Foreword
This document (CEN/TR 15367-1:2007) has been prepared by Technical Committee CEN/TC 19 “Gaseous
and liquid fuels”, the secretariat of which is held by NEN.
This document supersedes CEN/TR 15367:2006.
For further information on any updates, see the Introduction to this document.
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
This part of this standard describes the distribution of automotive fuels in general and diesel in specific detail.
For guidance concerning petrol distribution, part 2 is published to specifically address ethanol.
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 (effectively this document). Apart from some harmonization of wording no changes have been
incorporated.
The work on both documents has been carried out with support from Concawe.
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 document provides general guidance on diesel fuel housekeeping. It does not pre-empt national or local
regulations but addresses the issues of contamination by water or sediment that may occur in the supply
chain during manufacture, storage and/or transportation. It does not address contamination by other products
nor does it address possible contamination by water or sediment that may occur on board of vehicles,
however, an informative note on vehicle factors is presented in Annex A.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 590, Automotive fuels – Diesel – Requirements and test methods
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 useful 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 enter the product at various stages of the supply chain but only becomes an issue if it is present as
free water, which can be a contributory cause of corrosion and biological contamination. Entry points include:
a) as dissolved water during manufacturing; this may become free water further down the supply chain
depending on ambient conditions if the product is cooled so much that it reaches saturation point;
b) as free water due to ingress as a result of e.g. heavy rainfall or through cracks in equipment;
c) as water vapour (moist air) through vents followed by cooling/condensation on tank walls, including the
vehicle tanks;
As it is virtually impossible to stop water from entering the supply chain, proper water management is
essential.
4.2 Sediment
Sediment may consist of rust, dirt, dust, oxidation products and biological growth. These may form over a long
period of time.
5 Housekeeping guidelines
5.1 Elements of good housekeeping
5.1.1 Operations
Proper attention to detail during all operating activities from product manufacturing to final delivery is essential
to guarantee product quality. There should be operating procedures in place covering receipt, delivery,
sampling, inspection, testing, and tank draining. These procedures should be reviewed and updated as
required, when product quality changes are taking place as a result of new regulations or the introduction of
new fuel types.
It is essential that personnel involved at each link in the chain, both company employees and contractors are
properly trained so that they are aware of and understand the importance of applying existing operating
procedures.
If the use of chemicals is considered anywhere in the supply chain for housekeeping purposes (e.g. corrosion
protection or biological disinfection) the potential impact on fuel quality and performance should be
investigated thoroughly. Non-chemical solutions are generally preferred.
5.1.2 Hardware
Age and design of existing hardware along the supply chain vary widely and it is possible to control product
quality properly with differently engineered installations. Quality control, however, is much easier if hardware is
designed to facilitate good housekeeping as described in the following sections.
5.1.3 Maintenance
No matter how well designed an installation may be, if it is not inspected and properly maintained, equipment
faults will develop over time which may eventually affect the ability of the operator to maintain product quality
at the required level.
5.2 Detailed recommendations
5.2.1 General
Recommendations are split into four sections for refineries, terminals, filling stations and transportation, each
covering various elements. They represent current industry experience and are based predominantly on
handling hydrocarbon diesel fuels.
5.2.2 Refineries
5.2.2.1 Testing
All batches of diesel fuel should be visually assessed, should not contain free water and should be free from
visible sediment. When testing for visual appearance, the prevailing ambient temperature should be
considered. Alternative methods such as on-line haze meters may be used. The product must meet the water
content and total contamination requirements of EN 590.
When a sample is not visually acceptable, it should be analysed to quantify the problem. Analysis at this point
enables any issues to be resolved at the refinery and avoid the problem becoming more widespread.
Test records should be kept for a sufficient period to cover market needs.
Product imports should be tested using the same approach as recommended for terminals (see 5.2.3).
5.2.2.2 Sampling
Upper, middle and lower samples should be taken from fixed off-take storage tanks for visual assessment and
analysis. All three samples should be examined for visual appearance, including confirmation that the blend is
not layered. Composite samples may be used for the other routine specification tests.
No special requirements are specified with respect to settling time, after blending, before sampling. If product
samples do not satisfy the visual appearance, water content or sediment tests, allowing time for settling is one
measure that can be employed to bring the product on specification.
5.2.2.3 Operations
Although some storage tanks have floating off-take points, most have fixed off-takes so procedures to avoid
build-up of water bottoms are essential. Most storage tanks are flat bottom, though they can be cone-up or
cone-down. Procedures to control water build-up (regular water bottoms checks and facilities to drain off water
as required) should be established based on local experience with the particular tank configuration, fuel
production process and local climate. These procedures should ensure that water is not carried forward to the
next stage of the supply chain.
Diesel tanks should also be checked periodically for bacteriological infection and there should be a procedure
to deal with such contamination in case it is detected. Once established, biological growth can be difficult to
rectify – prevention is better than a cure and is best achieved by good water management.
5.2.2.4 Hardware requirements
New tanks should be designed to optimise water draw-off capability and be fitted with anti-swirl systems to
minimise mixing of tank bottoms during filling.
They should also have convenient facilities for taking three
