Automotive fuels - LPG - Requirements and test methods

This document specifies requirements and test methods for marketed and delivered automotive LPG (commonly known as low pressure gas or liquefied petroleum gas).
This document 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 terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
WARNING - Attention is drawn to the risk of fire and explosion when handling LPG and to the hazard to health arising 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. Naked flames, unprotected electrical equipment electrostatic hazards etc. are sources of ignition for LPG.
LPG in liquid form can cause cold burns to the skin. National health and safety regulations can apply.
LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.
CAUTION - One of the tests described in this document 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.

Kraftstoffe - Flüssiggas - Anforderungen und Prüfverfahren

Dieses Dokument legt Anforderungen und Prüfverfahren für gehandeltes und geliefertes Flüssiggas (en: LPG, allgemein bekannt als low pressure gas oder liquefied petroleum gas) für den Gebrauch in Kraftfahrzeugen, fest.
Dieses Dokument ist anwendbar für Flüssiggas für Kraftfahrzeuge, die auf den Betrieb mit diesem Kraftstoff ausgelegt sind.
ANMERKUNG   Für die Zwecke dieses Dokuments wird zur Angabe des Massenanteils μ einer Substanz der Ausdruck „% (m/m)“ und für den Volumenanteil φ einer Substanz der Ausdruck „% (V/V)“ verwendet.
WARNUNG — Der Umgang mit Flüssiggas ist mit Brand- und Explosionsrisiken verbunden. Das Einatmen von Flüssiggas in größeren Mengen ist gesundheitsschädlich.
Flüssiggas ist ein Gemisch leichtflüchtiger, flüssiger Kohlenwasserstoffe, das üblicherweise unter Druck gelagert wird. Druckentlastung führt zur Entstehung großer Gasvolumina, die in Mischung mit Luft im Konzentrationsbereich von etwa 2 % (V/V) bis 10 % (V/V) entflammbar sind. Dieses Dokument behandelt den Umgang, die Probenahme und die Prüfung von Flüssiggas. Offene Flammen, ungeschützte elektrische Einrichtungen, elektrostatische Gefahrenquellen usw. sind Zündquellen für Flüssiggas.
Im flüssigen Zustand kann Flüssiggas zu Erfrierungen der Haut führen. Es können nationale Arbeitsschutzvorschriften gelten.
Flüssiggas ist schwerer als Luft und sammelt sich in Vertiefungen an. Beim Einatmen hoher Konzentrationen von Flüssiggas besteht Erstickungsgefahr.
ACHTUNG — Eines der in diesem Dokument beschriebenen Prüfverfahren erfordert das Inhalieren einer Mischung aus Luft und Flüssiggasdämpfen durch die Prüfperson. Die Sicherheitsmaßnahmen in A.1, worin dieses Verfahren behandelt wird, müssen besonders beachtet werden.

Carburants pour automobiles - GPL - Exigences et méthodes d'essai

Le présent document spécifie des exigences et des méthodes d'essai pour le gaz de pétrole liquéfié (GPL) destiné aux véhicules commercialisés et livrés avec du GPL (communément appelé gaz liquéfié à basse pression ou gaz de pétrole liquéfié).
Ce document est applicable au carburant GPL destiné aux véhicules à moteur conçus pour utiliser ce type de carburant.
NOTE   Pour les besoins du présent document, les expressions « % (m/m) » et « % (V/V) » sont utilisées pour représenter respectivement les fractions massique, µ, et volumique, φ.
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 représente 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 la production de volumes conséquents de gaz capables de former avec l'air des mélanges explosifs dans les limites d'environ 2 % (V/V) à 10 % (V/V). Le présent document comprend l'échantillonnage, la manipulation et les essais sur le GPL. Les flammes nues, les équipements électriques non anti-déflagrants, les risques électrostatiques, etc sont des sources d’inflammation des GPL.
Le GPL sous forme liquide peut provoquer des brûlures de la peau. La réglementation nationale relative à la santé et à la sécurité peuvent s’appliquer.
Le GPL est plus dense que l’air et s’accumule dans les cavités. Il existe un risque de suffocation lorsque des concentrations élevées de GPL sont inhalées.
AVERTISSEMENT — L’un des tests décrits dans le présent document implique l’inhalation par l’opérateur d’un mélange d’air et de vapeurs de GPL. Une attention particulière est attirée sur la mise en garde fournie en A.1 de l’Annexe A, où cette méthode est définie.

Goriva za motorna vozila - Utekočinjeni naftni plin (UNP) - Zahteve in preskusne metode

Ta dokument določa zahteve in preskusne metode za prodajani in dobavljeni utekočinjeni naftni plin (LPG) za motorna vozila, pri čemer je utekočinjeni naftni plin opredeljen kot nizkotlačni utekočinjeni plin, sestavljen iz enega ali več lahkih ogljikovodikov, ki so dodeljeni samo k UN 1011, 1075, 1965, 1969 ali 1978 ter vsebujejo predvsem propan, propen, butan, izomere butana in butene s sledmi drugih plinastih ogljikovodikov.
Ta standard se uporablja za utekočinjeni naftni plin, namenjen za pogon vozil z motorjem na utekočinjeni naftni plin.
OPOMBA: V tem evropskem standardu sta uporabljeni oznaki »% (m/m)« in »% (V/V)«, ki predstavljata masni delež (µ) oziroma prostorninski delež (φ).
OPOZORILO: Pri ravnanju z utekočinjenim naftnim plinom je treba opozoriti na nevarnost požara in eksplozije ter na nevarnost za zdravje pri vdihavanju prevelikih količin utekočinjenega naftnega plina.
Utekočinjeni naftni plin je izjemno hlapna tekočina ogljikovodikov, ki se običajno shranjuje pod tlakom. Če se tlak sprosti, nastanejo velike količine plina, ki z zrakom tvorijo vnetljive mešanice v razponu približno od 2 % (V/V) do 10 % (V/V). Ta evropski standard vključuje vzorčenje in preskušanje utekočinjenega naftnega plina ter ravnanje z njim. Odprt plamen, nezaščitena električna oprema, nevarnost elektrostatike itd. so viri vžiga za utekočinjeni naftni plin.
Utekočinjeni naftni plin lahko povzroči ozebline. Veljajo nacionalni predpisi o varnosti in zdravju.
Utekočinjeni naftni plin je težji od zraka in se nabira v odprtinah. Obstaja nevarnost zadušitve pri vdihavanju visokih koncentracij utekočinjenega naftnega plina.
PREVIDNO: Eden od preskusov, opisanih v tem evropskem standardu, vključuje izvajalca, ki vdihava mešanico zraka in hlapov utekočinjenega naftnega plina. Posebna pozornost je namenjena opozorilu iz točke A.1, ki se sklicuje na to metodo.
