My company is getting ready for ISO17025 accreditation as a calibration lab. We will be calibrating Ultrasonic thickness gauges as well as ultrasonic flaw detectors. Myself and another person are tasked with handling this process and I am more than confused with the measurement uncertainty portion of this.
Can anyone help with what is needed for an uncertainty budget for a digital ultrasonic thickness gauge?
I believe that the uncertainty of the cal blocks themselves, as well as the repeatability of the tech taking readings and the gauge resolution are the factors that I need to calculate individual and combined to come up with an uncertainty statement.
Can anyone help guide me with where to start and formulas or examples on how to actually do this?
Thanks in advance.
