Draft DIN EN ISO 22854 extends precision scope for multidimensional gasoline GC
The draft discusses ethanol precision and E20 gasoline guidance; replacement of the current standard is not yet final.
DIN published a draft revision of DIN EN ISO 22854 for multidimensional gas-chromatographic analysis of gasoline. The proposed European text revisits precision descriptions for components including ethanol and provides guidance relevant to E20 gasoline.
This is a draft rather than an effective replacement. Fuel laboratories should compare the published draft with their current method and check the final edition and implementation status before changing specifications.
