Automotive fuels - Liquefied petroleum gas

11.8.2020.
A new fifth edition of the BiH standard BAS EN 589:2020, Automotive fuels - LPG - Requirements and test methods have been published. The standard is identical to the European standard EN 589: 2018, Automotive fuels - LPG - Requirements and test methods and was adopted by the translation method.
 
This standard 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.
 
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. 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 version are:
 
  • Reduction of the sulfur limit value to 30 mg/kg;
  • Removal of ASTM D 3246, sulfur determination by oxidative microculometry, as being incapable of measuring that level;
  • Addition of single limit value for propane in Table 1;
  • Addition of a single limit value for 1.3 butadiene in Table 1;
  • introduction of a test method for the determination of 1,3 butadiene and hydrocarbon composition, for the determination of low sulfur levels in LPG and to determine evaporation residue;
  • Addition of Clause 7 “Remarks concerning vehicle application issues like residues in vaporizers or injectors”;
  • Permission to use alternative odour test added to sub-clause 6.3;
  • Inclusion of reference to EN 16942 regarding pump marking.
 
 
BAS EN 589: 2020 was adopted into the system of Bosnia and Herzegovina’s standardization through its Technical Committee BAS/TC 11 - Petroleum and petroleum products.
