MANAGEMENT AND OPERATING (M&O) CONTRACTOR STANDARDS AND
CALIBRATION PROGRAMS TO REFERENCE ISO/IEC 17025:2017
In 2017, the International Organization for Standardization (ISO) revised ISO/IEC 17025: General
Requirements for the Competence of Testing and Calibration Laboratories. Accrediting bodies
provided a short grace period for calibration and testing labs to implement the new standards, but
now all accredited testing and calibration laboratories are accredited to ISO 17025:2017.
Chapter 13.2 of the Development and Production (D&P) Manual references an older version of
ISO/IEC 17025; however, because the 2017 version “cancels and replaces” prior editions, and
external calibration providers are accredited to the 2017 version, the Primary Standards Laboratory
(PSL) will conduct all future technical surveys against ISO/IEC 17025:2017 in addition to the
requirements in NNSA Policy (NAP) 401.1A, Weapon Quality Policy; the D&P Manual; and the PSL
memorandum.
All M&O Contractors, Contractor Standards Labs, and Metrology Organizations will be evaluated to
ISO/IEC 17025:2017 until the D&P Manual, Chapter 13.2, is replaced by new Defense Program
Business System (DPBPS) requirements.
