PD CEN/TR 17491:2020

This standard PD CEN/TR 17491:2020 Automotive fuels. Information on aniline, N-methyl aniline, N-ethyl aniline, N,N di-methyl aniline and secondary-butyl acetate when used as blending components in unleaded petrol is classified in these ICS categories:

• 75.160.20 Liquid fuels

This document is intended to inform about the potential technical consequences on engine parts and fuel systems when some types of chemical compounds are used as blending components in unleaded petrol. This document is not meant to intentionally limit market fuel development.

The chemical compounds addressed, specifically, in this document are:

• sec-butyl acetate (SBA) (CAS 105?46?4),

• aniline (CAS 62?53?3),

• N-methyl aniline (NMA) (CAS 100?61?8),

• N-ethyl aniline (NEA) (CAS 103?69?5), and

• N,N di-methyl aniline (DMA) (CAS 121?69?7).

Other chemical compounds are not addressed in this document, however, attention is drawn to EN 228, which requires that unleaded petrol be free from any adulterant or contaminant that can render the fuel unacceptable for use.
