Full title and description

Geometrical product specifications (GPS) — Dimensional measuring equipment — Part 2: Design and metrological characteristics of calliper depth gauges. This international standard specifies the principal design features and metrological characteristics for calliper depth gauges, including instruments with analogue indication (vernier or circular/dial) and with digital displays.

Abstract

ISO 13385-2:2020 defines the most important design and metrological characteristics for calliper depth gauges to ensure consistent performance, interoperability and reliable measurement results. It covers analogue (vernier and dial) and digital instruments, and references established metrology guidance where appropriate (e.g., uncertainty and vocabulary).

Scope

ISO 13385-2:2020 specifies the most important design and metrological characteristics of calliper depth gauges — both with analogue indication (vernier scale or circular/dial scale) and with digital indication (digital display). The scope is limited to characteristics that affect measurement performance, interchangeability and calibration/verification practice.

Key topics and requirements

• Fundamental design characteristics of calliper depth gauges (mechanical construction, depth rod/beam configuration and contact elements).
• Indication types and requirements: vernier, dial (circular scale), and digital displays (resolution, legibility and reset/zeroing behavior).
• Metrological characteristics: accuracy, repeatability, resolution, permissible deviations and influence quantities relevant to depth measurements.
• Calibration and verification considerations, including reference to uncertainty of measurement (GUM) and metrological vocabulary (VIM).
• Normative references and decision rules for acceptance/rejection of instruments in measurement practice.

Normative references and decision-rule guidance referenced in the standard include ISO/IEC Guide 98-3 (GUM), the International Vocabulary of Metrology (VIM) and ISO/TR 14253-6.

Typical use and users

Primary users are manufacturers and designers of calliper depth gauges, calibration and testing laboratories, quality and metrology engineers in manufacturing and inspection organizations, procurement/specification writers, and standards bodies that adopt or reference GPS requirements for dimensional measuring equipment. The standard supports procurement specifications, instrument design validation and calibration/verification procedures.

Related standards

ISO 13385-2 is part of the ISO 13385 series on dimensional measuring equipment.
