Trade:
Scales used for legally regulated goods (e.g. food, medicines).
Medicine:
Scales used for weighing patients in medical facilities.
Other applications:
In some specific fields, scales with a defined accuracy and verification certificate may also be required.
Certification issued by a metrological authority confirms that the device meets the accuracy requirements set by regulations.
⚖️ When must a retail scale be verified (legalized)?
A new scale must be verified before it is used for trade purposes.
Certification (verification) must be repeated every 2 years (for devices certified after April 26, 2019) or every 3 years (for those verified before that date).

The national authority responsible for verifying measuring instruments.
