This standard 22/30444828 DC BS EN 14242. Aluminium and aluminium alloys. Chemical analysis. Inductively coupled plasma optical emission spectral analysis is classified in these ICS categories:

• 77.120.10 Aluminium and aluminium alloys
• 77.040.30 Chemical analysis of metals

This European Standard describes detailed steps for dissolution and preparation of calibration solutions. The pre-ferred use is for certification and referee analysis. All instrumentation, including software used in the testing labo-ratories, are different an subject to change. Therefore, general criteria for calibration and measurement are speci-fied. This method has to be used with primary reference materials whose mass of substance have a significant smaller uncertainty as required of the repeatability of the testing procedure.
