ISO/IEC 17020 Standard
General Requirements for the Operation of Various Types of Bodies Performing Inspection
The ISO/IEC 17020 standard is the leading international benchmark that specifies the requirements for the competence of inspection bodies, as well as the impartiality and consistency of their inspection activities. It aims to build trust in organizations that examine products, processes, services, and installations to determine their conformity with specific standards or regulations.
1. Overview of the Standard
Developed jointly by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), ISO/IEC 17020 does not just focus on technical competence. It establishes a rigorous framework to guarantee integrity, impartiality, and independence. The standard classifies inspection bodies into three distinct types based on their degree of independence:
Type A (Third Party): Fully independent inspection bodies that are separate from all involved parties.
Type B (First/Second Party): In-house inspection bodies that form an identifiable part of an organization and provide services only to their parent company.
Type C (First/Second/Third Party): Inspection bodies that form an identifiable part of an organization but may also provide inspection services to external clients.
2. Target Sectors Served by the Standard
Due to its high flexibility, ISO/IEC 17020 is universally applicable across a broad spectrum of industrial and service sectors, including:
Engineering and Construction: Inspection of buildings, bridges, structural steelwork, cranes, and heavy lifting equipment.
Oil, Gas, and Energy: Examination of pipelines, storage tanks, pressure vessels, and power generation plants.
Automotive and Transportation: Periodic roadworthiness testing of vehicles, and safety inspections for railways and aviation.
Environmental and Public Health: Inspection of waste management systems, air quality monitoring, and water systems.
Agriculture and Food Safety: Inspection of agricultural shipments, slaughterhouses, and catering facilities to ensure food safety compliance.
Customs and International Trade: Pre-shipment inspections (PSI) of goods to verify compliance with national or international import standards.
