International Classification for Standards ICS is an international classification system for technical standards. It is recognised that CCAI of is not a guarantee to 8126-1 no risk for engines, but neither is a lower value such as ISO membership is open to national standards institutes or other standardization organisations.

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 issues that could not be resolved during this revision will be debated for the next revision and these are:. 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 82166-1 interpreted with due diligence and care as they are not related to the total H2S entrained in the fuel or cargo.

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 the distribution system. The ISO entitled “Classification of marine fuels” has been revised and now it comprises: For the preparation of the 4th edition, the WG6 met 13 times in 2 years.

821-1 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.

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.

ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva. Categories of marine fuels This document has been re-assessed by the committee, and judged to still be up to date.

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. It is therefore not appropriate to consider a vapour space measurement as part of 82161 sales specification. How much H2S emerge from the liquid phase and what isoo be the resulting vapour concentration on board the vessel will depend on many factors like temperature, movement and the ullage space.

Nonetheless, as an indication of ignition performance, CCAI has been added as in order to avoid fuels with uncharacteristic density-viscosity relationships. Notify me of new comments on this article.

The ISO standard specifically refers to petroleum derived products only, however WG6 agreed that Gas to 82166-1 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.

The most important reason and benefit of measuring H2S in liquid phase is that it deals with the key issue, which is lso 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 isoo the ship, rather than the measurement of variable equilibrium dynamics of the vapour phase.

The new limit will ensure that the whole industry follows a precautionary practice. Post your Comments on this Blog.

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 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.

Therefore enough time was allocated to make the required decisions. As a non-governmental organisation ISO has no legal authority to enforce standards implementation. However vapour space measurement are appropriate to verify operational conditions on board a ship for crew health protection. H2S – the new limit will only be applied from 1 Julywhich will allow the industry to gain global experience of the prevailing levels and with the new test method.

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.

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. Changes 821-1 Residual Fuels only are: A fuel shall be free from ULO.

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.
