Measurement value traceability management system

Management System of Measurement Value Traceability

I. Measurement Value Traceability

1. Measurement value should be able to trace back to the international or national benchmarks according to the table of national verification system.

2, the verification of measuring equipment through the quantitative value transfer to realize.

1) the enterprise's highest measurement standard to the upper level of legal metrological certification bodies traceability;

2) the enterprise has established a measurement standard with the work of measuring equipment to the standard traceability;

3) the enterprise has not yet established a measurement standard with the work of measuring equipment directly to the legal metrological certification bodies traceability.

Two, confirmed

1, mandatory verification

1) for trade settlement, safety and security, health care, environmental monitoring of measuring equipment and the highest measurement standard included in the mandatory verification;

2) mandatory verification of measuring equipment separate accounts, and the implementation of fixed-point regular verification;

3) authorized self-test of mandatory verification of measuring equipment, the verification is strictly in accordance with the verification regulations. Inspection is carried out in strict accordance with the inspection procedures.

2, periodic inspection

1) for process, quality inspection, business management, energy measurement and internal material measurement equipment included in the cycle of inspection;

2) included in the cycle of inspection of measuring equipment monthly preparation of weekly inspection plan, approved by the measurement room to implement;

3) Inspection of measuring equipment in accordance with the inspection procedures.

3, a one-time test

1) Where the measurement equipment for non-important testing points and low-value consumable included in a one-time test;

2) included in a one-time test of measuring equipment only in the warehouse or issued a one-time confirmation of compliance is no longer confirmed;

3) Where the inclusion of a one-time test of the measurement equipment is only for the principle of the provisions of the account will not be built.

4, calibration

1) the country does not have a test protocol or although there is a test protocol, but the proximity of nowhere to send the measurement equipment included in the self-calibration;

2) calibrated according to their own self-calibration protocols.

5. Not Required to Confirm

1) Measurement equipment that has no measurement value requirement and is only used as an indication for reference purposes, as well as measurement equipment that is difficult to dismantle and is not important on imported equipment or integrated assembly equipment, are included in the list of not required to confirm;

2) Measurement equipment that does not need to be confirmed can be adjusted at any time in accordance with the actual situation.

Three, inspection records

1, where the key positions on the important measurement equipment after passing the inspection must have inspection records.

2, other positions in the measurement equipment may not make inspection records, but there must be a certificate of inspection.

3, the same model, the same specifications, the same accuracy of the measuring equipment can be combined with a certificate of verification.

Four, measurement standards

1, measurement standards to carry out verification of the project's requirements for the configuration, through the government measurement of the administrative departments of the assessment of qualified to carry out the work.

2, measurement standards are stored in the measurement standard room, by the person responsible for custody.

3, the measurement of standards included in the mandatory calibration, regularly sent to the higher measurement of the Department of calibration, calibration of qualified put into use, the test failed for downgrading or scrapping. Strictly prohibit the use of unqualified or more than the validity of the verification of measuring standards.

V. Metrological calibration room

1, metrological calibration room is the storage of measuring standards and carry out metrological calibration of the premises.

2, measurement and calibration room should be put shock, moisture, dust, no corrosion, temperature, humidity and other environmental conditions should be in line with the requirements of the regulations.

3, measurement and calibration room should be kept quiet, clean, no noise, shall not do nothing to do with the work of calibration, shall not be stored and calibration of sundries, no one into.

4, metrological calibration room at least twice a week to clean to ensure that the entire calibration room floor windows and doors clean and clean measurement standards.

5, measurement of the calibration room by a person responsible for the management, in the calibration work is responsible for recording the temperature and humidity of the calibration room.
