ISO/TC 28/SC 4/WG 6 - Classification and specification of marine fuels

This document addresses quality considerations that apply to marine fuels in view of the implementation of maximum 0,50 mass % S in 2020 and the range of marine fuels that will be placed on the market in response to the international statutory requirements to reduce exhaust gas emissions. It defines general requirements that apply to all 0,50 mass % sulfur (S) fuels and confirms the applicability of ISO 8217 for those fuels. It gives technical considerations which might apply to particular fuels for the following characteristics: — kinematic viscosity; — cold flow properties; — stability; — ignition characteristics; — catalyst fines. Additionally, it provides considerations on the compatibility between fuels and additional information on ISO 8217:2017, Annex B (see Annexes B and D). NOTE 1 For the purposes of this document, 0,50 mass % S fuels refers to distillate and residual fuels with a sulfur content up to 0,50 mass %. NOTE 2 For the purposes of this document, "mass %" and "volume %" are used to represent the mass and volume fractions respectively. NOTE 3 This document can also be used in conjunction with earlier editions of ISO 8217 in the event an earlier edition is referenced in the commercial agreement between parties.

ISO 8217:2017 specifies the requirements for fuels for use in marine diesel engines and boilers, prior to conventional onboard treatment (settling, centrifuging, filtration) before use. The specifications for fuels in this document can also be applied to fuels used in stationary diesel engines of the same or similar type as those used for marine purposes. ISO 8217:2017 specifies seven categories of distillate fuels, one of which is for diesel engines used for emergency purposes. It also specifies six categories of residual fuels. For the purposes of this document, the term "fuels" is currently used to include the following: - hydrocarbons from petroleum crude oil, oil sands and shale; - hydrocarbons from synthetic or renewable sources, similar in composition to petroleum distillate fuels; - blends of the above with a fatty acid methyl ester(s) (FAME) component where permitted. NOTE 1 Appropriate guidance about fuel treatment systems for diesel engines is published by the International Council on Combustion Engines (CIMAC)[5]. NOTE 2 Requirements for gas turbine fuels used in marine applications are specified in ISO 4261[6]. NOTE 3 For the purposes of this document, the terms "mass %" and "volume %" are used to represent the mass and volume fractions respectively.

ISO 8216-1:2017 defines the detailed classification of marine fuels within class F (petroleum fuels). It is intended to be read in conjunction with ISO 8216‑99.

ISO 8217:2012 specifies the requirements for petroleum fuels for use in marine diesel engines and boilers, prior to appropriate treatment before use. The specifications for fuels in ISO 8217:2012 can also be applicable to fuels for stationary diesel engines of the same or similar make and type as those used for marine purposes. ISO 8217:2012 specifies four categories of distillate fuel, one of which is for diesel engines for emergency purposes. It also specifies six categories of residual fuel.

This International Standard specifies the requirements for petroleum fuels for use in marine diesel engines and boilers, prior to appropriate treatment before use. The specifications for fuels in this International Standard can also be applicable to fuels for stationary diesel engines of the same or similar make and type as those used for marine purposes. This International Standard specifies four categories of distillate fuel, one of which is for diesel engines for emergency purposes. It also specifies six categories of residual fuel.

ISO 8216-1:2010 establishes the detailed classification of marine fuels within class F (petroleum fuels). It is intended to be read in conjunction with ISO 8216-99.

ISO 8217:2010 specifies the requirements for petroleum fuels for use in marine diesel engines and boilers, prior to appropriate treatment before use. The specifications for fuels in ISO 8217:2010 can also be applicable to fuels for stationary diesel engines of the same or similar make and type as those used for marine purposes. ISO 8217:2010 specifies four categories of distillate fuel, one of which is for diesel engines for emergency purposes. It also specifies six categories of residual fuel.

ISO 8217:2005 specifies the requirements for petroleum fuels for use in marine diesel engines and boilers, prior to appropriate treatment before use. ISO 8217:2005 specifies four categories of distillate fuel, one of which is for diesel engines for emergency purposes. It also specifies ten categories of residual fuel.

ISO 8216-1:2005 establishes the detailed classification of marine fuels within class F (Petroleum fuels). It is intended to be read in conjunction with ISO 8216-99. All fuels for marine applications may be used for many similar but differing purposes in ships. Many marine fuels, being based on crude oil residue, defy specific definition but nevertheless can be categorized within the scope of ISO 8216-1:2005.
