    In accordance with these Guidelines, guidelines for MC calibration for specific types of IMS should be developed.

    With the release of these Guidelines, the "Methodology. Measuring channels of information-measuring systems. Organization and procedure for verification: RD 34.11.205-88" (M.: SPO Soyuztekhenergo, 1988) becomes invalid.

    1.1. The purpose of calibration is to determine and confirm the actual values ​​of MX and (or) suitability for the use of IC, which are not subject to state metrological control and supervision.

    1.2. IR calibration must be carried out as a set (complete method).

    If the calibration cannot be carried out by the complete method, then it is carried out element by element (element by element method).

    The elements of IC IIS are understood as separate measuring instruments (SI) or sets of SI and other technical means, including communication lines used in IC IIS.

    When performing element-by-element calibration, the primary measuring transducer (PMT) (or PMT and MT) and the electrical path of the IC (ET IC) are calibrated separately. Calibration of the ET IC is carried out in accordance with the methodology described in these Guidelines.

    1.3. All MCs are calibrated at the intervals specified in the certificate of metrological attestation (MA).

    1.4. The list of MCs to be calibrated is compiled by the metrological service of the power enterprise and approved by the chief engineer.

    1.5. IMS measuring channels subject to state metrological control and supervision, in accordance with Art. 13 of the Law of the Russian Federation "On ensuring the uniformity of measurements" must be subjected to periodic verification.

    The list of MCs to be verified is compiled by the metrological service of the power enterprise and sent to the territorial body of the State Standard of Russia.

    Verification of IC is carried out according to the methodology approved by the State Metrological Service, or according to the methodology set out in these Guidelines and agreed with the territorial body of the State Standard of Russia.

    Verification intervals are established by the territorial body of the State Metrological Service. Adjustment of calibration intervals is carried out by the body of the State Metrological Service in agreement with the metrological service of the power enterprise.

    6.4. Primary calibration can be performed by the metrological services of manufacturers.

    6.5. Measuring instruments that are in operation or stored at certain intervals between calibrations (MCIs) are subject to periodic calibration.

    6.6. Each copy of measuring instruments must undergo periodic calibration. Periodic calibration may not be subject to measuring instruments that are in long-term storage and conservation.

    6.7. The results of periodic calibration are valid during the calibration interval.

    6.8. The first calibration interval is set at type approval.

    6.9. The calibration intervals are corrected by the metrological service, which calibrates based on the results of previous calibrations. The adjustment must be agreed with the HOMS of the industry.

    6.10. Extraordinary calibration is carried out during operation (storage) of measuring instruments at:

    Loss of the calibration certificate;

    Commissioning of measuring instruments after a long (more than one calibration interval) storage;

    Re-adjustment or adjustment, known or suspected impact on the measuring instrument, or unsatisfactory performance of the instrument.

    6.11. Inspection calibration is carried out to determine the suitability for the use of measuring instruments in the implementation of metrological or state geodetic supervision.

    6.12. Inspection calibration is reflected in the calibration certificate.

    6.13. Inspection calibration is carried out by employees of the BOMS or GOMS with the participation of representatives of the State Geosurveillance in the presence of a representative of the metrological service being checked.

    Specialized documents of the type "Methods and means of calibration", approved in the prescribed manner;

    Sections of operational documentation containing methods and means of calibration that have passed examinations in the process of acceptance (testing) of measuring instruments.

    6.15. Calibration charts.

    6.15.1 Metrological services calibrate measuring instruments on the basis of calibration schedules compiled by metrological services that have the right to calibrate SI, or by metrological services of enterprises, organizations that do not calibrate themselves.

    6.15.2. Calibration schedules are compiled according to the types of measurements in form 5 (Appendix B).

    6.15.3 Calibration schedules are drawn up for a period set by the owners of measuring instruments, usually for one year. Calibration schedules can be adjusted depending on the change in the nomenclature and the number of measuring instruments.

    6.15.4 Calibration schedules must be submitted to the metrological service performing calibration before January 15 of the current year.

    6.16 The procedure for receiving and registering a measuring instrument for calibration.

    6.16.1 Measuring instruments are accepted by the metrological service from the divisions of enterprises for calibration within the time limits established by the calibration schedules.

    Measuring instruments belonging to other enterprises and organizations are accepted within the terms specified in the contract for calibration work.

    6.16.2 Registration of measuring instruments accepted for calibration is carried out in a special journal by persons appointed by the heads of the metrological service.

    6.16.3 Submission of measuring instruments for calibration to the bodies of the State Metrological Service, state scientific metrological centers or other organizations is carried out in accordance with the terms of the concluded agreement.

    6.17 Registration of calibration results.

    6.17.1 The results of the calibration of measuring instruments are certified by a calibration mark affixed to the measuring instruments or a calibration certificate (Appendix B), as well as an entry in operational documents.

    6.17.2 The results of the inspection calibration are reflected in the calibration report.

    6.17.3 Protocols with the results of calibration of measuring instruments are kept until the results of the next calibration are obtained, but not less than one year.

    List of measuring instruments for topographic-geodesic and cartographic purposes subject to calibration

    General provisions

    This list applies to measuring instruments used in the performance of topographic, geodetic and cartographic works and subject to calibration in accordance with the Law of the Russian Federation "On ensuring the uniformity of measurements". This document was prepared by the Head Organization of the Metrological Service of Roskartografii - TsNIIGAiK in addition to the list of measuring instruments used in geodetic works and subject to verification.

    This list is intended for the metrological services of organizations and enterprises that carry out topographic, geodetic and cartographic work.

    Calibration work must be carried out in accordance with the methods and means of MI calibration, approved in the prescribed manner. As reference data, the list indicates the time intervals between two calibrations (MCI), which during the operation of the MI can be adjusted based on static measurement data, taking into account specific operating conditions and requirements.

    With the development of measuring instruments, the above list can be refined and supplemented.
