This European Standard specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of liquefied petroleum gases (LPG) containing up to 0,35 % (m/m) halogens, and having sulfur contents in the range of 2 mg/kg to 50 mg/kg. Other products can be analysed for total sulfur content per this test method; however, no precision data for products other than liquefied petroleum gases and for sulfur content levels outside the specified range have been established for this test method. This test method may not detect sulfur compounds that do not vaporize under the conditions of the test. NOTE For the purposes of this document, the terms "% (m/m)"and "% (V/V)"are used to represent respectively the mass fraction and the volume fraction. WARNING - The use of this Standard can involve hazardous materials, operations and equipment. This Standard does not purport to address all the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to the application of the standard, and fulfil statutory and regulatory requirements for this purpose.

This European Standard specifies requirements and test methods for marketed and delivered automotive liquefied petroleum gas (LPG). 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 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. 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.
