The CCAI limit included in the marine fuels standard is there to prevent abnormal or peculiar fuel blends from finding their way into the market. Therefore the measurement of H2S in vapour phase of the test method’s container as a fuel quality parameter could provide a false expectation for safe use, often providing lower than expected results, Such results must be interpreted with due diligence and care as they are not related to the total H2S entrained in the fuel or cargo.

ISO membership is open to national standards institutes or other standardization organisations. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. A fuel shall be free from ULO. The experts represent 14 countries worldwide.

Categories of marine fuels This document has been re-assessed by the committee, and judged to still be up to date. It is important to us that you purchase the right document. Ieo recommend that you check the website of the publishers of the international document before making a purchase. The lubricity limit is based on the existing requirements for high speed automotive and heavy duty industrial diesel engines, of wear scar diameter. There were a number of lengthy debates within the Working Group.

WG6 is perfectly aware that an unrealistic specification will not serve the industry well. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection.

This is required as there is no known generalised experience in respect of storage, handling, treatment and service performance including overboard discharges of biodiesel within the broad spectrum of the marine environment. 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.

It is recognised that CCAI of is not a guarantee to pose no risk for engines, but neither is a lower value such as ISO is a non-governmental organisation and is a network of the national standards institutes with the 2816-1 Secretariat located in Geneva.


The experiences gained with operation on low sulphur fuels, air quality, ship safety, engine performance, crew health as well as operational aspects and other changes of the bunker market realities were the main drivers for WG6 work and the agreed changes considered necessary were introduced into the 8216–1.

It is my pleasure to announce that the fourth edition of ISO — Specifications of marine fuels- and ISO — Classification of marine fuels- will be published on the 15th of June and available on the ISO website www. Each country means one member.

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 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.

These are factors that are beyond the control of the supplier of the fuel. The ballot closed on 19th May Changes to both Distillate and Residual Fuels are: Notify me of new comments on this article. Achieving universal agreement on contentious issues connected with today’s marine fuels is a good achievement, which was not easy. There are about 3, of these WGs with thousands of individuals participating in them each year.

However, because of its potentially fatal nature, operators of fuel storage terminals have prevented H2S from entering the supply chain system. Although the time frame of the development of the 4th edition might have looked tight, the WG6 took the necessary time to consider all issues.

Since the GTL products are paraffinic hydrocarbons and they are undistinguishable from the rest of the petroleum based marine fuel, no actual reference needs to be made for GTL synthesized hydrocarbons in the scope of the standard.

Notwithstanding this, the Working Group acknowledges that whilst H2S should not kso present in 82216-1 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.


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.

Changes in ISO As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues. Vapour phase measurements in ship’s tank head space are strongly influenced not only by the amount iiso H2S in the liquid phase but also by factors such as: Categories of marine fuels”.

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. 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.

ISO standards are normally revised every 5 years. 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.

It is important to remember that ISO standards are voluntary. Thus, it should be treated as contamination from the supply chain system. If you need help with the purchase or have any queries please email enquiries standards. ISO occupies a position between the private and public sectors, because some member institutes are part of the government structure in their countries but also there are other members who represent the private sector working in industry associations.

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. The new limit will ensure that the whole industry follows a precautionary practice. Prior to this revision of ISOthere was no limit on the amount of H2S permissible in marine fuels. Marine fuel standards – the next stage: Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.
