The National Accreditation Board, NAB, is the Irish organisation for the accreditation of laboratories and certification bodies. The NAB is the sole national body responsible for accreditation in accordance with relevant International Organisation for Standardisation, ISO, standards, the EN 45000 series of European standards and the applicable national and international regulations.
Laboratory accreditation granted by the NAB is commonly referred to as "ILAB" accreditation. The ILAB scheme is voluntary and it is open to any laboratory that performs objective testing or calibration to apply for accreditation under this scheme. Quality of work and objectivity are the major elements considered when establishing the suitability of a laboratory for accreditation. The NAB has to date accredited one laboratory with a scope of accreditation for the calibration of flow meter devices over a specific range of flow.
