All changes to the record should have the signature or initials of the person who made the change to clarify their responsibility. Therefore, when making measurements and using measurement results, the measurement uncertainty must be considered. Authenticity is the original record that faithfully reflects the actual situation of local verification and calibration at that time, reflects the data and phenomena in the verification and calibration process, and uses measuring instruments, equipment, and environmental conditions.
In the case that the national measurement standard cannot be traced to the source, the laboratory should provide satisfactory evidence of relevant results, such as participating in an appropriate inter-laboratory comparison or proficiency test. Truthfulness, completeness, accuracy and reliability are the most basic requirements for original records. The format of the qualified verification and calibration certificate shall be standardized,China belt tensioner bearing kit and the content shall be complete, clear, accurate and objective, and shall contain all the information of verification and calibration results.
The maintenance of instruments and standard measurement instruments should be carried out regularly, and maintenance work such as dust removal and rust prevention should be carried out on the instruments and standard measurement instruments in accordance with the maintenance procedures in the program documents. 2 Ensuring the quality of verification and calibration original records and certificates Metrology is a scientific and rigorous work.
Integrity is to make a standardized and complete original record form. From the verification and calibration original records to the issuance of certificates, every link must not be sloppy. To maintain authenticity requires our metrology staff to take a scientific work attitude, take every verification, calibration process and every measurement data seriously, and never allow sloppy and falsification. Verification and calibration certificates are ‘products’ produced by metrology staff and are a concentrated expression of the quality of metrology work.
