Delivering real business benefits across key segments


ISO 17020 is a standard that specifies an inspection body's competence and the objectivity and consistency of its inspection activities. Various bodies have developed ISO 17020 conformity assessment requirements to increase trust and consistency in their inspection activities.

ISO 17020 certification entails all actions taken by an inspection body, such as inspecting practices, procedures, and services to assess their conformity and reporting findings to the operation to foster trust in the organisations conducting the checks.

The initial categorisation of the inspection bodies took place in 1998 to enhance the inspection procedure. These categories were revised in 2012 and are as follows:

  • Type A: An impartial inspection agency that only conducts inspections (independent of the parties involved)
  • Type B: An inspection body that only performs inspections for the organisation that the inspection body is a part of
  • Type C: An organisation that performs both first-party and second-party inspections, or both, and that is identifiable but does not necessarily provide inspection services to its parent organisation, other parties, or both.


ISO 17020 has several advantages. Some of the ISO 17020 benefits are listed below:

  • Increases effectiveness of inspection processes
  • Increases level of drive, cooperation, and skill
  • Improves tool maintenance control
  • Increases trust in inspection data
  • Enhances credibility and recognition internationally
  • Advises on how to analyse data
  • Boosts customer trust in the quality of the results
  • Gives an edge over the competition
  • Helps gain market share
  • Strengthens confidentiality
  • Establishes your organisation among the top-quality inspection bodies in the global market


The ISO 17020 document of accreditation may be used as a prerequisite or screening document by any organisation desiring to perform inspections.

Some of the requirements of ISO 17020 are:

  • For the activities to run smoothly, inspecting bodies must recognise and meet the standard requirements.
  • Analysing the kind of examination that should be performed
  • Choosing the type of evaluation based on how closely the standard is met
  • Selecting knowledgeable and qualified individuals to carry out the inspection.
  • Appointing technical and management personnel to analyse the technical requirements and manage the management system.
  • Ensuring that the inspection report is thoroughly prepared and error-free.
  • Analysing or studying the report to make sure it complies with the standards

  • What is the ISO IEC 17020 standard for?

    The ISO/IEC 17020:2012 standard helps inspection bodies to be competent, impartial, and consistent in their inspection activities. It applies to all inspection stages and to inspection bodies of types A, B, or C as described in ISO/IEC 17020:2012.

  • What is the difference between ISO 17020 and 17025?

    The two standards share similar management system requirements based on ISO 9001. ISO 17025 requirements focus more on impartiality, independence, and confidentiality, while ISO 17020 requirements concern measurement uncertainty, traceability, and analytical validation.

  • Why is ISO 17020 so important?

    The implementation of ISO 17020 increases both customer and management confidence in results and reports, as well as market share. ISO 17020 certification gives inspection bodies a better reputation as top-notch inspection bodies in the international market, as well as global recognition and credibility.
