TS EN ISO/IEC 17020/T1

TS EN ISO/IEC 17020/T1 is a technical document focused on the general competence and impartiality framework for bodies performing inspection across different sectors. The structure, resources, and degree of independence of an inspection body are central to the credibility of its findings, and this standard addresses those two aspects.

Competence and impartiality in inspection bodies

Inspection is the examination of a product, process, installation, or service against specified requirements. In this field, competence is associated with qualified personnel, suitable methods, orderly records, and consistent decision-making. Impartiality means controlling conflicts of interest and ensuring that inspection outcomes are not influenced by commercial or organisational pressures. This standard sets out general criteria for these principles irrespective of the sector involved.

Why inspection matters in the conformity assessment chain

In general technical terms, inspection is a key part of conformity assessment alongside testing, certification, and auditing activities. The reliability of an inspection body depends not only on technical capability, but also on organisational structure, clearly defined responsibilities, and the balance between confidentiality and impartiality. For that reason, the ISO/IEC 17020 family provides a common framework and vocabulary for different kinds of inspection activities.

• Provides general criteria regardless of sector.
• Addresses the competence of impartial inspection bodies.
• Defines the independence/impartiality framework at a technical level.
• Helps users understand the organisational expectations behind inspection services.
