Aluminium and aluminium alloys - Chemical analysis - Inductively coupled plasma optical emission spectral analysis

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.
