DANSK DSF/FPRCEN/TR 17491 PDF

This document is intended to draw attention to the potential technical consequences on engine parts and fuel systems when some types of chemical compounds are used as blending components in unleaded petrol. The chemical compounds addressed specifically in this document are: secondary- Butyl acetate, Aniline and its derivatives such N-Methyl Aniline, N-Ethyl Aniline and di-Metyl Aniline. Other chemical compounds are not addressed in this document, however attention is drawn to clause 5.4 of EN 228 which requires that unleaded petrol shall be free from any adulterant or contaminant that can render the fuel unacceptable for use. Thus when considering blending of other chemical compounds, care should be taken to ensure they are fit for use in order to comply with this requirement. This document does not address environmental and/or health related issues. These aspects are beyond the scope of CEN/TC19 activities.
