• Abstract:

  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 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 A.1, where this method is referred to.

Foreword
This document (EN 589:2008) has been prepared by Technical Committee CEN/TC 19 “Petroleum
products, lubricants and related products”, the secretariat of which is held by NEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2009, and conflicting national standards shall
be withdrawn at the latest by February 2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document supersedes EN 589:2004.
Differences between this document and EN 589:2004 include:
 introduction of two new test methods for residues replacing the formerly applied EN ISO 13757 [1],
 introduction of a revised specification of residue content,
 introduction of a new test method for free water detection,
 update of the values in Table C.1 in terms of the number of digits.
Next, the Technical Corrigendum on the 2004 edition on Table B.1, as published in 2005, has been
incorporated.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,

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 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.
