Foreword
This document (CEN/TR 15367-1:2014) has been prepared by Technical Committee CEN/TC 19 “Gaseous
and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the secretariat of
which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 15367-1:2007. The update primarily addresses quality issues that can be
associated with blends of diesel fuels and Fatty Acid Methyl Esters (FAME) and by low-level contaminants in
diesel fuel that can be picked up in supply and distribution systems. These low level contaminants, such as
sodium and other inorganic contaminants, have recently been implicated in the formation of internal diesel
injector deposits (IDID).
CEN/TR 15367 consists of the following parts, under the general title Petroleum products - Guidelines for
good housekeeping:
— Part 1: Automotive diesel fuels
— Part 2: Automotive petrol fuels
— Part 3: Prevention of cross-contamination
This part of this Technical Report describes the distribution of automotive fuels in general and diesel in
specific detail. Part 2 was subsequently published to provide guidance on petrol distribution and specifically to
address ethanol issues. Finally, Part 3 was published to provide additional guidance on preventing cross-
contamination of fuel products in common supply and distribution systems. For further information on the
relationship between and the history behind each of the parts, see the Introduction to this document.
Introduction
During its meeting held in Cannes on June 27 2003, WG 24 “Specification for Automotive diesel” decided that
a guidance document on good housekeeping could be instrumental in preventing potential motoring problems
caused by contamination in the supply chain. This was endorsed by CEN/TC 19 resolution 24.5 and resulted
in an effective publication of the first Technical Report in March 2006.
When a similar guideline for petrol was being drafted, it was decided to link these two. The best option was to
publish them as separate parts of the same CEN document, which is achieved by revising the original
CEN/TR 15367:2006 Petroleum products — Automotive Diesel Fuels — Guide for good housekeeping as
part 1. Apart from some harmonization of wording no changes have been incorporated.
Two additional reports have now been published in this series regarding Automotive Petrol Fuels (Part 2) and
the Prevention of Cross Contamination (Part 3).The work on these three documents has been carried out with
support from CONCAWE and other stakeholders.
Automotive fuel specifications generally apply at the point of delivery to the customer. To ensure the quality at
this point, the best practice is to make sure that the product meets specification when it is dispatched from the
refinery and to have systems in place to ensure that it cannot go off-specification on its way to the customer.
There will be more than one method or procedure to handle many of the potential contamination issues
throughout the distribution chain, thus the advice in this document outlines principles to apply, but does not
specify the precise detail of the methods to be adopted in all cases. Nevertheless, it is strongly recommended
that all the procedures or measures to be applied along the distribution chain should be defined using a Total
Quality Assurance methodology.
1 Scope
This Technical Report provides general guidance on diesel fuel housekeeping. It does not pre-empt national
or local regulations but addresses the issues of contamination by water, sediment, inorganic contaminants, or
microbial growth that may occur in the supply chain during manufacture, blending, storage and transportation.
It does not address contamination by other fuel products nor does it address possible contamination by water
or sediment that may occur on-board vehicles. An informative note on vehicle factors is presented in Annex A,
however.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

3 Supply chain definition
For the purposes of this document, the supply chain is considered to consist of the following four parts:
— refineries,
— terminals,
— filling stations (including retail and industrial customer sites), and
— transportation from refineries to terminals and from terminals to filling stations.
Information on additives beyond the supply chain is given in Annex B.
4 Potential sources of water and sediment in the supply chain
4.1 Water
Water may be picked up by the diesel fuel product at various stages of the supply chain and can be present
either as free water or as an emulsion with small droplets of water suspended in fuel. The presence of FAME
can increase fuel/water emulsions. The presence of free water can be a contributory cause of corrosion and
biological contamination. Entry points for water include:
a) dissolved or emulsified water can occur during diesel fuel or FAME manufacturing. Dissolved or
emulsified water can remain suspended in fuel or may separate and become free water further along the
supply chain depending on the composition of the fuel and storage conditions. Cooling of the fuel blend
can cause the dissolved water to coalesce and separate from the fuel;
b) free water can occur due to ingress or leaks as a result of, for example, heavy rainfall or through cracks
in equipment;
c) water vapour (humid air) can enter storage tanks through air vents followed by cooling or condensation
on tank walls or vehicle tanks;
Because it is virtually impossible to stop water from entering the supply chain, proper water management is
essential. Tank inspections should routinely look for free water at the bottom of storage tanks. Free water,
along with emulsified fuel, should be drained to ensure that the remaining fuel is clear and bright and free of
extraneous material.
4.2 Potential sources of sediment
Sediment may be due to inorganic or organic contaminants in the fuel. Inorganic contaminants can consist of
rust, dirt, dust, corrosion products, and trace materials retained from fuel and FAME production. Organic
contaminants can consist of oxidation products, biological growth, and trace materials from fuel and FAME
production. Sediments may form over a long period of time under storage conditions.
4.3 Potential sources of biological contamination
Biological contamination can result from the action of microorganisms, such as bacteria, fungi, and yeasts,
which are ubiquitous in the environment. Microbes can bloom whenever there is a source of water, air
(oxygen), and fuel (as food). The presence of FAME in fuel can encourage growth. As a result, biological
contamination is more common in diesel fuels containing FAME than in gasoline containing bio-products.
Biological contamination can lead to bio-derived films and sediments in storage tanks, pipelines, and filters,
potentially causing serious operational problems including filter-bl
