In ISO 8217, foreign substances such as used oil or chemical waste must not be
added to the fuel. This is because of the hazards to the crew, machines and the
environment. Tests that are done for unwanted substances as acids, solvents and
monomers with titrimetric, infrared and chromatographic methods, are recommended.
This is because of the damage these foreign substances can cause to fuel treatment,
fuel injection equipment, pistons, rings, liners, and exhaust valves and seats.
Turbocharger, exhaust system and boiler contamination can also occur because of
poor fuel quality.
The engine inlet fuel quality uses the latest ISO 8217:2010 specification. Bunkers that
comply with ISO 8217:2005 can be used until the latest ISO specification is fully
released. In such conditions, the higher values for carbon residue and vanadium can
be satisfactory.
It is very important that the fuel is fit for purpose in the related engine application.
