TS EN ISO/IEC 17020

TS EN ISO/IEC 17020 is a conformity assessment standard that sets out the general framework for the competence, impartiality and consistent operation of bodies performing inspection. Inspection means examining and evaluating a product, process, installation, plant or service against specified requirements. The standard addresses the organisational requirements that help an inspection body produce reliable and comparable outcomes.

Core technical ideas behind inspection bodies

Two issues are central in inspection work: technical competence and freedom from conflicts of interest. Competence means the inspection is carried out with suitable methods, qualified personnel and appropriate resources. Impartiality means decisions are protected from pressure, commercial influence or other undue interference. The focus of TS EN ISO/IEC 17020 is the combined assurance of these two elements and the ability of the body to manage inspection activities in a consistent and traceable way.

What the standard covers in practice

• Competence and impartiality arrangements for inspection bodies
• Organisational principles for consistent inspection activity
• Alignment of personnel, processes and resources with the inspection function
• A management approach that supports the reliability of inspection results

In the broader technical context, standards of this kind are widely used as a reference in accreditation and quality assurance. They are especially relevant where product checks, site inspections, equipment conformity checks and similar assessments are needed. The value of this standard lies not in prescribing each inspection technique, but in defining the common requirements that help an inspection body work in a reliable and consistent manner.
