What is PD CEN/TR 10261- Iron and steel- Chemical composition about?
PD CEN/TR 10261 is a safety standard on iron and steel.
PD CEN/TR 10261 lists, under Clause 4, the European Standards which are currently available for the determination of the chemical composition of steels and cast irons.
In Clause 5, PD CEN/TR 10261 provides details on the range of applications and gives the principle of the method described in each standard.
Annex A gives a list of other European Standards and CEN Technical Reports applicable for the determination of the chemical composition of steels and cast irons.
Annex B gives a list of withdrawn euro norms, together with the corresponding replacement European Standards, if any.
Annex C shows graphical representations of the content ranges of the methods listed in PD CEN/TR 10261. Figure C.1 gives the content ranges of the referee methods, Figure C.2 gives the content ranges of the routine methods, and Figure C.3 represents the fields of application of all the methods described.
Annex D provides a trilingual key of the abbreviations used in the Figures given in Annex C.
Note: Three methods applicable for the analysis of some ferro-alloys are listed in Annex A.
Who is PD CEN/TR 10261- Iron and steel- Chemical composition for?
PD CEN/TR 10261 on determining the chemical composition of iron and steel is relevant to:
- Chemical engineers
- Iron and steel industries
- Manufacturers of stainless-steel alloys
- Manufacturers of spectrometer
- Testing authorities
Why should you use PD CEN/TR 10261- Iron and steel- Chemical composition?
Iron is easier to cast than steel due to its lower melting. Steel is an alloy, it’s a blend of both iron and carbon but usually is less than 2.5% carbon compounds.
PD CEN/TR 10261 assists in determining the chemical composition of iron and steel. The method described in PD CEN/TR 10261 uses a calibration based on a very close matrix matching of the calibration solutions to the sample and bracketing of the mass fractions between 0,95 to 1,05 of the approximate content of chromium in the sample to be analyzed. The content of all elements in the sample has, therefore, to be approximately known. If the contents are not known the sample must be analyzed by some semi-quantitative method. The advantage of this procedure is that all possible interferences from the matrix are compensated, which results in high accuracy. This is most important for spectral interferences, which can be severe in very highly alloyed matrixes. All possible interferences are kept at a minimum level. Therefore, it is essential that the spectrometer used meets the performance criteria specified in the method for the selected analytical lines.
Overall, PD CEN/TR 10261 is useful as it provides guidance on various types of methods for determining the chemical composition of iron and steel.
