A certificate of authentication Where the implementation of verification procedures based on measurement, verification of the conclusion of the "qualified" issued by the verification certificate. Each type of measuring instruments should be certified in accordance with the requirements of its metrological verification procedures. Certificate name for the "certificate of verification". Its cover includes: certificate number, page number and total number of pages; issued by the certificate of the unit name; commissioned by the party or the applicant's unit name; the name of the measuring instruments being tested, model specifications, manufacturer, factory number; test conclusions (should be filled in "qualified" or in the "qualified") "before the title of the accuracy level); verification, verification, the competent person with an ink pen signature; date of verification: X years X months X; valid until: X years X months X days. Certificate of verification should include the following: page number and total number of pages; the original record number of the test; the test based on the name and number of the measurement and verification procedures; the test of the measuring instruments and equipment used in the measurement of the name, model, number, test or calibration certificate number (validity), technical characteristics (such as the accuracy level, the uncertainty of the value or the maximum permissible error); verification of the Location (such as the laboratory or the commissioning party site); the environmental conditions of the test (such as temperature, humidity); the test procedures specified in the test items (such as appearance inspection, various measurement characteristics, display value error, etc.) of the conclusions and data. If the calibration process of the object to be adjusted or repaired, it should be noted that after the repair, and as far as possible to give the results before and after the repair of the calibration. Should also include other content required by the verification procedures. Test certificate content to express the end, there should be a final sign.
When the conclusion of the test is "unqualified", the certificate issued by the name of the "test results notice". The conclusion of the "unqualified" or "see the test results", only give the date of the test, do not give the validity of the test results should be pointed out in the unqualified items. Other requirements and "certificate of verification" the same.
(B) calibration certificate
Where based on national calibration specifications, or non-compulsory calibration of measuring instruments based on the relevant part of the measurement and verification procedures, or based on other confirmed calibration method of calibration, the name of the certificate issued by the "Certificate of Calibration" (or "calibration report"). Calibration report").
Calibration certificate should generally contain the following information: certificate number, the original record number, page number and total number of pages, the name and address of the unit issuing the certificate, the name and address of the commissioning party; calibrated measuring instruments or measuring instruments, the name of the specifications of the model, the manufacturer, the factory number; calibration, verification, approval of the personnel with an ink pen signature (approver's position can be printed); the date of acceptance of the item being calibrated: The location of calibration (e.g., the laboratory or the commissioning party's site); the environmental conditions during calibration (e.g., temperature value, humidity value); the result data of the calibration items (e.g., display value error, correction value or other parameters) and their measurement uncertainty according to the calibration method document. If the object to be calibrated during the calibration process is adjusted or repaired, it should be noted that after the adjustment, and as far as possible to give the calibration results before and after the adjustment. Regarding the calibration interval, if it is the traceability calibration of measuring standard instruments, the calibration interval should be given in accordance with the provisions of the measurement calibration specification. -Generally, calibration intervals are not recommended on the calibration certificate. When requested by the customer, calibration intervals may be given on the calibration certificate. The content of the calibration certificate to express the end, there should be a final sign.
(C) test report
(1) measuring instruments for new products or imports of measuring instruments type evaluation test should be based on JJF1015-2002 "measuring instruments type evaluation and type approval of the General Specification" Appendix C requirements, issued "measuring instruments type evaluation report ". Type evaluation report includes: report number, measuring instruments or new products imported measuring instruments name, model specifications, the number of prototypes and each prototype number, apply for type evaluation of the unit's name and address, the date of receipt of the prototype, the test date and the date of issuance of the report, the application and commissioning (application number, contact information, commissioned by the unit of information, etc.), to undertake type evaluation of the unit of information, type evaluation Based on the technical documents, type evaluation of the test site and its environmental conditions, the use of measuring instruments and other measuring equipment information, measurement data and conclusions of each test item, the overall conclusion of the type evaluation, the signature of the inspector, reviewer, approver.
(2) the net content of quantitatively packaged goods inspection, according to JJF1070-2005 "net content of quantitatively packaged goods measurement and inspection rules," "Appendix J: Net Content of Quantitatively Packaged Goods Inspection Report Format," issued by " Net content of quantitatively packaged goods inspection report". Inspection report, including the report number, commodity name, model specifications, the name of the unit inspected, the name of the production unit, test category, inspection unit seal, inspection unit statement, inspection unit's contact information, complaint phone number, sampling, test conditions, test basis, test results, the overall conclusions, the report describes the main inspector, reviewers, approvers of the signatures of the staff, position, date.
