European foreword
This document (EN 589:2018+A1:2022) has been prepared by Technical Committee CEN/TC 19
“Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”,
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 August 2022, and conflicting national standards shall
be withdrawn at the latest by August 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes !EN 589:2018".
This document includes Amendment 1 approved by CEN on 6 January 2022.
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
th
This is the 7 edition of EN 589. The main technical changes include:
a) reduction of the sulfur limit value to 30 mg/kg;
b) removal of ASTM D 3246, sulfur determination by oxidative microcoulometry, as being incapable of
measuring that level;
c) addition of single limit value for propane in Table 1;
d) addition of a single limit value for 1,3 butadiene in Table 1 due to CLP requirements [5];
e) !introduction of new test methods for the determination of 1,3 butadiene and hydrocarbon
composition (DIN 51619), of low levels of sulfur content (EN 17178) and of evaporation residue
(EN 16423)";
f) addition of Clause 7 “Remarks concerning vehicle application issues like residues in vaporizers or
injectors”;
g) permission to use alternative odour tests added to sub-clause 6.3. The odour test according to
Annex A is not a precise test method with any given precision. Odour is subjectively perceived, not
measured. For this reason it is hard to define a referee method;
h) inclusion of reference to EN 16942 regarding pump marking in line with the requirements set by
the new Directive 2014/94/EU [1].
!The following is a list of significant technical changes between this amendment
EN 589:2018/A1:2022 and the actual European Standard, EN 589:2018:
— update of revised test method standards;
— adjustment of vapour pressure reporting format to the format required by the test methods
EN ISO 8973 and Annex C;
— removal of the increase of the propane content by 2022-05-01;
— modification of the footnote to table g to Table 1 on the performance requirement."
Any feedback and questions on this document should be directed to the users’ national standards body.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
1 Scope
This document specifies requirements and test methods for marketed and delivered automotive
liquefied petroleum gas (LPG), with LPG defined as low pressure liquefied gas composed of one or more
light hydrocarbons which are assigned to UN 1011, 1075, 1965, 1969 or 1978 only and which consists
mainly of propane, propene, butane, butane isomers, butenes with traces of other hydrocarbon gases.
This standard 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. The national health and safety regulations
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 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.
