At the December 2nd 2021 ASTM D02.J.01 Jet Fuel Specifications meeting delegates proposed adding a guidance Note to ASTM D1655 Table 1 for the testing of co-processed product. This was to highlight the more stringent requirements and approved methods detailed in Table A1.1 and avoid duplicate analysis where appropriate. A motion to progress this item was approved without opposition. The current ballot offers revised wording as Note N. Other Note references have been updated accordingly and re-aligned to the order of appearance in the table. A minor change for consistency is also required in Table A1.1 Note F and has been included.
