ANSI/NCSL Z540.1-1994 (R2002)

Withdrawn as an active standard (July 2007) and superseded by ANS/ISO/IEC 17025:2005 for part 1 and ANSI/NCSL Z540.3-2006 for part 2.

This standard provides a mechanism for promoting confidence in calibration laboratories and measuring and test equipment when it can be shown that they are operated in compliance with its requirements. The intent of this Standard is that laboratories meeting its requirements comply, for calibration activities, with the relevant requirements of the ANSI/ASQC Q90 series of standards, including those of the model described in ANSI/ASQC Q92 when they are acting as suppliers producing calibration results. This Standard includes the requirements relevant to calibration laboratories of ISO/IEC Guide 25 (1990) and requirements relevant to the quality assurance of measuring and test equipment derived from MI-STD 45662A.
