About Accreditation

The Irish National Accreditation Board (INAB) is the national body with responsibility for the accreditation of laboratories, certification bodies and inspection bodies.  It provides accreditation in accordance with the relevant International Organisation for Standardisation ISO 17000 series of standards and guides.

It is the statutory body responsible for Good Laboratory Practice (GLP).

INAB was established in 1985 and is a Committee of the Health and Safety Authority under the Industrial Development (Dissolution of Forfas) Act 2014.

In January 2010, the European Commission was notified by the Department of Business, Enterprise, and Innovation (now the DBEI) that INAB is the sole accreditation body for Ireland in line with regulation EC/765/2008. 

INAB has identified and analysed its relationship with related bodies within Government for its ranges of activities and within its present structure and concludes that no potential conflict of interest exists.

INAB’s Functions Include: 

  • Accreditation of Testing and Calibration Laboratories ISO 17025, ISO 15189
  • Accreditation of Certification Bodies IS0 17021-1, IS0 17024, ISO 17065
  • Accreditation of Inspection Bodies ISO 17020
  • Accreditation of Reference Material Producers ISO 17034
  • Accreditation of EMAS Verifiers under the Eco-Management and Audit Scheme (EMAS) – Council Regulation (EC) 1221/2009
  • National Compliance Monitoring Authority for Good Laboratory Practice SI 18 of 2020 EC Directive 2004/9/EC 
  • Accreditation for the purposes of notification to European Product Directives.

Benefits of Accreditation

The accreditation process determines, in the public interest, the technical competence and integrity of organisations offering testing, proficiency testing provision, examination, validation and verification, inspection, calibration and certification (often known collectively as evaluation services or conformity assessment services).

INAB accreditation ensures that certificates and test results are acceptable worldwide. Accreditation eliminates the need for multiple assessments when goods cross borders, giving Irish industry the best competitive advantage possible in what is an ever-expanding and aggressive marketplace.

Accreditation, which operates across all market sectors, provides an impartial assessment against internationally recognised standards. It offers key benefits as outlined below:


Accreditation is the preferred mechanism for ensuring public confidence in the reliability of activities that impact on health, welfare, security and the environment. Accreditation is used, therefore, to identify bodies competent for the implementation of government policies and regulations.


Accreditation gives consumers confidence through ensuring consistently high standards in the quality and safety of products or services purchased.


Accreditation is an essential tool for decision making and risk management.  Organisations can save time and money by selecting an accredited (and therefore competent) supplier.

Accreditation can provide a competitive advantage and facilitates access to export markets within Europe and beyond – with the aim of “tested or certified once, accepted everywhere”.

Accurate measurements and tests carried out in compliance with best practices limit product failure, control manufacturing costs and foster innovation.

Accredited Organisations

Accreditation is chosen by an organisation because of the competitive advantages it affords, through access to a given market via independent assessment and demonstration of compliance with international requirements.

Accreditation is objective proof that organisations have the competence to comply with best practice.  It is the internationally recognised system that is used to develop and sustain high standards of performance.  It is often a prerequisite for eligibility to tender for international projects.
