In the third place, they carry out repairs of systems and measuring and automation equipment that lack operational reserve and the rest.

Verification of instrumentation and automation equipment

Verification is understood as a set of operations carried out to establish compliance of the metrological characteristics of measuring instruments with GOSTs or the technical conditions of the manufacturer.

Verification of measuring instruments, like other forms of metrological supervision, is regulated by state standards.

Metrological supervision in our country is carried out by the state metrological service of Gosstandart and departmental metrological services through verification of measuring instruments, metrological audit and metrological examination.

Verification, depending on the purpose of the measuring instruments being verified, can be state and departmental.

Measuring instruments used by departmental metrological service bodies as exemplary ones are subject to state verification at enterprises; owned by the enterprise and used as a model by the state metrological service; measuring instruments used after repairs performed for third parties; used for measurements related to accounting for material assets, mutual settlements, protecting workers' health and ensuring labor safety and harmlessness.

Measuring instruments that are not subject to state verification are subject to departmental verification.

Verification is carried out only by metrological service bodies or organizations that have a registration certificate for the right to verify specific means measurements.

A registration certificate for the right of verification and for the right of repair is issued to the territorial bodies of Gosstandart based on an application from the enterprise. Attached to the application: a copy of the regulations on the metrological service of the enterprise, approved and agreed upon in in the prescribed manner; a copy of the order appointing the chief metrologist of the enterprise; a certificate from the enterprise about the presence of qualified personnel who have the right to carry out repairs and verification, about the availability of premises, exemplary measuring instruments, documentation, diagrams.

After checking the certificate, the territorial body draws up an act and issues a certificate for the right to repair and verify the measuring instruments specified in the certificate for a period of 5 years. The certificate indicates the right to carry out repairs and verification only for oneself or for oneself and third parties.

A change in the certificate of nomenclature of measuring instruments for the right to repair and verification is issued on the basis of a newly submitted application in the same manner.

Persons who have undergone special training and passed exams in educational institutions Gosstandart, who have passed external exams in the state metrological service bodies, which are entrusted by Gosstandart with conducting certification of verifiers; who have passed the exams of the commission formed by the head of the enterprise with the participation of a representative of the state metrological service body, according to programs agreed upon with this body.

An enterprise that does not have a registration certificate is served by the basic metrological body of its industry, or submits measuring instruments for verification to the state metrological service. When sending measuring instruments to these authorities, a passport for them, a description, and the latest verification certificate are presented.

When verification is carried out by metrological service bodies at an enterprise, the latter provides the premises, equipment and support personnel necessary for verification. The presented equipment (verification installations, standard measuring instruments, etc.) must be stored by the enterprise under the seal of the metrological service authorities and used only with their permission.

Measuring instruments must be subject to primary periodic, extraordinary and inspection verifications.

Primary verification is carried out when measuring instruments are released into circulation from production and repair.

Periodic verification is carried out during the operation of measuring instruments and storage at certain verification intervals.

The frequency of verification is established: for measuring instruments subject to state verification by Gosstandart or the state metrological service body; for measuring instruments subject to departmental verification by the chief metrologist or the head of the departmental metrological service.

When establishing frequency, the stability of readings, operating conditions, and the degree of load on measuring instruments are taken into account. For example, at food industry enterprises, measuring instruments in use are verified, as a rule, once a year. Potentiometers, bridges, electrical measuring instruments are checked every 6 months.

The timing of verifications is displayed in annual calendar schedules separately for measuring instruments submitted to departmental bodies of the metrological service, separately to state ones. Schedules are coordinated with the heads of these bodies.

Calibration intervals for measuring instruments in storage are:

a) for measuring instruments received for storage after release from production, no more than the warranty period;

b) for measuring instruments that have been in operation, no more than double the verification intervals established for similar measuring instruments in operation.

Measuring instruments located on long-term storage, may not be subject to periodic verification. In this case, verification is carried out before installation.

Extraordinary verification is carried out:

1. During operation or storage, regardless of the timing of periodic verification, if necessary, ensure the serviceability of the measuring instruments;

2. When commissioning imported measuring instruments;

3. When adjusting calibration intervals;

4.When installing measuring instruments as components after half the warranty period;

5. If the verification mark, seal is damaged, or the document with the registration of the last verification is lost;

6.When commissioning directly from the warehouse after storage or after transportation.

Inspection verification is carried out to establish the serviceability of measuring instruments during metrological audits at enterprises, warehouses, and bases.

A metrological audit is carried out by the state metrological service to determine the compliance of measuring instruments and measurement techniques used at the enterprise with modern requirements.

Enterprises carrying out repairs, storage, and operation of measuring instruments are subject to audits. At the same time, enterprises carrying out operation must check: the presence technical documentation, where the requirements for measuring instruments are specified; availability of means and methods for measuring technological processes, quality control of products, accounting material assets etc.; correct installation of measuring instruments, their installation, use; compliance with operating conditions; serviceability; organization of the metrological service (structure, availability of personnel, their training, availability of equipment, premises, compliance of the work performed with the registration certificate); availability and correctness of documentation, its coverage of all measuring instruments “in operation; availability of exemplary measuring instruments, their condition and application in accordance with the requirements of regulatory documents; implementation of proposals given during a previously conducted audit.
