Foreword
This document EN 589:2004 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 July 2004, and conflicting national standards shall be
withdrawn at the latest by July 2004.
This document supersedes EN 589:2000 in whole. In this fourth edition of EN 589 all relevant
characteristics, requirements and test methods are specified. Significant technical changes between
this European Standard and the previous edition are on:
- requirement of sulfur content
- test method for sulfur
- test method for vapour pressure, including introduction of an additional seasonal grade (E)
- requirement for methanol
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia,
Spain, Sweden, Switzerland and United Kingdom.
In this standard Annex A, B and C are normative, Annex D is informative.
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.
