(a) Metrology Services and Laboratory Traceability. The department's metrology laboratory shall maintain NIST recognition and certification of international metrological traceability to the International System of Units (SI), as necessary to provide a service to calibrate standards needing the same international metrological traceability.

(b) The department adopts by reference NIST Handbook 143-State Weights and Measures Laboratories Program Handbook.
