Overview
SIST EN ISO 13102:2014 specifies the most important design and metrological characteristics of electronic digital-indicator gauges used within the framework of Geometrical Product Specifications (GPS) for dimensional measurement. Developed by the European Committee for Standardization (CEN) and adopted from ISO 13102:2012, this standard ensures interoperable and reliable measuring equipment across global industries. The guidance provided in SIST EN ISO 13102:2014 supports manufacturing, quality assurance, and calibration activities where digital-indicator gauges play a critical role in dimensional inspection.
Key Topics
-
Design Characteristics
SIST EN ISO 13102:2014 details key physical attributes for electronic digital-indicator gauges, including:
- General design and nomenclature (bezel, display, buttons, stem, plunger, contact element, data output)
- Main dimensions and requirements for interchangeability
- Display clarity (unit identification, sign indication)
- Functional requirements (error messaging, electronic interfaces, zero adjustment)
-
Metrological Characteristics
The standard defines performance and accuracy criteria such as:
- Hysteresis and repeatability of indication error
- Maximum permissible errors in both partial and total measuring ranges
- Measurement forces (minimum and maximum)
- Requirements for resolution and calibration procedures
-
Operational Suitability
- Environmental protection: Specifies marking for ingress protection (IP) according to IEC 60529 and electromagnetic immunity
- Contact element requirements: Interchangeability, material, and form suitability for varying measurement tasks
- Additional functions: Inclusion of features like value preset, counting direction, and value storage, as documented by the manufacturer
-
Compliance and Documentation
- Proving conformance using ISO 14253-1 and evaluation of uncertainty as per ISO 14253-2 and ISO/IEC Guide 98-3
- Permanent and legible marking on the gauge, including measuring range, resolution, and unique identification
Applications
SIST EN ISO 13102:2014 plays a significant role in the manufacturing sector and wherever dimensional measurement is critical, especially in:
- Industrial Metrology Laboratories: Guiding equipment specification, calibration, and use in traceable measurement processes.
- Manufacturing Quality Control: Assuring the accuracy and repeatability of measurements during in-process and final inspections.
- Instrument Procurement: Assisting technical and purchasing departments in selecting gauges that conform to international standards.
- Calibration Services: Ensuring gauges meet defined metrological performance requirements and are calibrated accordingly.
Using digital-indicator gauges compliant with SIST EN ISO 13102:2014 helps minimize measurement errors, increase consistency, and assure product conformity in precision engineering and production environments.
