(Test Method)Standard Test Methods for Determination of Aluminum and Silicon in Fuel Oils by Ashing, Fusion, Inductively Coupled Plasma Atomic Emission Spectrometry, and Atomic Absorption Spectrometry
Standard Test Methods for Determination of Aluminum and Silicon in Fuel Oils by Ashing, Fusion, Inductively Coupled Plasma Atomic Emission Spectrometry, and Atomic Absorption Spectrometry
SIGNIFICANCE AND USE
5.1 Catalyst fines in fuel oils can cause abnormal engine wear. These test methods provide a means of determining silicon and aluminum, the major constituents of the catalysts.
SCOPE
1.1 These test methods cover the determination of aluminum and silicon in fuel oils at concentrations between 5 and 150 mg/kg for aluminum and 10 and 250 mg/kg for silicon.
1.2 Test Method A—Inductively coupled plasma atomic emission spectrometry is used in this test method to quantitatively determine aluminum and silicon.
1.3 Test Method B—Flame atomic absorption spectrometry is used in this test method to quantitatively determine aluminum and silicon.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, 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. Specific warning statements are given in Sections 7.6, 10.1, and 11.5.
