Accuracy Standards

ISO 230-1 and 2 Guide

Use ISO 230-1 and ISO 230-2 as a procurement filter for geometric accuracy, positioning accuracy, and repeatability claims.

Direct answer: ISO 230-1 covers geometric accuracy; ISO 230-2 covers positioning accuracy and repeatability.

How to Use These Standards

  • Use ISO 230-1 when you need geometric checks such as straightness, squareness, and axis relationship.
  • Use ISO 230-2 when you need axis positioning accuracy and repeatability data.
  • Require the test report, not only a brochure number, when tolerances affect the buying decision.

Equipment Selection Handoff

Use the equipment selection calculator to connect ISO accuracy requirements with work envelope, process fit, budget, and support constraints.

Use the ISO 230 reference table when you need a compact comparison of accuracy terms and test-report fields.
