Full title and description

Geometrical product specifications (GPS) — Dimensional measuring equipment — Part 1: Design and metrological characteristics of callipers. This international standard specifies the principal design and metrological characteristics for callipers with analogue indication (vernier or circular/dial scale) and with digital indication (digital display), and gives requirements for documentation and marking of instruments intended for dimensional measurement.

Abstract

This document provides the most important design and metrological characteristics of callipers — covering analogue indications (vernier or circular/dial scales) and digital displays — and includes requirements for metrological performance, indication in product documentation/data sheets, proof of conformance and marking.

Scope

ISO 13385-1:2019 specifies the essential design and metrological characteristics for callipers used for dimensional measurements (external, internal, depth and step measurements) and applies to callipers with vernier, circular (dial) or digital displays. The standard sets out requirements for design features, metrological performance (including maximum permissible errors and reference conditions), data-sheet information and marking, together with guidance on tests and conformance.

Key topics and requirements

• Design characteristics: principal dimensions, jaw geometry, depth‑rod and auxiliary feature requirements, scale intervals and ergonomics for vernier, dial and digital callipers.
• Metrological characteristics: definition of measurement characteristics, maximum permissible errors (MPE), reference temperature and rated operating conditions, resolution limits and relationship between scale step and achievable MPE.
• Indication and documentation: required information in product documentation and data sheets (range, resolution, MPE, reference conditions, intended use).
• Tests and verification: recommended error tests, shift and partial‑contact tests, and procedures for demonstrating conformance with specified characteristics.
• Marking and traceability: marking requirements on the instrument and guidance on proof of conformance and calibration information to be supplied.

Typical use and users

Used by manufacturers, metrology laboratories, quality assurance and inspection personnel, toolmakers and procurement specialists to specify, verify and document the performance of callipers intended for dimensional measurement in industrial and laboratory environments. The standard is applied when selecting callipers for production inspection, incoming inspection and calibration services.

Related standards

ISO 13385 is a multi‑part series. ISO 13385-2 (Design and metrological characteristics of calliper depth gauges) is the companion part covering depth gauge variants (published 2020). ISO 13385-1:2019 supersedes ISO 13385-1:2011. The series is produced under ISO/TC 213 (Geometrical Product Specifications).
