Inspection Body Accreditation Program

All organizations seeking accreditation as an Inspection Body must meet the general requirements of ISO/IEC 17020:1998 as outlined in A2LA document R301 - General Requirements - Accreditation of ISO/IEC 17020 Inspection Bodies. A2LA's official application of the standard is consistent with the current version of IAF/ILAC-A4 Guidance on the Application of ISO/IEC 17020. (IAF/ILAC-A4 Guidance on the Application of ISO/IEC 17020 may be obtained free of charge in the documents section of the ILAC web site WWW.ILAC.ORG or by contacting A2LA headquarters).

In effect, A2LA accreditation attests that an inspection body has demonstrated that:

  1. it is competent to perform specific inspections or specific types of inspections; and
  2. its quality system is documented, fully operational and addresses and conforms to all elements of ISO/IEC 17020-1998, IAF/ILAC A4:2004 and A2LA official applications of these standards;
  3. it is operating in accordance its quality system; and
  4. it conforms to any additional requirements of A2LA or specific fields or programs necessary to meet particular user needs.

A2LA recognizes the very close relationship between inspection, sampling, testing and measurement yet understands that inspection includes a variety of activities not covered in testing laboratory accreditation. Inspection includes the examination of materials, products, components, assemblies, cargoes and consignments, usually for compliance with specified criteria. It includes visual examination and associated work, and may be more directly focused on products. A2LA staff can advise potential applicants of the appropriate field of inspection for the accreditation of their inspection activities. An inspection body which is engaged in testing, measurement or sampling work may apply for accreditation for this work concurrently with its application for accreditation for inspection.
