The purchaser must specify the maximum sulphur content in accordance with the usual
statutory specifications.
3
The hydrogen sulphide limit is applicable from 1 July 2012.
4
If the sample is not clear and bright, it is necessary to do the total sediment by hot filtration
and the water tests.
5
If the sample is not clear and bright, you cannot do this test. Thus it is not possible to see
the compliance with the limit.
6
Purchasers must make sure that the pour point is sufficient for the equipment on board,
specially for operation in cold climates.
7
This parameter is applicable to fuels with a sulphur content of less than 0.05 mass %.
