The accreditation of inspection bodies is a cornerstone for ensuring reliability, independence and technical competence in conformity assessment activities. In Portugal, the ISO/IEC 17020 standard establishes the requirements that any organisation wishing to provide inspection services in a credible and internationally recognised manner must meet.
In this article, we explore the fundamentals of the standard, the types of inspection bodies, the accreditation process in Portugal coordinated by IPAC (Portuguese Institute for Accreditation), and the main applications in environmental and industrial contexts.
Types of Inspection Bodies (A, B, C)
The ISO/IEC 17020 standard establishes three distinct categories of inspection bodies, each with different implications regarding impartiality and independence:
Type A — Independent Bodies
A Type A body operates in complete independence from any interested party. It has no links with manufacturers, suppliers, owners or users of the products or services it inspects. This type is the most demanding in terms of demonstrating impartiality, but it also offers the highest degree of credibility to clients. It is particularly suitable for environmental inspections, regulatory compliance audits and critical safety assessments.
Type B — Internal Bodies
A Type B body is organised within a larger entity (for example, a quality department within a manufacturing company). Although it has a functionally separate and defined structure, it remains within the same organisation. It presents greater challenges in demonstrating impartiality, but can be viable in contexts where inspection serves internal processes or controlled supply chain operations.
Type C — Bodies with Limited Links
A Type C body may have limited links with interested parties, provided these do not compromise impartiality. For example, a consultant who works with companies in a specific sector, but maintains robust procedures for managing conflicts of interest. It requires clear and rigorous documentation of how impartiality is safeguarded.
Each type requires different levels of documentation, functional separation and demonstrations of independence during the accreditation evaluation.
Technical and Management Requirements
To obtain and maintain accreditation under ISO/IEC 17020, an inspection body must establish robust systems in several critical areas:
Qualified and Competent Personnel
Inspectors must possess relevant academic and professional qualifications, specific training in inspection procedures, and demonstrated technical competence through testing or evaluation. The standard requires maintenance of updated competence records and continuing training programmes.
Documented Procedures
All inspection procedures, from planning to final reporting, must be documented and accessible. This includes inspection criteria, sampling protocols (where applicable), evaluation methodologies and reporting quality standards.
Calibrated and Traceable Equipment
Any measuring instrument used must be calibrated with metrological traceability assured. Records of calibration, preventive maintenance and functional checks must be maintained systematically.
Complaint Management and Corrective Actions
A robust system for receiving, investigating and resolving complaints is fundamental. This demonstrates accountability and commitment to continuous improvement in service quality.
The Accreditation Process in Portugal (IPAC)
The accreditation of inspection bodies in Portugal is coordinated by IPAC (Instituto Português de Acreditação), in line with national and European regulatory frameworks.
Process Phases:
-
Application and Prerequisites
The interested body submits a formal application to IPAC, demonstrating that it has already implemented the ISO/IEC 17020 requirements. It must be legally established and have documented experience in inspection activities. -
Documentation Submission
The body provides quality manuals, technical procedures, personnel curricula vitae, equipment records and evidence of competence. The documentation is reviewed for conformity with the standard. -
On-Site Evaluation
Technical evaluators from IPAC visit the premises, interview personnel, inspect equipment and observe inspection activities. This is a detailed process that may last several days, depending on complexity and scope. -
Accreditation Decision
Following evaluation, IPAC issues a decision: full accreditation, conditional accreditation (with minor non-conformities to be corrected), or rejection. Bodies with conditional accreditation have a period (typically 90 days) to comply. -
Surveillance and Re-Accreditation
Accreditation is valid for 3 years, with annual surveillance audits. Re-accreditation requires a complete evaluation similar to the initial process.
Timelines vary according to the type of inspection and complexity, but typically take between 6 to 12 months from application to final decision.
Sectors of Application in Portugal
ISO/IEC 17020 applies to a wide spectrum of activities in Portugal:
- Environmental Inspection: Assessment of environmental compliance, energy audits, waste and water inspections
- Food Safety: Inspection of food processing facilities, hygiene audits
- Construction and Structures: Inspection of buildings, structures, foundations and safety systems
- Industrial Safety: Assessment of machinery, pressure equipment, fire protection systems
- Transport: Periodic vehicle inspections and homologations
Organisations operating in these areas and seeking to differentiate themselves through service quality and reliability greatly benefit from ISO/IEC 17020 accreditation.
Conclusion
Accrediting an inspection body under ISO/IEC 17020 is not merely a mark of regulatory compliance — it is a tangible demonstration of competence, impartiality and excellence. For clients, it assures that inspections were conducted by qualified professionals with robust quality systems. For the organisation, it opens doors to new markets, increases credibility with stakeholders and positions the company as a leader in reliability.
