Erdgas - Bestimmung der Beschaffenheit von Erdgas als verdichteter Kraftstoff für Fahrzeuge (ISO 15403:2000)
Ziel dieser Internationalen Norm ist die Bereitstellung von Daten zur Beschaffenheit von Kraftstoff für Erdgasfahrzeuge (NGV), die Hersteller, Fahrzeugbetreiber, Tankstellenbetreiber und andere Beteiligte der Industrie für mit verdichtetem Erdgas angetriebene Fahrzeuge benötigen, um Geräte für diese Fahrzeuge erfolgreich zu entwickeln und zu betreiben.
Kraftstoff, der die Anforderungen dieser Internationalen Norm erfüllt, sollte:
a) den sicheren Betrieb des Fahrzeugs und damit verbundener Geräte für Kraftstoffversorgung und Instandhaltung gewährleisten;
b) das Kraftstoffsystem vor den schädlichen Einflüssen von Korrosion, Vergiftung sowie der Ablagerung von flüssigen und festen Stoffen schützen;
c) eine zufrieden stellende Leistung des Fahrzeugs unter allen klimatischen Bedingungen und Fahrerfordernissen gewährleisten.
Einige Aspekte dieser Iinternationalen Norm können ebenfalls für die Anwendung auf Erdgas in ortsfesten Verbrennungsmotoren zutreffen.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 15403 was prepared by Technical Committee ISO/TC 193, Natural gas.

Introduction
Natural gas has been used to some extent as a fuel for internal combustion engines in compressor stations, co-
generation systems, and vehicles of various types for many years now. However, the prerequisites for growth, i.e.
economic viability and fuel availability, were generally not satisfied. Now, with the natural gas industry well
established, supplying 20 % of the world's primary energy, and the need for alternative, low-emission fuels, the
situation has improved considerably. During the past decade, natural gas vehicles have become a viable option with
some one million units now in use around the world. Growth is continuing as many governments actively promote
this clean-burning fuel with its environmental benefits. Many fleet operators are converting their vehicles, and
vehicle manufacturers are developing and marketing dedicated natural gas equipment.
In the context of this standard, natural gas vehicles (NGVs) utilize compressed natural gas stored "on-board". The
pressure of the gas stored in multiple containers is up to a maximum 25 000 kPa. Although the pressure has to be
reduced before combustion, compression and storage gives NGVs an adequate range. While NGVs were initially
equipped with converted gasoline or diesel engines, high-performance, dedicated natural gas engines are now
being extensively developed and produced. Liquefied natural gas (LNG) may also be stored in the fuel tanks of
natural gas vehicles. This, however, will be the subject of a separate International Standard.
This International Standard for the quality designation of compressed natural gas is designed to stipulate the
international requirements placed on the natural gas used as a motor fuel. Engine and vehicle manufacturers must
know these requirements so they can develop high-performance equipment which runs on compressed natural gas.
A technical report giving detailed data on the gas compositions used in ISO 15403 has been drafted and is being
circulated as an addendum.
INTERNATIONAL STANDARD ISO 15403:2000(E)
Natural gas — Designation of the quality of natural gas for use as a
compressed fuel for vehicles
1 Scope
The aim of this International Standard is to provide manufacturers, vehicle operators, fuelling station operators and
others involved in the compressed-natural-gas vehicle industry with information on the fuel quality for natural gas
vehicles (NGVs) required to develop and operate compressed-natural-gas vehicle equipment successfully.
Fuel meeting the requirements of this International Standard should:
a) provide for the safe operation of the vehicle and associated equipment needed for its fuelling and maintenance;
b) protect the fuel system from the detrimental effects of corrosion, poisoning, and liquid or solid deposition;
c) provide satisfactory vehicle performance under any and all conditions of climate and driving demands.
Some aspects of this International Standard may also be applicable for the use of natural gas in stationary
combustion engines.
