1 Scope

This standard specifies the method for the determination of copper, lead, iron, strontium, barium, phosphorus and arsenic in brass by X-ray fluorescence spectrometry. This standard is applicable to the determination of copper, lead, iron, antimony, bismuth, phosphorus and arsenic in ordinary brass and arsenic-added ordinary brass. The measurement range is shown in Table 1. Table 1 Scope of application of the method element Content range Cu 54～97 Pb 0.01~0.6 Fe 0.01~0.5 Bi 0.001 to 0.008 Sb 0.003~0.12 P 0.005～0.06 As 0.01~0.12 Zn balance

3 Method summary

Measuring the X-ray fluorescence intensity of the characteristic line of the element to be tested in the sample, according to the relationship between the intensity of the X-ray fluorescence and the content of the element to be tested The relationship between the quantity and the regression method and the mathematical correction mode are used to calculate the content of the element to be tested.

4 instruments

Wavelength dispersive X-ray fluorescence spectrometer, in line with GB/T 16597 regulations.

5 Determination steps

5.1 Preparation of samples The sample is a block or plate sample, and the X-ray surface must be processed until the surface roughness is less than the maximum contour specified in GB/T 1031. Degree (R狔) 6.3 μm. The same method is used for the calibration sample and the sample to be tested. For example, the surface of the sample is processed by metallographic sandpaper grinding, and the same card is required. Number of sandpaper. The surface of the sample shall be measured immediately after processing. Note. The surface roughness of the sample can be obtained by fine car, finish milling, fine planing or metallographic sanding. The sample does not need to be polished. If you can use fine Grinding on the 120th metallographic sandpaper. ......
