This European Standard specifies a method for the determination of the lead content of gasolines with a lead concentration from 4 mg/l to 25 mg/l.NOTEFor the purpose of this European Standard, the term "% (V/V)" is used to represent the volume fraction.WARNING: The use of this European Standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
