Standard Test Method for Chlorine in Aromatics by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry
| 분야 | |
|---|---|
| 적용범위 | 1.1 This test method covers the determination of chlorine by monochromatic wavelength-dispersive X-ray fluorescence (MWDXRF) spectrometry in aromatic hydrocarbons, their derivatives, and related chemicals. 1.2 This test method is applicable to samples with chlorine concentrations to 10 mg/kg. Higher chlorine concentrations can be determined by quantitatively diluting the sample with a suitable solvent. The limit of detection (LOD) is 0.2 mg/kg and the limit of quantitation is 0.7 mg/kg. With careful analytical technique or the measurement of replicates, or both, this method can be used to successfully analyze concentrations below the LOD. Note 1: The maximum is the highest concentration from the interlaboratory study (ILS) and the LOD and LOQ were calculated from Performance Testing Program (PTP) data. See Table 3. 1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard information, see Section 9. 1.6 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. |
