RE-CERTIFICATION TEST

RE-CERTIFICATION TEST

Where fuel can be positively identified by documentary evidence as belonging to a

particular batch covered by a related Refinery Certificate of Quality, then it is only

necessary to conduct such additional tests as are required to prove that fuel quality has

not changed. The results of such tests shall be compared with the results of the last

tests, as well as reviewed for compliance with the specification. These recertification

tests are:

1. appearance/colour
2. distillation;
3. flashpoint;
4. density/API gravity;
5.  freezing point;
6.  corrosion (copper);
7. existent gum;
8.  conductivity (to be carried out on bulk stock in storage, or immediately after taking a sample from storage tanks on fuels containing static dissipater additive);
9. MSEP;
10. Thermal Stability (JFTOT), when fuel:

              1) is received from a source (e.g. a marine vessel equipped with copper

                pipework in their cargo tanks) contrary to recommended practice; or

              2) has been static in storage for six (6) months

FAME unless FAME (Fatty Acid Methyl Ester) can be controlled to limit the exposure in Jet Fuel to less than 5 mg/kg in accordance with JIG Bulletin 75, then in markets and supply chains where FAME is present in multiproduct systems, FAME concentration shall be tested by an approved method, wherever Jet fuel has been transported in multi-product transport systems that also carry gas oil/deisel fuel or non-dedicated storage that may have contained gas oil/ diesel fuel.

·         Sample quantity of 4 litres (0.5 US gallons) minimum shall be taken, in an approved container
