Automotive fuels - LPG - Requirements and test methods
This European Standard specifies requirements and test methods for marketed and delivered automotive LPG (Liquefied Petroleum Gas). It is applicable to automotive LPG for use in LPG engine vehicles designed to run on automotive LPG.
NOTE: For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health which arises through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure is released large volumes of gas will be produced which form flammable mixtures with air over the range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling, handling and testing of LPG. All procedures should be conducted away from sources of ignition such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be performed as far as practicable under an electrically-safe ventilation hood.
LPG in the liquid form can cause cold burns to the skin. Protective clothing such as gloves and goggles should be worn if contact with the skin is likely to occur.
Unnecessary inhalation of LPG vapour should be avoided. The operator should not be exposed to atmospheres containing more than 1 800 mg/m3 over an 8 h time-weighted average (TWA) reference period, or more than 2 250 mg/m3 over a short term, 10 min reference period. One of the tests described in this European Standard involves the operator inhaling a mixture of air and LPG vapour. Particular attention is drawn to the cautionary statement provided in Annex A.1, where this method is referred to.
Kraftstoffe für Kraftfahrzeuge - Flüssiggas - Anforderungen und Prüfverfahren
Diese Europäische Norm legt die Anforderungen und Prüfverfahren fest für Flüssiggas für Kraftfahrzeuge (LPG, "Liquefied Petroleum Gas"), wie dieses in den Markt gebracht und an Endverbraucher abgegeben wird. Die Norm gilt für Flüssiggas zum Betrieb von Fahrzeugen, die für den Betrieb mit diesem Kraftstoff ausgerüstet sind.
ANMERKUNG Für den Zweck dieser Europäischen Norm wird das Symbol % (V/V) verwendet, um Volumenanteil in % auszudrücken.
WARNUNG - Der Umgang mit Flüssiggas macht wegen Brand und Explosionsgefahr besondere Vorsichtsmaßnahmen erforderlich. Das Einatmen des Gases in größeren Mengen ist gesundheits-schädlich.
Flüssiggas ist ein Gemisch leichtflüchtiger, flüssiger Kohlenwasserstoffe, das im Normalfall unter Druck gelagert wird. Druckentlastung führt zur Entstehung großer Gasvolumina, die in Mischung mit Luft im Konzentrationsbereich von 2 bis 10 % (V/V) explosiv sind. Diese Europäische Norm hat den Umgang, die Probenahme und die Prüfung von Flüssiggas zum Inhalt. Beim Umgang mit Flüssiggas sind Zündquellen wie offene Flammen, ungeschützte elektrische Einrichtungen und elektrostatische Gefahrenquellen aus dem Handhabungsbereich zu entfernen. Prüfungen von Flüssiggas sind nach Möglichkeit in einem ex-geschützten Abzug durchzuführen.
Im flüssigen Zustand kann Flüssiggas zu Erfrierungen der Haut führen. Schutzkleidung, wie Hand-schuhe und Schutzbrillen sollten getragen werden, wenn Hautkontakt nicht sicher ausgeschlossen werden kann.
Unnötiges Einatmen von Flüssiggas sollte vermieden werden. Im Umgang mit Flüssiggas sollten Personen keiner Atmosphäre ausgesetzt sein, die im 8 Stunden Mittel mehr als 1800 mg/m³ Flüssiggas enthält oder mehr als 2250 mg/m³ über eine Zeitspanne von 10 min. Die vorliegende Europäische Norm enthält ein Prüfverfahren, bei dem der Prüfende eine Mischung aus Luft und Flüssiggasdämpfen inhaliert. Die Sicherheitsmaßnahmen in Anhang A.1, der diese Prüfung behandelt, sind besonders zu beachten.
Carburant pour automobiles - GPL - Exigences et méthodes d'essai
La présente Norme européenne prescrit des exigences et des méthodes d'essai pour le carburant GPL (Gaz de Pétrole Liquéfié) mis sur le marché et livré. Elle est applicable au carburant GPL destiné aux véhicules conçus pour utiliser ce type de carburant.
NOTE Pour les besoins de la présente Norme européenne, la notation "% (V/V)" est utilisée pour représenter la fraction volumique.
AVERTISSEMENT - L'attention est particulièrement attirée sur les risques d'incendie ou d'explosion lors de la manipulation du GPL et sur les dangers que représenterait pour la santé l'inhalation de quantités excessives de GPL.
Les GPL sont des hydrocarbures liquides hautement volatils, normalement stockés sous pression. Si la pression est relâchée, la vaporisation de ces produits entraîne le dégagement de volumes appréciables de gaz capables de former avec l'air des mélanges explosifs dans les limites d'environ 2 % (V/V) à 10 % (V/V). La présente Norme européenne comprend l'échantillonnage, la manipulation et les essais sur le GPL. Il convient que toutes les opérations soient effectuées loin de toute source d'inflammation telle que flammes nues, équipements électriques non anti-déflagrants et risques électrostatiques. Il convient que les essais soient effectués dans la mesure du possible sous une hotte ventilée avec installation électrique anti-déflagrante.
Le GPL sous forme liquide peut provoquer des brûlures de la peau. Des équipements de protection tels que gants et lunettes de sécurité sont recommandés en cas de risque de contact avec la peau.
Il convient d'éviter toute inhalation inutile de vapeur de GPL. Il convient d'éviter que l'opérateur ne soit exposé à des atmosphères contenant plus de 1 800 mg/m3 sur une période de référence moyenne de 8 h (valeur moyenne d'exposition, VME) ou plus de 2 250 mg/m3 sur une période de référence de 10 min (valeur limite d'exposition, VLE). Un des essais décrits dans la présente Norme européenne oblige l'opérateur à inhaler un mélange d'air et

1 Scope
This European Standard specifies requirements and test methods for marketed and delivered automotive
LPG (Liquefied Petroleum Gas). It is applicable to automotive LPG for use in LPG engine vehicles designed
to run on automotive LPG.
NOTE: For the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard
to health which arises through inhalation of excessive amounts of LPG.
LPG is a highly volatile hydrocarbon liquid which is normally stored under pressure. If the pressure
is released large volumes of gas will be produced which form flammable mixtures with air over the
range of approximately 2 % (V/V) to 10 % (V/V). This European Standard involves the sampling,
handling and testing of LPG. All procedures should be conducted away from sources of ignition
such as naked flames, unprotected electrical equipment and electrostatic hazards. Testing should be
performed as far as practicable under an electrically-safe ventilation hood.
LPG in the liquid form can cause cold burns to the skin. Protective clothing such as gloves and
goggles should be worn if contact with the skin is likely to occur.
Unnecessary inhalation of LPG vapour should be avoided. The operator should not be exposed to
atmospheres containing more than 1 800 mg/m over an 8 h time-weighted average (TWA) reference
period, or more than 2 250 mg/m over a short term, 10 min reference period. One of the tests
described in this European Standard involves the operator inhaling a mixture of air and LPG vapour.
Particular attention is drawn to the cautionary statement provided in A.1, where this method is
referred to.

petroleum gas which can be stored and/or handled in the liquid phase under moderate conditions of
pressure and at ambient temperature, consisting predominantly of propane, butanes, with small
proportions of propene, butenes and pentanes/pentenes
4 Sampling
Samples shall be taken as described in EN ISO 4257 and/or in accordance with the requirements of national
standards or regulations for the sampling of automotive LPG. The national requirements shall be set out in
detail or shall be referred to by reference in a national annex to this European Standard.
In view of the sensitivity of some of the test methods referred to in this European Standard, particular attention
shall be paid to compliance with any guidance on sampling containers which is included in the test method
standard.
NOTE 1 It is important that the sampling procedure is followed in detail in order to avoid evaporation losses.
NOTE 2 Before sampling from the dispenser hose, 20 l of product should be pumped or recirculated, in order to
obtain a representative sample.
