Accreditation standards are developed by Expert Committees using a consensus process that includes the elements of openness, balance, due process, and consensus as established by Circular A-119 published by the US Office of Management and Budget.
On August 24, 2009, the National Environmental Laboratory Accreditation Program (NELAP) Board adopted the following TNI standards for use in the state recognized laboratory accreditation programs. By separate vote, the NELAP Board established July 1, 2011, as the official implementation date. The July 1, 2011, implementation date allows state accreditation bodies sufficient time to change state regulations to reflect the new standards, as well as allowing laboratories time to come into compliance with the new standards. Prior to implementing the new standards, the NELAP Board will be working with other TNI committees to ensure that all policies, checklists and SOPs needed for implementation of the new standards are in place for the state accreditation bodies.
The accreditation standards below are freely available for download. However, it is important to note that some modules contain language from ISO/IEC 17025 and 17011. Because of copyright restrictions, the publicly available TNI documents do not contain the ISO/IEC copyright protected language, but do reference applicable ISO clauses. In these situations, it is useful to read the TNI Standard along with the ISOI/IEC standard. Wherever an ISO clause is referenced (in italics), the language from that clause is applicable. Any additional TNI language then follows, in plain text, as a NOTE or as an additional numbered standard item. TNI has produced a version of these standards where the ISO/IEC language is combined with the TNI language. These combined documents are available for prices that essentially recover the cost of the license agreements for use of the ISO/IEC language.
