Foreword
This revised standard adopts the American Society for Testing and Materials standard ASTMD2622.2007 "wavelength dispersive X-ray Fluorescence Spectrometry
The method of "petroleum product sulfur content.
This standard is based on ASTMD2622. redrafted 2007.
In order for China's national conditions, the use of this standard in ASTMD2622.2007 when modified. This standard ASTMD2622.
2007 technical differences are as follows.
--- This standard ASTMD2622.2007 reference standard part of our revised to reference the corresponding national standards and industry standards.
For ease of use, this standard also made the following editorial changes.
--- Repeatability and reproducibility of written expression according to our habits were modified.
This standard replaces GB/T 11140-1989 "Petroleum products - Determination of sulfur (X-ray spectroscopy)", GB/T 11140-1989 is
Referring to the use of ASTMD2622. 1982 enacted.
The main technical differences between standard compared with GB/T 11140-1989 as follows.
--- Name of this standard has been modified by the "petroleum products Determination of sulfur (X-ray spectroscopy)" was changed to "sulfur-containing petroleum products
Determination of the amount of wavelength dispersive X-ray fluorescence spectrometry ";
--- This standard extends the scope of application;
--- The standard measurement limit has been changed from 10mg/kg ~ 5.0% (mass fraction) to 3mg/kg ~ 4.6% (mass fraction);
--- The standard reference standard has increased;
--- The standard interference element has fluctuated;
--- The standard test procedure in Chapter 2θ angle different crystals have increased or decreased;
--- This standard adds meaning and purpose, interfering factors, quality control three chapters;
--- This standard GB/T 11140-1989 Methods of sampling, preparation and sample chapter amended as sample preparation, calibration chapter;
--- The standard precision has been modified;
--- This standard adds to Appendix A "precision instructions."
Appendix A of this standard is an informative annex.

Determination of sulfur content of petroleum products
Wavelength dispersive X-ray fluorescence spectrometry
1 Scope
1.1 standard specifies under single-phase and liquid at room temperature, was properly heated liquid or soluble in the hydrocarbon solvent oil and petroleum products
Determination of total sulfur content of the product. This standard applies to the determination of diesel, jet fuel, kerosene, other distillate oil, naphtha, residual oil, lubricating base
Base oil, hydraulic oil, crude oil, motor gasoline, gasohol and biodiesel.
1.2 with ASTMD6259 statistical procedure to calculate the combined measurement of the standard limit of 3mg/kg.
1.2.1 For a particular laboratory instruments, which depends on the instrument measurement limits and precision of X-ray tube power (low or high power
Rate), and the type of laboratory sample specific operation to this method.
1.3 For the sulfur content exceeds 4.6% (by mass) of the sample by dilution of the sample to the sulfur content of this standard applies
range. Error measurement results undiluted samples diluted sample measurement results will be mentioned in Chapter 14 than high.
1.4 Volatile samples (such as high vapor pressure gasoline or light hydrocarbons) as a selective loss of light components during the analysis, may not meet this standard
Accurate precision.
A basic assumption of 1.5 standard is a standard sample matrix material and sample to be tested so as to match or 12.2 as described in the matrix
Different substances. Hydrocarbon mass ratio of the difference between the standard sample and the sample or the presence of other elements or interfering substances (see Table 1), will be made
Into a matrix does not match the material.
1.6 This standard uses SI SI units.
1.7 standard will be described only for some special risks associated with the testing process-related, but did not mention all the security issues. Accordingly, the user
Before using this standard to establish appropriate safety and health practices and to develop appropriate management system.

3 Method Summary
The sample is placed in the X-ray beam, the determination of sulfur Kα line intensity 0.5373nm wavelength. The highest intensity is subtracted
Background intensity measured at (rhodium anode X-ray tube 0.5437nm) recommended wavelength 0.5190nm, as net count rate previously prepared
Given calibration curves were compared (see Chapter 12), thereby obtaining a quality score or milligrams per kilogram (mg/kg) sulfur content expressed.
