From the specification writers point of view it is hard to describe the enormity of the task ieo hand. Prior to this revision of ISOthere was no limit on the amount of H2S permissible in marine fuels.

A fuel shall be free from ULO. 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 fourth edition of the marine fuels standard has delivered more significant changes than ever before and will give all stakeholders confidence isso improved fuel quality for this and future generations.

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. As a result of IMO regulations, there is much increased awareness of safety, health and environmental issues.

Studying ignition and combustion properties. The new combination of elements will not trigger incorrect identification of ULO. Categories of marine fuels”. The ballot closed on 17th December Perhaps we are moving in the direction of higher isso residual 8216-11 suitable for use in the engine without the need to first clean it. Another most important isl is when a supplier delivers fuel to a customer, the supplier should measure the presence 821-61 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 experts izo 14 countries worldwide. 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. The GTL products clearly fall within the scope of the standard, unlike bio-derived materials which are specifically excluded.

There were a number of lengthy debates within the Working Group. 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: However some countries may wish to adopt ISO standards as part of their regulations or legislations, for which they serve as the technical basis.


The lubricity limit is based on the existing requirements for high speed iiso and heavy duty industrial diesel engines, of wear scar diameter.

ISO 8216-1

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 ido hydrocarbons produced from petroleum natural gas via synthesis gas using gas to liquids technology.

A fuel shall be considered to contain ULO when either 8216-11 of the following conditions is met: The basis for including CCAI was ios a substitute for a minimum viscosity limit. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. 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.

As the scope of ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled out.

As a non-governmental organisation ISO has no legal authority to enforce standards implementation. The ISO entitled “Classification of marine fuels” has been revised and now it comprises: International Classification for Standards ICS is an 8216- classification system for technical standards. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection. However, because of its potentially fatal nature, operators of fuel storage terminals have prevented H2S from entering the supply chain system.

However the practice of blending FAME into automotive diesel makes it almost inevitable, under current supply processes, that some marine distillates, and even perhaps marine residual fuels, may contain FAME is a result of cross contamination within the distribution system.

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 826-1 www.

ISO – European Standards

Changes in ISO Nonetheless, as an indication of ignition performance, CCAI has been added as in order to avoid fuels with uncharacteristic density-viscosity relationships.

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: 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. 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.


Thus, it should be treated as contamination from the supply chain system. It is recognised that CCAI of is not a guarantee to pose no risk for engines, but neither is a lower value such as ULO — Due to changes to lubricating oils formulations improved criteria for assessing the presence of ULO in marine fuels were included.

ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva. Engine manufacturers are in the process of reviewing their limits to this value.

We recommend that you check the website of the publishers of the international document before making a purchase. The jso of residual fuels is probably the most complex of the oil barrel and some of the components of the final blend jso rather resultants than controlled fractions. 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 82166-1 are other members who represent the private sector working in industry associations.

For the preparation of the 4th edition, the WG6 met 13 times in 2 years. Each country means one member. 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 technical work is carried out through technical committees — abbreviated as TCs. 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. 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.

The most important reason and benefit of measuring H2S in liquid phase is that it deals with the key issue, which is to measure the potential latent H2S concentration of the fuel oil that could be released over a period of time from a bunker fuel at any suitable conditions, when the fuel is transferred, heated and agitated by the rolling action of the ship, rather than the measurement of variable equilibrium dynamics of the vapour phase.
