ASTM D8322-20<\/h3>\n

Active Standard: Standard Test Method for Determination of Elements in Residual Fuels and Crude Oils by Microwave Plasma Atomic Emission Spectroscopy (MP-AES)<\/h4>\n
\n

ASTM D8322<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the determination of metals and other elements in residual fuel and crude oil by microwave plasma atomic emission spectroscopy (MP-AES). The specific elements within the scope of this method are V, Ni, Ca, Na, Al, Si, Zn, P, and S for residual fuel oil and Fe, V, Ni, Ca, Na, K, and S for crude oils.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> Method working range: high expected concentration limit = highest ILS sample mean low expected concentration limit = lowest ILS sample mean if:<\/p>\n

\n

(1)<\/i> lowest ILS sample mean \u2212 Rlowest ILS sample mean<\/span><\/sub> > 0; otherwise it is determined by solving for X<\/span> using the following equation:<\/p>\n

(2)<\/i> X<\/span> \u2212 RX<\/span><\/sub>= coarsest resolution, determined by 0.5*\u03c3r lowest ILS sample mean<\/span><\/sub><\/p>\n<\/p><\/div>\n

\n <\/div>\n<\/p><\/div>\n
\n

1.3<\/span> This test method uses soluble metals in organic solvents for calibration and does not purport to quantitatively determine insoluble particulates. Analytical results are particle size dependent, and particles larger than a few micrometers may cause results to appear low<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> Elements present at mass fractions above the upper limit of the calibration curves can be determined with additional appropriate dilutions. Elements shall be measured at the wavelengths presented in Table 1<\/span>.<\/p>\n

<\/div>\n<\/p><\/div>\n
\n

1.5<\/span> The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<\/p><\/div>\n

\n

1.6<\/span> 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.<\/i><\/p>\n<\/p><\/div>\n

\n

1.7<\/span> This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.<\/i><\/p>\n<\/p><\/div>\n
