20、led Copy, (c) BSI EN 15486:2007 (E) 4 1 Scope This document specifies an ultraviolet (UV) fluorescence test method for the determination of the sulfur content of ethanol from 5 mg/kg to 20 mg/kg. Other products may be analysed and higher sulfur contents may be determined according to this test metho
21、d, however, no precision data for products other than ethanol and for results outside the specified range have been established for this document. Halogens interfere with this detection technique at concentrations above approximately 3 500 mg/kg. NOTE For the purposes of this document, the terms “%
22、(m/m)” and “% (V/V)” are used to represent the mass fraction and the volume fraction of a material respectively. WARNING The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. I
23、t is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the application of this document.
