ISO 13385‑1 is the first part of an international multi-series standard that covers geometrical product specifications of callipers.
ISO 13385‑1 provides the most important design and metrological characteristics of callipers:
ISO 13385‑1 gives technical specifications such as related terms and definitions, design characteristics, metrological characteristics, determination of conformity to specifications and marking for the callipers.
ISO 13385‑1 on the design and metrological characteristics of callipers is relevant to:
Calliper is a measuring instrument that evaluates a dimensional quantity of an internal or external feature on the basis of opposing contact from the movement of a slider with a measuring jaw, moving relative to a measuring scale on a rigid beam and to a fixed jaw. ISO 13385‑1 influences the chain links F and G of the chain of standards on size and distance in the general GPS matrix.
ISO 13385‑1 assist the user with the metrological characteristics and associated maximum permissible error (MPE) values that apply to any indications permitted for use of the calliper as defined by the manufacturer and when used in accordance with the manufacturer’s recommendations.
ISO 13385‑1 is a geometrical product specification (GPS) standard and is to be regarded as a general GPS standard. It is a part of the ISO/GPS matrix model that gives an overview of the ISO/GPS system. It applies the fundamental rules and the default decision rules of ISO/GPS unless otherwise indicated.
Overall, ISO 13385‑1 is helpful as it provides guidance on the calibration of a calliper that includes the evaluation of the performance of the calliper within its measuring range.
BS EN ISO 13385‑1:2019 supersedes BS EN ISO 13385‑1:2011, which is withdrawn. The main changes compared to the previous edition are as follows:
