What Is Norma ISO 17020 2004?

Norma ISO 17020 2004, oﬃcially titled "Conformity assessment — Requirements for the

operation of various types of bodies performing inspection," is an international standard

developed by the International Organization for Standardization (ISO). Its primary purpose

is to specify the criteria that inspection bodies must meet to demonstrate their

competence, consistency, and impartiality in performing inspection services.

Unlike other ISO standards that focus on testing laboratories or certiﬁcation bodies, ISO

17020 speciﬁcally targets inspection bodies, which carry out activities such as product

inspections, process inspections, and even inspections related to safety and regulatory

compliance.

Types of Inspection Bodies Covered

The norma iso 17020 2004 recognizes three main types of inspection bodies based on

their organizational structure and relationships:

Type A: Independent inspection bodies with complete independence from other

activities that could aﬀect impartiality.

Type B: Inspection bodies that are part of an organization oﬀering other services

but maintain a degree of independence.

Type C: Inspection bodies that are part of an organization providing design,

manufacture, supply, installation, or maintenance services.

This classiﬁcation helps clarify the level of impartiality expected and the measures needed

to safeguard objectivity in inspection results.

Key Requirements of Norma ISO 17020 2004

Understanding the core requirements of norma iso 17020 2004 is essential for inspection

bodies aiming to obtain or maintain accreditation. These requirements collectively ensure

that inspections are carried out consistently, fairly, and competently.

Impartiality and Independence

One of the foundational principles of the norma iso 17020 2004 is the need for inspection

bodies to remain impartial. This means that inspection decisions must be free from

commercial, ﬁnancial, or other pressures that might inﬂuence the outcome. For example,

an inspection body should not be involved in designing or manufacturing the product it

inspects, especially if it could compromise impartiality.

Organizational arrangements, such as clear separation of functions and transparent

reporting lines, are often implemented to safeguard independence, particularly in Type B

and C inspection bodies.

Competence of Personnel

Competent personnel are the backbone of any credible inspection body. Norma ISO 17020

2004 requires that all personnel involved in inspection activities have the necessary

qualiﬁcations, training, experience, and skills.

Continuous professional development is emphasized, encouraging inspection bodies to

invest in ongoing training programs and competency evaluations. This ensures inspectors

stay up-to-date with evolving technical standards, regulatory requirements, and best

practices.

Inspection Procedures and Documentation

Standardized inspection procedures are vital to achieving consistent results. Norma ISO

17020 2004 mandates that inspection bodies develop, document, and implement clear

procedures covering every aspect of the inspection process—from planning and execution

to reporting and corrective actions.

A well-maintained documentation system also supports traceability, enabling inspection

bodies to demonstrate how inspections were conducted and decisions made. This

transparency is critical for building trust with clients and regulatory authorities.

Equipment and Calibration

The accuracy and reliability of inspection results depend heavily on the equipment used.

Norma iso 17020 2004 requires inspection bodies to manage inspection equipment

properly, ensuring it is calibrated, maintained, and suitable for the intended purpose.

Regular calibration against national or international standards helps prevent

measurement errors and maintains the integrity of inspection outcomes.
