Tool calibration

Tool calibration is an easy finding for an auditor, because it is quick to check and easy to get wrong. A torque wrench past its recall date is visible in seconds. So this category is about the tool calibration register a Part 145 shop keeps. It also covers what happens when a tool fails calibration. The posts start with which tools belong on the register and which do not. Then they move to recall intervals, and how you set and justify them. They also cover traceability to a recognized standard and what a calibration certificate has to show. Finally, they deal with filing, so you can produce a certificate on demand instead of hunting for it. Tool calibration also has an awkward half. A tool comes back out of tolerance, and the questions start. The posts work through how far back the impact assessment has to reach and which completed jobs need a second look. They also show how to keep an out-of-calibration tool away from live work in the first place. We write them from inside a working wheel and brake shop, for shops without a dedicated quality department.
