Foreword
This document (CEN/TR 15367-2:2007) 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.
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 petrol in specific detail.
For guidance concerning diesel distribution, part 1 is published to specifically address biodiesel or FAME.

Introduction
During a meeting held in Oslo on June 1 2005 through June 3 2005, CEN/TC 19 decided to adopt the
Preliminary Work Item "Fuels supply chain - Housekeeping guide for gasoline" on its Work Programme with
the intention to start an enquiry on this CEN Technical Report in 2006. It was later decided to link this work
directly with the already existing housekeeping guidelines for diesel fuel. 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.
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 be defined using a Total Quality
Assurance methodology.

1 Scope
This document provides general guidance on petrol fuel housekeeping. It does not pre-empt national or local
regulations. It 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 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 228, Automotive fuels – Petrol – Requirements and test methods
prEN 15376, Automotive fuels - Ethanol as a blending component for petrol - Requirements and test methods
3 Supply chain definition
For the purposes of this document the supply chain consists 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.
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. 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) 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 which may 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, each covering various elements for refineries, terminals, filling
stations and transportation. They represent current industry experience and are based on predominantly
handling hydrocarbon petrol fuels. Special requirements may be necessary for bio-fuels later described in this
document.
5.2.2 Refineries
5.2.2.1 Testing
All batches of petrol 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
appearance requirements of EN 228.
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 and regulatory requirements.
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 unless otherwise
specified in their respective test methods.
No special requirements are specified with respect to settling time, after blending and before sampling. If
product samples do not satisfy the visual appearance requirements, allowing time for settling is one measure
that can be employed to bring the product on specification.
5.2.2.3 Operations
Most petrol storage tanks have external floating roofs and fixed off-takes, so it is not unusual for small
volumes of water to leak into the stored petrol as a result of rainfall. Procedures to avoid build-up of water
bottoms are essential. The floating roof drain pipe typically passes through the main tank volume and it is
important to ensure that it does not leak into the petrol. Most storage tan
