Our company is an ISO 17025 accredited calibration lab that covers many disciplines of calibration; e.g. electrical/electronic, physical/dimensional, RF/microwave, etc. in industrial settings including everything from nuke plants to oil refineries, NASA, the military, etc.; you name it. One area we are branching out into is biomedical equipment. We won't be calibrating the common equipment that touches the patients (like thermometers, blood pressure cuffs, EKG machines, ultrasound machines, defibrillators, etc.), but rather we'll be calibrating the equipment that is used to verify and certify the above equipment, such as patient simulators, temperature simulators, safety analyzers, ultrasound wattmeters, pacemaker analyzers, etc. What standards (other than 17025) would we have to comply to do the calibration of these devices?
