We know that a formal laboratory work needs to be prepared, so what should we prepare? Let's take a look!
Personnel are the primary factor in the technical requirements of the laboratory, and the laboratory manager should ensure the capabilities of all personnel who operate the equipment, perform testing and/or calibration, evaluate results, sign test reports and calibration certificates. It is necessary to confirm and authorize the training and assessment of various types of personnel, qualifications or qualifications. It is necessary to stipulate the scope of duties of all types of personnel, hold certificates and supervise the calibration activities.
2. Facilities and environmental conditions
The laboratory's facilities and environmental conditions have a significant impact on the accuracy and effectiveness of the calibration results. Therefore, the laboratory's facilities and environmental conditions should be effectively controlled. The laboratory should ensure that its environmental conditions do not invalidate the results. Or adversely affect the required measurement quality. It is monitored and maintained by a professional person to ensure the quality of the calibration results.
3. Calibration method and its confirmation
The laboratory should use appropriate calibration methods according to its own work ability, and complete the relevant calibration procedures, verification procedures or work instructions to ensure the consistency of the calibration technology. Complete selection, formulation, confirmation of deviation from calibration methods, assessment of measurement uncertainty, and data control. Regardless of the form of documentation, the basis for the same calibration activity should be consistent. The laboratory should give priority to the use of national standards, industry standards, departmental standards, and relevant work instructions, standards, operating manuals, technical specifications and reference materials should be valid.
4. Equipment and facilities
Equipment is a must-have resource for calibration/testing. The laboratory should be equipped with all equipment capable of performing calibration work and data processing, and to achieve the required accuracy of these equipment and supporting facilities, while meeting the requirements of the corresponding calibration specifications. The equipment shall be subjected to standard traceability, periodic calibration, verification or verification as required, and a calibration and calibration plan shall be prepared in accordance with the requirements of the calibration cycle.
5, measurement traceability
All equipment used for inspection/calibration that has a significant impact on the accuracy or effectiveness of the inspection, calibration, and sampling results, including auxiliary measurement equipment (eg, equipment used to measure environmental conditions), should be calibrated prior to commissioning. The laboratory shall establish a planning and calibration procedure for equipment calibration and perform the traceability procedure of the measurement standard. The highest standard of the system or department shall be sent to the first-level metrology institution or traced to the highest national measurement standard.
6. Disposal of the piece
The piece should be properly disposed of in order to prevent the performance and calibration results of the piece being damaged due to improper handling. The piece should be uniquely identified. The design and use of the marking system should ensure that items are not confused in kind or in the records and other documents involved.
These are some basic preparations. Of course, there are still a lot of preparations that have not been written. I hope these can help you.
