Information technology and data standards

Cover software, systems, interoperability, data security, and digital services.

Environmental and sustainability standards

Focus on environmental performance, emissions, climate, and sustainability.

Health, safety, and medical standards

Used across healthcare, laboratories, and safety-critical environments.

Manufacturing and engineering standards

Cover production, tolerances, materials, and industrial processes.

  • ISO 9001 – Quality management (manufacturing use)
  • ISO 2768 – General tolerances
  • ISO 286 – Geometrical product specifications
  • ISO 4287 – Surface texture
  • ISO 1101 – Geometric dimensioning and tolerancing
  • ISO 4063 – Welding and allied processes

How many ISO standards exist in total?

  • 24,000+ active ISO standards

Which ISO standards can you be certified to?

Only management system standards (such as ISO 9001, ISO 27001, ISO 14001) are designed for third-party certification.
