ANAB National Environmental Field Activities Program (NEFAP) Accreditation

The purpose of the National Environmental Field Activities Program (NEFAP) is to establish and implement an accreditation program for field sampling and measurement organizations (FSMOs).

The TNI Standard for FSMOs is modeled after ISO/IEC 17025:2005, General Requirements for the Competence of Testing and Calibration Laboratories. TNI Standard Volume 1 is the FSMO Competency Standard, which is the same international standard for fixed laboratories. TNI Standard Volume II is the FSMO Accreditation Body (AB) Requirements to Accredit FSMOs. The AB Standard is based on ISO/IEC 17011:2004, Conformity Assessment - General Requirements for Accreditation Bodies Accrediting Conformity Assessment Bodies.

The TNI standard is intended as an application of ISO/IEC 17025:2005(E). The ISO/IEC clauses are provided in italics with the additional TNI clauses in normal font. Users of this standard should make the following substitutions and recognize that the context may require minor variations to these terms:

Laboratories or Laboratory Field Sampling and Measurement Organizations (FSMOs)

Test and/or calibration Environmental Sampling and Field Measurement

Tests and/or calibrations Environmental Sampling and Field Measurement Activities

Unless the contrary is clearly indicated, all references to singular nouns include the plural noun, and all references to plural nouns include the singular. Some clauses in this Standard contain notes. The notes are used to explain a particular requirement or to provide clarifying examples. The notes do not supersede or modify requirements of the Standard and do not convey any additional requirements.

The specific criteria for field sampling and measurement activities are contained in The NELAC Institute Field Sampling and Measurement Organization (TNI FSMO) Volume 1, adopted May 1, 2007.
