ASTM D5600-09

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1.2 Elements for which this test method is applicable are listed in Table 1. Detection limits, sensitivity, and optimum ranges of
the metals will vary with the matrices and model of spectrometer.
1.3 This test method is applicable only to samples containing less than one mass % ash.
1.4 Elements present at concentrations above the upper limit of the working ranges can be determined with additional,
appropriate dilutions.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 gross sample—the original, uncrushed, representative portion taken from a shipment or lot of coke.
3.1.2 ICP-AES—Inductively Coupled Plasma—Atomic Emission Spectrometry.
3.1.3 petroleum coke—a solid, carbonaceous residue produced by thermal decomposition of heavy petroleum fractions and
cracked stocks.
4. Summary of Test Method
4.1 Atest sample of the petroleum coke is ashed at 700°C. The ash is fused with lithium borate. The melt is dissolved in dilute
hydrochloric acid (HCl), and the resultant solution is analyzed by inductively coupled plasma atomic emission spectrometry
(ICP-AES) using simultaneous, or sequential multielemental determination of elements. The solution is introduced to the ICP
instrument by free aspiration or by an optional peristaltic pump. The concentrations of the trace metals are then calculated by
comparing the emission intensities from the sample with the emission intensities of the standards used in calibration.
5. Significance and Use
5.1 The presence and concentration of various metallic elements in a petroleum coke are major factors in determining the
