Calibration is the process that ensures that the measurements obtained by a measuring tool are within allowable specifications and tolerances. These calipers are calibrated by measuring a reference standard, like a gage block. Traceability, an essential part of the calibration process, allows the reference standard used to calibrate a precision measuring tool to be traced directly back to the international definition of length. This assures that all measurements are calibrated using the same international standard. Calibrated calipers are exactly the same as their non-calibrated counterparts, but they include a traceable certificate of calibration.
how often do calipers have to be calibrated & why?
The most important purpose of the calibration of a caliper is to verify conformance with stated accuracy specifications in accordance with the ASME B89.1.14 standard. Calipers should be calibrated annually; however, as new products stored in our warehouse, the first ‘annual’ calibration is not required until one year after purchase—not a year after its original calibration date. If your business requires calibration records, simply attach the invoice showing date of purchase to your certificate of calibration, which will indicate the ‘clock starts ticking’ on calibration from purchase date, not calibration date.
