The new sixth edition of the BiH standard BAS EN 589+A1:2023, Automotive fuels - LPG - Requirements and test methods, was published, which was adopted as a translation of the European standard EN 589:2018+A1:2022, Automotive fuels - LPG - Requirements and test methods, in a bilingual version in Serbian and English.

This standard specifies requirements and test methods for marketed and delivered liquefied petroleum gas (LPG). LPG is defined as a low pressure liquefied gas under 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.

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 standard involves the sampling, handling and testing of LPG. All procedures should be performed away from sources of sparks, Naked flames, unprotected electrical equipment, electrostatic hazards etc. are sources of ignition for LPG.

LPG is heavier than air and accumulates in cavities. There is a danger of suffocation when inhaling high concentrations of LPG.

The main technical changes compared to the previous edition are:

-   update of the revised test methods 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 May 1, 2022.
