Model Approval Certificate is valid for one year.  After the validity period, manufacturers or suppliers may need to renew the certification.

Model Approval Certification is typically associated with the specific model or design of a measuring instrument. In case if manufacturer introduces a new model he has to apply for a separate certificate.

If a measuring instrument fails to meet the required standards during the certification process, the manufacturer may need to make necessary changes to his product then he has to reapply for certification.

After obtaining Model Approval Certification, manufacturers or suppliers may be subject to post-certification obligations, such as periodic audits, inspections, or verification of the certified models. Compliance with ongoing regulatory requirements and maintaining the accuracy of the measuring instruments are crucial.
