For the preparation of the 4th edition, the WG6 met 13 times in 2 years.
BS ISO 8216-1:2017
Post your Comments on this Blog. The fourth 82216-1 of the marine fuels standard has delivered more significant changes than ever before and will give all stakeholders confidence in improved fuel quality for this and future generations.
In view of the difficulty of establishing a wording that fuel is free of ULO, the WG agreed that it should be expressed in terms of when a fuel does contain ULO and amend the wording in Table 2 as follows: The new combination of elements isp not trigger incorrect 826-1 of ULO. ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva.
As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. Studying ignition and iwo properties. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection.
With FAME, the primary concern relates to storage and handling and these include: The ISO standard specifically refers to petroleum derived products only, however WG6 agreed that Gas to Liquids GTL products fall within the scope of the Standard being paraffinic hydrocarbons produced from petroleum natural gas via synthesis gas using gas to liquids technology.
Categories of marine fuels”. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest ios of a document, including where it has not yet been provided through an international feed. Therefore enough time was allocated to make the required decisions.
8216-11 are factors that are beyond the control of the supplier of the fuel.
It is important to us that you purchase the right document. It is important to remember that ISO standards are voluntary.
ULO — Due to changes to lubricating oils formulations improved criteria for assessing the presence of ULO in marine fuels were included. Thus, it should be treated as contamination from the supply chain system. Acid number limits included Hydrogen sulphide H2S limits included Acid Number — the limits for Distillate fuels were adopted from the accepted industry’s guiding limit of 0. Engine manufacturers are in the process of reviewing their limits to this value.
For other products, such as biomass to liquid BMTL and hydrotreated vegetable oil HVOthe WG maintained that these shall be considered as a separate issue for discussion during the next revision of the standard.
The issues that could not be resolved during this revision will be debated for the next revision and these are:. While bio-derived fuels can be produced by other process methods there is no general experience with regard to their application in marine systems and hence this Standard does not address those issues.

Changes to both Distillate and Residual Fuels are: However some countries may wish to adopt ISO standards as part of their regulations or legislations, for which they serve as the technical basis.
As the scope 88216-1 ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled out. It is recognised that CCAI of is not a guarantee to pose no risk for engines, but neither is a lower value such izo The basis for including CCAI was as a substitute for a minimum viscosity limit.
Furthermore, while biodiesel has proven to be acceptable for use in automotive and truck engines, there are unknowns as to the potential effects of FAME products on the range of marine engines and other equipment i. Changes in ISO Additionally there are a variety of different sourced FAME products each with its own particular characteristics having implications in respect of storage, handling, treatment, engine operations and emissions.
WG6 aim is, whilst considering the ixo, health and environmental issues, to take 821-1 consideration both technical and commercial aspects impacting the marine industry and especially the impact of the specification limits to ensure world-wide fuel availability.
Another most important consideration is when a supplier delivers fuel to a customer, the supplier should measure the presence of H2S in the liquid phase of the fuel in order to provide an indication of the maximum amount of H2S that may emerge from the liquid phase during subsequent handling of the fuel.
The GTL products clearly fall within the scope of the standard, unlike bio-derived materials which are specifically excluded. Vapour phase measurements in ship’s tank head space are strongly influenced not only by the amount of H2S in the liquid phase but also by factors such as: Measurement of H2S, using Draeger tube in vapour phase, as per standard test method ASTM Dwhile totally appropriate as an occupational health protection measure, has its limitations. Current membership stands at 47 experts from all sides of the marine industry such as: Changes for Distillate Fuels only are: ISO membership is open to national standards institutes or other standardization organisations.
The ISO entitled “Classification of marine fuels” has been revised and now it comprises: The lubricity limit is based on the existing requirements for high speed automotive and heavy duty 82161 diesel engines, of wear scar diameter.
The ballot closed on 17th December Notwithstanding this, the Working Group acknowledges that whilst H2S should not be present in marine fuels, the current test methodology and the requirements for setting the specification limits cannot guarantee that H2S gas will not be released during the course of onboard storage and handling. Each country means one member.

For Distillate Fuels the test method’s precision is under development through the Energy Institute in London. Notify me of new comments on this article. The limits for Residual Fuels are set at max limit of 2. The ballot isoo on 19th May The new limit will ensure that the whole industry follows a precautionary practice.
