scope:

This Standard provides the essential requirements for the specification, verification, and calibration of calipers, including vernier, dial, electronic digital, and specialty calipers. ISO 13385-1 provides for the international definition of the design and metrological characteristics of calipers important in the specification, manufacture, and purchase of calipers; however, ISO 13385-1 does not provide specification values, detailed test methods, or sufficient discussion of traceability and measurement uncertainty to ensure consistent practice in the calibration of calipers. This Standard is intended to complement, not contradict, ISO 13385-1. For the verification or calibration of calipers, this Standard provides sufficient detail such that the user does not require access to ISO 13385-1.
