There are about 3, of these WGs with thousands of individuals participating in them each year. A fuel shall be free from ULO. Engine manufacturers are in the process of reviewing their limits to this value. 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.

The issues that could not be resolved during this revision will be debated for the next revision and these are:. Achieving universal agreement on contentious issues connected with today’s marine fuels is a good achievement, which was not easy. As a non-governmental organisation ISO has no legal authority to enforce standards implementation.

For Distillate Fuels the test method’s precision is under development through the Energy Institute in London. The technical 8216- is carried out through technical committees — abbreviated as TCs.

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.

From the specification writers point of view it is hard to describe the enormity of the task at hand. Changes in ISO 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 head space gas distribution in the test method’s container is uniform in composition, however the gas distribution in the ship’s tank ieo space is not uniform in composition. Therefore enough time was allocated to make the required decisions.


In addition, today’s non-marine distillate fuels can sio a significant amount of bio-derived components, which might impact on the oxidation stability of the fuel.

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.

Prior to this revision of ISOthere iiso no limit on the amount of H2S permissible in marine fuels. International Classification for Standards ICS is an international classification system for technical standards.

It is therefore not appropriate to consider a vapour space measurement as part of a sales specification. We recommend that you check the website of the publishers of the international document before making a purchase.

Post your Comments on this Blog. Changes to both Distillate and Residual Fuels are: Thus, it should be treated as contamination from the supply chain 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 website www. Follow 8216–1 links to find other Standards similar to the one you are viewing.

The limits for Residual Fuels are set at max limit of 2. 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. 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 standard.

It is important to remember that ISO standards are voluntary. The experts represent 14 countries worldwide. ISO membership is open to national standards ieo or other standardization organisations.

With FAME, the primary concern relates isk storage and handling and these include: However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection. 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.


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. Each country means one member.

For the preparation of the 4th edition, the WG6 met 13 times in 2 years. The lubricity limit is based on the existing requirements for high speed automotive and heavy duty industrial diesel engines, of wear scar diameter. 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.

The new 82166-1 of elements will not trigger incorrect identification of ULO. ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva.

A fuel shall be considered to contain ULO when either one of the following conditions is met: Additionally there iiso 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.

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 as a result of cross contamination within 82166-1 distribution 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. The fourth edition 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.

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: Categories of marine fuels”.
