommended a review of D 910 in relation to the maximum permissible quantities of undesirable compounds in Avgas. [name supplied]'s comments on the report have touched on the difficulties of setting any limits on presently unknown materials. Furthermore, any quantitative limits have to be justified by technical reasons that include an assessment of the effects of the material on engine or aircraft performance. Subcommittee J already has been addressing this problem for jet fuels, but to obtain a consensus any solution has to meet the needs of both producers and users. Once a workable solution is found, there should be no difficulty in transferring it to D 910.

Based on the above response you can see that the ATSB recommendations are receiving serious consideration in ASTM and I expect Subcommittee J will keep you advised of progress. In that connection I would recommend that an ATSB representative become an official non-voting member of the Subcommittee, so that such an individual would automatically receive all issued documents.
