I'm implementing ISO 17025 in my laboratory. *** company. When I'm writing verification and calibration methods, I'm not able to distinguish the difference between intern and extern? When have I to do an intern calibration? When have I to sent my equipments for calibration to an extern laboratory?
The measuring apparatus has to be linked to the SI system, so if my analyzer is calibrated by an accredited laboratory, I can virtually do all my calibration on my own?
