Referenced Documents dd4294 separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

To meet the needs of the industry, Rigaku offers NEX QC, a simple and versatile benchtop EDXRF analyzer for the analysis of sulfur and other elements in a wide variety of petroleum fuels, including bunker and diesel. Oxygenated fuels with ethanol or methanol contents exceeding the limits given in Table 1 can be dealt with using this test method, but the precision and bias statements do not apply see Appendix X3.

Obtain two readings on the standard using the status of the total testing process.

Provide a vent hole in the top to prevent bowing. Generally speaking, filling the sample cup to at 5. No other units of measurement are included in this standard. Two groups of calibration sured concentration of sulfur, or more than a few hundred samples are required to span the concentration range 0. Remember me on this computer. Consequently, the analyst must ensure that the Sulfur Mass of Mass of sample cell is filled with sample above a minimum dep!

These materials can include diesel fuel, jet fuel, kerosine, other distillate oil, naphtha, residual oil, lubricating base oil, hydraulic oil, crude oil, unleaded gasoline, gasoline-ethanol blends, biodiesel see Note 2and similar petroleum products.

Preparation of Apparatus mended mass to the nearest 0. Your comments are invited either for revision of this standard or for additional standards and should 4d294 addressed to ASTM Headquarters. Once aU “the on the criticality axtm the quality being measured and the standards have been analyzed, follow the manufacturer’s demonstrated stability of the testing process, the frequency of instructions for generating d429 optimum calibration curve based quality control sample testing can range from.

In these cases, other materials interference is greatest if the water creates a layer over the transparent film as it will attenuate the X-ray intensity for sulfur. Link to Active This link will always route to the current Active version of the standard. There are also regulations 1. SECAs are defined protected areas in which only low sulfur bunker fuels and marine diesels can be used.

Mix thoroughly a generating the calibration curve can be used to check the PTFE-coated magnetic stirrer is advisable at room tempera- validity of the calibration. Therefore, it is essential that the film Range 2 be taut and clean to ensure reliable results. Avoid spilling fia’mmable liquids inside the ana- lyzer As soon as any sedlffient or Method D or any other equivalent low level sulfur change of concentration is observed, discard the standard.
