ANAB is committed to superior accreditation services, including those for proficiency test providers following ISO/IEC 17043 and/or domestic standards such as TNI Standard EL-V3-2008, TNI Standard V1M2-2009, and the relevant elements of ISO/IEC 17025. (Click for information about TNI PT provider accreditation)

The program provides users of proficiency testing programs increased confidence that the programs being relied on are being operated competently in accordance with the specified technical and management system requirements. ANAB accreditation processes allow you the opportunity to assure your customers of your compliance with international standards and international recognition of good practices. Our policy is to accredit proficiency test providers only to tests that have been approved and published on the proficiency test provider scope of accreditation.

Accreditation may entail any of a lengthy list of materials used for critical and measurable properties in testing and calibration. Much of the value for proficiency test provider accreditation, however, relates to international confidence in the proficiency testing schemes themselves. This leads to international trade assurances and assurances that international guidelines are followed in the production, labeling, and assignment of property values to materials, including stability and homogeneity determinations that are then factored in the proficiency testing results reported.

As with our other programs, accreditation involves assurance of technical competence and good quality management practices, but also adds verification of the proficiency test management of the provider. Our management and technical staff assure high-quality service, integrity, independence, impartiality, confidentiality, highly-trained experts and assessors, statistical expertise, and unmatched customer service.

ANAB maintains impartiality as required in Section 4.3 of ISO/IEC 17011 (see also Responsibilities and Obligations of the Customer, Appendix A of the ANAB application for Proficiency Test Provider accreditation). ANAB management, staff, assessors, and experts are free from any commercial, financial, and other pressures that could influence the results of the accreditation process for all ANAB conformity assessment programs, including the requirements of the TNI programs. Agreements and statements (e.g., confidentiality agreements) exist for ANAB management, staff members, assessors, experts, and Accreditation Council members.
