BAS EN 589+A1:2014, Automotive fuels - LPG - Requirements and test methods (EN 589: 2008 + A1: 2012, Automotive fuels - LPG - Requirements and test methods)

The fourth edition of BAS EN 589 + A1: 2014 was published, identical with the European standard EN 589:2008 + A1:2012, Automotive fuels - LPG - Requirements and test methods.

The European standard EN 589: 2008 + A1: 2012 was prepared by the European 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 (Netherlands Standardization Institute).

This 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.

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 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.

Bosnia and Herzegovina standard EN 589 + A1: 2014 contains a National annex (NA), which defines the national requirements for:

• sampling,
• pump marking and
• defining the vapor pressure.

BAS EN 589 + A1: 2014 was prepared by the technical committee BAS/TC 11, Petroleum and petroleum products, and was published in the Bulletin 2014-3/4 of the Institute for Standardization of Bosnia and Herzegovina.
