NIST Handbook 150-2, 2019 edition, presents the technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Calibration Laboratories Program. The 2019 edition of NIST Handbook 150-2 supersedes and replaces the 2016 version of NIST Handbook 150-2. The 2019 edition has been updated to reflect the requirements of ISO/IEC 17025:2017 and has added new normative annexes covering specific technical areas. These annexes set out technical requirements not covered in NIST Handbook 150 that are applicable to a laboratory recognized as competent to carry out calibrations in the specific technical areas covered. The annexes form a normative part of this handbook, meaning they contain provisions that laboratories must meet in order to conform to the requirements for accreditation. Calibration laboratories use NIST Handbook 150-2 in developing the management and technical systems that govern their operations. Laboratory customers, regulatory authorities, and accreditation bodies may also use it as a basis upon which to judge the competence of laboratories.
