Liquid petroleum products - Petrol - Determination of low lead concentrations by atomic absorption spectrometry

Standardom se utvrđuje metoda za određivanje niskih koncentracija olova atomsko apsorpcionom spektrometrijom u opsegu od 2,5mg/L do 10,0 mg/L.

This document specifies an atomic absorption spectrometric test method for the determination of the lead content of petrol in the range 2,5 mg/l to 10,0 mg/l. This test method is independent of the lead alkyl type. NOTE 1 Annex A describes an alternative procedure but with a poorer precision for the determination of the lead content of petrol in the range 3,0 mg/l to 10,0 mg/l. This procedure is also independent of the lead alkyl type. NOTE 2 For the purposes of this document, the term "% (V/V)" is used to represent the volume fraction. WARNING - The use of this document may 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.
