What is BS EN 15079- Spark OES Analysis of Copper and Copper Alloys (S-OES) about?
BS EN 15079 is a safety standard on copper and copper alloys.
BS EN 15079 specifies a routine method for the analysis of copper and copper alloys by spark optical emission spectrometry (S-OES).
The method is applicable to all elements except copper commonly present in copper and copper alloys as impurities or minor or main constituents, which can be determined by S-OES.
Who is BS EN 15079- Spark OES Analysis of Copper and Copper Alloys (S-OES) for?
BS EN 15079 on analysis by spark optical emission spectrometry (S-OES) is relevant to:
- Manufacturers of copper alloys
- Manufacturers of optical emission spectrometer
- Testing authorities
- Corrosion engineers
- Metallurgical engineers
Why should you use BS EN 15079- Spark OES Analysis of Copper and Copper Alloys (S-OES)?
An optical emission spectrometer is a spectrometer with a spark source capable of measuring the intensities of the optical radiation emitted at specific wavelengths by the elements present in the material.
BS EN 15079 assists with the measurement of the intensity of the radiation, whose wavelength is characteristic of each element, generated by a spark result from the application of an electrical discharge between the sample, as one electrode, and an inert counter-electrode. Concentrations of elements are determined by relating the measured intensities of test samples to calibration curves prepared from reference materials.
Overall, BS EN 15079 is useful as it provides guidance on the calibration of the spectrometer which is carried out by using a series of certified reference materials that have the same or at least similar matrix and metallurgical structure as the samples to be analyzed, to calculate the calibration functions from which the analysis of test samples can be obtained.
