Verification of measuring instruments

Verification is a procedure performed by a competent verification laboratory or notified body to assess conformance of a measuring instrument to relevant requirements and to put a verification mark if requirements are met.

The purpose of verification is to protect interests of citizens and state from possible harm caused by incorrect measurements. Verification of measuring instruments is an obligation regulated by legal acts of Estonia and European Union.
