Registration
Arizona follows the requirements of NIST Handbook 44, along with applicable state laws and regulations.
Arizona requires commercial weighing and measuring devices to be licensed by the Arizona WMSD.
Commercial scales must have a valid NTEP Certificate of Conformance and meet applicable requirements of NIST Handbook 44.
Calibration
A Registered Service Representative (RSR) working for a licensed Registered Service Agency (RSA) is required to install and calibrate the scale before it is used commercially.
The RSR may place the scale into service and must complete the required Placed in Service Report (PISR).
The scale is then subject to inspection by the Arizona WMSD.
Maintenance
Have the scale regularly serviced and calibrated to maintain accuracy.
Commercial scales are subject to inspection by the Arizona WMSD to verify accuracy and compliance.
Scales that fail inspection may be removed from service until corrected and may be subject to enforcement action.
