SIST EN ISO 10360-5:2020 PDF

Overview

EN ISO 10360-5:2020 (ISO 10360-5:2020) is a Geometrical Product Specifications (GPS) standard that defines acceptance and periodic reverification tests for coordinate measuring machines (CMMs) using contacting probing systems. It applies to CMMs with single- or multiple-stylus contacting probes (spherical or hemispherical stylus tips) operating in discrete-point and/or scanning measuring modes. The standard specifies test methods, data analysis and conformity criteria expressed as maximum permissible errors (MPEs).

Key topics and requirements

• Scope: Applicable to single-stylus, fixed multi-stylus (e.g., “star” styli), multiple-probe systems, articulating probes, stylus/probe changers, manual and automated CMMs, and systems with scanning probes. Not applicable to non-contact probing systems.
• Rated operating conditions: Environmental and operating conditions under which tests should be performed are defined to ensure repeatability.
• Measuring equipment: Requirements for test artefacts and measuring equipment (e.g., test spheres, styli specifications) are described.
• Test procedures:
  • Single-stylus probing test (discrete point)
  • Scanning mode test (continuous contact scanning)
  • Multi-stylus tests for fixed multi-probe and articulating probing systems, including data analysis for multi-stylus size error, form error and location error
• Data analysis and conformity: Test data are evaluated against MPEs; the standard acknowledges the practical impossibility of fully isolating probing system performance from CMM performance and therefore specifies combined-system MPEs.
• Annexes: Informative and normative annexes cover ring-gauge tests, pre-test probe checks, interpretation of multi-stylus results, MPE/limit specification methods, workpiece influences, and small-sphere test equipment.

Practical applications

• Acceptance testing for new CMM deliveries to verify performance against contractual MPEs.
• Periodic reverification and routine calibration to maintain measurement confidence and compliance.
• Procurement and specification: Use in technical specifications to define required CMM probing performance.
• Quality assurance in manufacturing, metrology labs and inspection services to validate discrete-point and scanning measurement capabilities.
• Troubleshooting multi-stylus or articulating probe systems by interpreting multi-stylus size, form and location errors.

Who uses this standard

• CMM manufacturers and integrators
• Metrology and calibration laboratories
• Quality and inspection engineers in aerospace, automotive, medical device and precision manufacturing
• Standards and compliance officers preparing acceptance criteria or maintenance schedules
