La présente partie de l'ISO 7627 spécifie la méthode à utiliser pour le dosage par spectrométrie d'absorption atomique dans la flamme du calcium, du potassium, du magnésium et du sodium dans les métaux-durs, à des teneurs en chacun de ces éléments comprises entre 0,001 et 0,02 % (m/m). Les prescriptions générales concernant le domaine d'application, le principe, les interférences, l'appareillage, l'échantillonnage et le procès-verbal d'essai figurent dans l'ISO 7627/1.
NOTE — La méthode de dosage de ces éléments est très critique aux faibles concentrations. On veillera avec soin à éviter toute pollution par l'atmosphère ou les réactifs utilisés.
