The requirements concerning the design and manufacture of measuring instruments consist of the item-specific requirements appearing in legislation and standards or recommended standards. Under the statutes, measuring instruments shall be subject to type approval and verification. The requirements concerning the structure and markings of measuring instruments shall be taken into consideration already at the design stage. Cooperation with Tukes and notified bodies is the best way to avoid in advance any erroneous decisions. Tukes also supervises manufacturers and provides information about requirements.
Manufacturers and subcontractors execute designs. Manufacturers are ultimately responsible for the conformity of their products.
Notified bodies may act as voluntary verifier of the conformity of measuring instruments.
