DIN EN 14726:2005 PDF

Scope: This European Standard gives guidance on the criteria and the fundamental operation procedure governing the spark optical emission spectral analysis (S-OES) of metal samples, beginning with sampling, through sample preparation to reporting the test, as well as the requirements of the whole spark source spectrometric procedure which shall be fulfilled with respect to: -- observance of the agreed precision and trueness [ISO 3534-1, ISO 5725-1] of the analytical results with refer- ence to the agreed sample or sample area; -- traceability of the analytical results to the international base units -- mass (kg) and amount of substance (mol); -- proof of agreement between the spark spectrometric result and the average composition of the supplied metal sample within the given uncertainty [ISO 3534-1] of the analytical result; -- comparability of the test results between different laboratories; -- as far as possible, a trouble-free operation of the spark, spectrometer. These guidelines refer to computer-controlled simultaneously measuring spectrometers for the analysis of solid samples.
