Registration
Connecticut follows the requirements of NIST Handbook 44, along with applicable state laws and regulations.
Commercial weighing and measuring devices used in Connecticut must be registered annually with the Connecticut DCP.
Commercial scales must have a valid NTEP Certificate of Conformance and meet applicable requirements of NIST Handbook 44.
Calibration
A Connecticut-registered weighing and measuring device repairer is required to install and calibrate the scale before it is used commercially.
The repairer must notify the Connecticut DCP in writing within 48 hours after installing, repairing or adjusting the scale and certify that the device conforms to applicable state requirements.
The scale is then subject to inspection by the Connecticut DCP Weights and Measures Program to verify accuracy and compliance.
Maintenance
Have the scale regularly serviced and calibrated to maintain accuracy.
Commercial scales are subject to inspection by the Connecticut DCP Weights and Measures Program.
Scales that fail inspection may be removed from service until corrected and may be subject to enforcement action.
