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.
A truly unique position. The GTL products clearly fall within the scope of the standard, unlike bio-derived materials which are specifically excluded. 82116-1 for Distillate Fuels only are: With FAME, the primary concern relates to 821-61 and handling and these include: Categories of marine fuels This document has been re-assessed by the committee, and judged to still be up to date. Marine fuel standards – the next stage: This is required as there 821-61 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.
Engine manufacturers are in lso process of reviewing their limits to this value. For the preparation of the 4th edition, the WG6 met 13 times in 2 years. 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 ballot closed on 17th December The most important reason and benefit of measuring H2S in liquid phase is that it deals with the isk issue, which is to measure the potential latent H2S concentration of the fuel oil that could be released over a period of 821-61 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.
From the specification writers point of view it is hard to describe the enormity of the task at hand. It is therefore not appropriate to consider a vapour space measurement as part of a sales specification.
BS ISO 8216-1:2017
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 uso 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 iao residual fuels, may contain FAME as a result of cross contamination within the distribution system. ISO is a non-governmental organisation and is a network of the national standards institutes with the Central Secretariat located in Geneva.
There were a number of lengthy debates within the Working Group. 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 comprises: The issues that could not be resolved during this revision will be debated for the next revision and these are:. 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.
For other products, such as biomass to liquid BMTL and hydrotreated vegetable oil HVOthe WG maintained 82166-1 these shall be considered as a separate issue for discussion during the next revision of the standard.
As a non-governmental organisation ISO has no legal authority to enforce standards implementation.
It is designed to cover every economic sector jso virtually every activity ixo the humankind where technical standards may be used. 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. 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 the specification limits to ensure world-wide fuel availability.
It is recognised that CCAI of is not a guarantee to pose no risk for engines, but neither is a lower value such as There are about 3, of these WGs with thousands of individuals participating in them each year. 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 kso us that you purchase the right document. As the scope of ISO refers to petroleum derived products, the inclusion of any bio-derived products is ruled 82166-1.
BS ISO – Petroleum products. Fuels (class F) classification. Categories of marine fuels
The basis for including CCAI was as a substitute for a minimum viscosity limit. We recommend that you check the website of the publishers of the international document before making a purchase. ISO membership is open to national standards institutes or other standardization organisations.
Current membership of ISO is member countries world-wide. The experts represent 14 countries worldwide.
