This document 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.

This test method does not detect sulfur compounds that do not vaporize under the conditions of the test.

NOTE 1 LPG is 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.

NOTE 2 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction, µ, and the volume fraction, φ.

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.
