ANSI/NCSL Z540 Certification Definition

ANSI/NCSL Z540 may refer to either ANSI/NCSL Z540.1 or ANSI/NCSL Z540.3, both of which are standards facilitated by the American National Standards Institute (ANSI) and the National Conference of Standards Laboratories (NCSL). ANSI/NCSL Z540.1 has been replaced by two separate standards-ISO/IEC 17025 and ANSI/NCSL Z540.3.

ANSI/NCSL Z540.1 was intended for calibration laboratories. ANSI/NCSL Z540.3 gives requirements for the calibration of an organization's equipment when used in the manufacturing, modification or testing of products.

Compliance to these standards can be verified by third party certifying bodies. The evaluation may be completed in addition to an ISO/IEC 17025 audit. For an organization to maintain certification, they will be subjected to annual or regularly scheduled audits where the organization's compliance with the standard is evaluated by the certifying body.
