The lubricity limit is based on the existing requirements for high speed automotive and heavy duty industrial diesel engines, of wear scar diameter. WG6 aim is, whilst considering the safety, health and environmental issues, to take into consideration both technical and commercial aspects impacting the marine industry and especially the impact of 821-61 specification limits to ensure world-wide fuel availability.
Changes for Distillate Fuels only are: Perhaps we are moving in the direction of higher quality residual fuels suitable for use in the engine without the need to first clean it. With FAME, the primary concern relates to storage and handling and these include: 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.
In addition, today’s non-marine distillate fuels can contain a significant amount of bio-derived components, which might impact on the oxidation stability of the fuel. 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: As a non-governmental organisation ISO has no legal authority to enforce standards implementation.
It is recognised that CCAI of is not a guarantee to pose no risk for engines, but neither is a lower value such as Nonetheless, as an indication of ignition performance, CCAI has been added as in order to avoid fuels with uncharacteristic density-viscosity relationships.
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. Fuel containers – Portable – Plastics and metal You may be interested in this related standard Automotive biodiesel – Specification for manufacture and blending You may be interested in this related standard.

Notify me of new comments on this article. 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.
The ISO entitled “Classification of marine fuels” has been revised and now it 8216-11 From the specification writers point of view it is hard to describe the enormity of the task at hand.
Marine fuel standards – the next stage: However some countries may wish to adopt ISO standards as part of their regulations or legislations, for which they serve as the technical basis. Categories of marine fuels”. ISO membership is open to national standards institutes or other standardization organisations.
However, because of its potentially fatal nature, operators of fuel storage terminals have prevented H2S from entering the supply chain system. For the preparation of the 4th edition, the WG6 met 13 times in 2 years. The chemistry of residual fuels is probably the most complex of the oil barrel and some of the components of the final blend are rather resultants than controlled fractions.
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.
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. 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.
It is therefore is appropriate to consider ieo vapour space measurement as part of a sales specification. The ballot closed on 19th May Engine ixo are in the process of reviewing their limits to this value.
ISO – European Standards
Prior to this revision of ISOthere was no 82216-1 on the amount of H2S permissible in marine fuels. These are factors that are beyond the control of the supplier of the fuel.
Current membership of ISO is member countries world-wide. As the scope of ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled out. The technical work is carried isi through technical committees — abbreviated as TCs. The ISO standard specifically refers to petroleum jso 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.
As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues.
A fuel shall be considered to contain ULO when either one of the following conditions is met: Thus, it should be treated as contamination from the supply chain system. A truly unique position.
It is important to remember that ISO standards are voluntary. The head space gas distribution in the test method’s container is uniform in composition, however the gas distribution in the ship’s tank head space is not uniform in composition. Each country means one member.
Categories of marine fuels This document has been re-assessed by the committee, and judged to still be up to date. Jso issues that could not be resolved during this revision will be debated for the next revision and these are:.
ULO — Due to changes to lubricating oils formulations improved criteria for assessing the presence of ULO in marine fuels were included.
