Verification of measuring instruments: the organization and procedure of

click fraud protection

in Russia for a long period of time there follows the practice in the field of metrology: the permissible limits established in only with relevant government regulations.Brewing the need for the relevant law in this area.This was done in 1993.Was the Law "On ensuring the uniformity of measurements."

Objectives The main objectives of this regulation:

  • protection of the legitimate interests and rights of citizens of the Russian Federation in accordance with the legislation in force in the field of measurement results;
  • assistance and support at the state level economic and scientific and technical progress by the introduction of standard units, the performance guarantee of the accuracy of applications of the standards;
  • create a favorable climate for the development of international relations;
  • formation of a unified system of standards for the smooth release, sale, operation, maintenance manufactured in Russia and imported from abroad means of measurement;
  • a gradual reduction of the measuring structure used in Russia to the world standards.

Verification of measuring 44-FZ

Let's examine this concept.Verification of measurement tools - a collection of all the actions that are performed by the State metrological service or other organizations of a similar profile.For the implementation of the activities of those agencies must have special permission and authority.Events organizations focused on conformity assessment measuring the statutory requirements.The main goal of the test is to determine the characteristics of the equipment, comparing them with the values ​​established by the regulations.The assessment carried out an opinion on the possibility / impossibility to use the specified documentation purposes.Calibration testing performed by an authorized body or organization, made with special metrological quantities.These parameters are determined experimentally.Verification is required for all new measuring instruments made by the relevant standards in service, as well as accessories, undergone repair actions.The need for the implementation of the activities covered by mandatory to use in the field of regulation to ensure standards (GROEI).Used in other areas of equipment is calibrated on a voluntary basis.

The competent authorities

calibration testing is carried out by a special accredited metrology services.Staff should be trained, which is issued at the end of a special diploma.Only after that employees can perform such specialized work.Non-state enterprises, unlike the state, and free to choose without restrictions body, which will be carried out calibration of measuring instruments.Organization and procedure of the assessment fixed at the legislative level.Based on the competition state and municipal authorities are obliged to enter into contracts for the implementation of the authorized bodies of the activity.In cases where the outcome of the assessment is positive, the corresponding certificate is issued, or apply a special stigma (there are other ways provided for by law).

Technical features

Technically calibration of measuring instruments - a procedure for comparing the physical quantity (in numerical terms), obtained with the help of the equipment under test with a reference value.Options, taking for a basis of comparison (reference), obtained as a result of multiple assessments serviceable high-precision instruments.At the same time there is a limit: the standard error is required to be at least three times less error passing calibration testing.In accordance with applicable law, such products may be subject to a primary, scheduled, unscheduled inspection and evaluation.

primary comparison

Initial verification of measuring devices is carried out for all devices, classified by type of production shipped, past repairs or imported from another country.There is a time limit of action produced evaluation.It is only valid within the approved model certificate for each device.Used two types of verification: sampling and each instance.The most common is the second option.Exceptions are not subjected to initial verification, can be a means imported from abroad in the framework of international agreements.Of the Treaty in this case, imposes the obligation to evaluate and award the international certificate for foreign manufacturers.Initial verification of measuring instruments is done on special checkpoints organized by specialized agencies.Most of these items for the convenience and time savings are directly on equipment manufacturers or repair shops.The results of such verification is valid for a certain time - period of recalibration.

planned evaluation

This calibration of the measurement (in operation or in storage) is performed in a strictly defined time intervals.For each industry developed their own special spaces in which you need to evaluate.For example, the calibration of measuring instruments for medical purposes is done more often than verification of roulette in cartography.This unused devices that are in a state of prolonged storage, subject to certain rules (integrity of seals, packing, storage in one place and so on. D.) May not be subject to evaluation.In carrying out the comparison host (the user) must provide verifiable funds in working order with full attached documents: passport, application instructions, the documents of the last calibration (if made) and all sets of tools, which are provided by the manufacturer.Government evaluators equipment required to conduct a full accounting of the results of their actions.The findings may be the basis for adjustments mezhproverochnogo interval.However, this hotfix is ​​possible only in exceptional cases and only with the consent of the State metrological service.The controversial issues arising from this situation, the final decision shall SSMC.In most cases, routine calibration of the measurement is made on the territory of the owner (user) of the equipment of the authority.Thus the right to choose their assessment belongs to the user, taking into account its production and economic opportunities.In the big cities can have a significant impact transportation equipment to the place of the assessment.Therefore, for example, calibration of measuring instruments in Moscow in some cases can be performed on the territory of the manufacturer or the user.

unscheduled evaluation

frequency of such verifications do not have a clear time frame.Indications for its implementation include the following cases:

- damaged stigma;

- lost calibration certificate;

- commissioning after long term storage;

- held reconfiguration or alignment;

- the occurrence of errors in the work, or as a result of impact.

inspection verification

The purpose of this evaluation is to identify the suitability of the unit under test for metrological control at the state level.Its results are reflected in the relevant act.Carrying out of such verification is not in full, provided that the verification procedure.
