Reference
a. 1 mm²/s = 1 cSt.
b. Notwithstanding the limits given, the purchaser shall define the maximum sulfur content in accordance with relevant statutory limitations. See Annex C.
c. Due to reasons stated in Annex D, the implementation date for compliance with the limit shall be 1 July 2012. Until such time, the specified value is given for guidance. For distillate fuels the precision data are currently being developed.
d. Purchasers should ensure that this pour point is suitable for the equipment on board, especially if the ship operates in cold climates.
e. If the sample is not clear and bright, the total sediment by hot filtration and water tests shall be required, see 7.4 and 7.6.
f. If the sample is not clear and bright, the test cannot be undertaken and hence the oxidation stability limit shall not apply.
g. If the sample is not clear and bright, the test cannot be undertaken and hence the lubricity limit shall not apply.
h. This requirement is applicable to fuels with a sulfur content below 500 mg/kg (0,050 mass %).
j. If the sample is dyed and not transparent, then the water limit and test method as given in 7.6 shall apply.
