6. The re-release (Feb 1999) with amendment No. 1, approved in September 1988 (IUS 1−89)

This standard specifies a method of determining the spectral impurities iridium, palladium, rhodium, gold, iron (at mass proportion of each from 0.01 to 0.10%) and lead (for the mass concentration of from 0.001 to 0.020%) in the silver-platinum alloys.

The method is based on the translation of alloy into the globule (liquid drop of melt) and measuring the intensity of the impurity lines in the arc spectrum. Quantification of the mass fraction of impurities is set by calibration with standard samples.

1. GENERAL REQUIREMENTS

1.1. General requirements for method of analysis according to GOST 22864.

1.2. The numerical value of the result of the analysis must end with the digit the same category, and permissible differences.

(Added, Rev. N 1).

2. APPARATUS, REAGENTS AND SOLUTIONS

Spectrograph medium dispersion.

Arc generator of alternating current.

The three-stage attenuator.

Microphotometer.

Standard samples of the enterprise.

Electrodes, carbon, made from coal spectrality, brand high purity-7.

The lathe table for sharpening carbon electrodes.

Photographic plates of the spectral type II sensitivity of 10−15 conventional units.

The developer and fixer.

Hydrochloric acid according to GOST 3118, diluted 1:1.

(Changed edition, Rev. N 1).

3. PREPARATION FOR ASSAY

Samples for analysis must be in the form of strips or chips. To remove surface contamination samples before taking the test portions are boiled in hydrochloric acid (1:1) for 2 min, then washed with water and dried.

The electrodes were applied to the spectral coals with a diameter of 6 mm. the Lower electrode is notched with millimeter recess in the end face, in which is placed the sample to be analyzed or of standard sample mass of 0.10 g. the Counter serves as a carbon rod, sharpened to a hemisphere or a truncated cone with ground diameter of 1.5−2 mm.

(Changed edition, Rev. N 1).

4. ANALYSIS

Spectra photographed at slit width of the spectrograph 0.025 mm, exposure 30, a current of 5 A through a three-stage attenuator. The distance between electrodes 2.5 mm is adjusted during the exposure on the intermediate diaphragm. The photographic plate is placed in the cassette, departing 4 cm from the right far edge of the cassette.

For each of the analyzed and the standard sample receive three parallel definitions.

Photographic plates are in the developer temperature of 18−20 °C for 6 min.

Shown photographic plate is then rinsed with water, fixed, washed in running water for 10 min, dried and photometric.

5. PROCESSING OF THE RESULTS

5.1. Wavelength of analytical spectral lines is given in the table.


The designated element	Wavelength of lines of the designated element, nm	Element comparison	The wavelength of the line item comparisons, nm
Palladium	342,12	Platinum	315,66
Iridium	313,33	The same	315,66
Rhodium	343,49	«	315,66
Gold	267,59	«	280,32
Iron	259,94	«	280,32
Lead	283,31	«

5.2. Determination of the mass fraction of the elements are by the method of «three standards» with the objective photoretrieval. The calibration graphs are built for each analyzed element. Y-axis delay value difference pucherani lines of the designated element, and the abscissa shows the values of the logarithm of mass fractions of standard samples.

With the help of calibration curve by the known values of the difference of pochernenija find the contents of the analyzed element in the sample.

5.3. The convergence of the method is characterized by the relative standard deviation of 0.15.

The final result of the analysis be the arithmetic mean of three parallel measurements under the condition of:

ГОСТ 12555.2-83 Сплавы серебряно-платиновые. Метод спектрального анализа (с Изменением N 1) ,

where ГОСТ 12555.2-83 Сплавы серебряно-платиновые. Метод спектрального анализа (с Изменением N 1) is the greatest result of the parallel measurements;

least the result of the parallel measurements;

— relative standard deviation describing repeatability of measurements;

ГОСТ 12555.2-83 Сплавы серебряно-платиновые. Метод спектрального анализа (с Изменением N 1) — the arithmetic mean calculated from parallel measurements (3).
