ASTM D5600 Test Method for Trace Metals in Petroleum Coke by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES)
13. Report
13.1 Report concentration for each element as mg/kg (ppm) or mass % (1000 mg/kg (ppm) = 0.1 %).
14. Quality Control
14.1 Confirm the performance of the instrument or the test procedure by analyzing a QC sample (see 8.8).
14.2 When QC/quality assurance (QA) protocols are already established in the testing facility, these may be used when they confirm the reliability of the test result.
14.3 When there is no QC/QA protocol established in the testing facility, see guidance from Practice D6299.
15. Precision and Bias
15.1 The values in the following statements and Table 2 were determined using the computing routine described in ASTM RR:D02-1007.
15.1.1 Precision - The precision of this test method as determined by the statistical examination of interlaboratory test results appears in Table 2.
15.1.2 Repeatability - The difference between successive results obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, exceed the values in Table 2 only in one case in twenty.
15.1.3 Reproducibility - The difference between the two single and independent results obtained by different operators working in different laboratories on identical test material would, in the long run, exceed the values in Table 2 only in one case in twenty.
15.1.4 Bias - The bias for the procedure in Test Method D5600 for measuring the trace metals in petroleum coke cannot be determined since suitable reference materials are not available.
