Calibration and calibration marks aretechnical devices, the main purpose of which is to leave an imprint of the stamp on a metrological device suitable for operation, on any additional equipment or on any technical documentation.
Why put a stigma
The purpose of applying the calibration mark is:
- The certificate is that the proven metrological means of measurement and instruments have the necessary technical characteristics, which are prescribed by them according to their GOST.
- Mark exceptions when it is necessary to access measuring devices to regulatory devices.
- Used for sealing devices, equipment or measuring instruments that for some reason are not suitable for further use.
- Also used to cancel the previous stigma. For this purpose, special annihilating stamps are used.
It is also important to note that when applyingThe imprint of the calibration stamp should be very clear, and it is also important to ensure that it remains on the instrument for the entire period during which it is permitted to operate this measuring instrument.
Application Methods and Information
Currently, there are several methods that are used to apply a stamp to a measuring instrument.
- The first method of application - shock.
- The second method of application is based on the pressure exerted on the seal, or by applying a special substance - mastic.
- The third method is applying the stamp with decal sticker.
- The fourth method of applying a calibration mark is electrophotographic.
- There is also an electrochemical and other ways of applying the stamp to the device or documentation.
Each stamp contains the following information:
- The sign K is used to identify the stigma in the Russian calibration system.
- Next comes the conditional cipher of the calibration stamp, which carries information about the accrediting body that has inflicted this stamp.
- You must specify the last two digits of the year in which the stamp was applied.
- The last thing that contains the stamp is an individual sign of the calibrator.

These postulates establish the rules of storage,manufacturing, cancellation, application of the stamp, which are used by the metrological services of legal entities entitled, that is, accredited to apply this stamp. These rules apply only to a calibration stamp, which is applied by a calibration specialist, then by a calibrator to a measuring device or technical documentation. Also, this stamp, if necessary, can be applied to additional units and measuring devices.
Notes on stamping
GOST calibration mark or the rules have several points. In one of these points concerning the information carried by the stigma, there are several notes on its content:
- If necessary, the stigma maycontain such additional information as the quarter or month of the year when the stamp was put, that is, when this instrument was accredited, but the imprint of the print should not be violated.
- The annulment stamp must be made in the shape of a cross, and its application means that the effect of the calibration stamp is canceled and the device is unsuitable for further use.
- The stamp that is intended to excludeAny measurement device from the regulation control unit may not carry an individual sign of the calibrator, but in this case, it is necessary to apply an additional stamp containing this sign.
- Условный шифр аккредитующего органа должен be denoted by two uppercase capital letters of the Russian alphabet - AB, AB, etc. If the mark is applied by the metrological service of a legal entity that has the right to apply such a mark, the cipher must be made in the form of three letters - AAB, AAB, etc.
Production
It is important to start with the fact that the productiongauge stamps according to the rules of metrology is carried out by the RSC Research Center, that is, VNIIMS. It is also important to know that the development of new types of stamps for each type of measuring instrument is carried out on the basis of proposals received from accrediting bodies, as well as from the metrological services of legal entities that use these devices.
Development of drawings that are appliedcalibration stamp, also deals with VNIIMS. It is important to note that the acquisition or manufacture of calibration stamps, each accrediting body or the metrological service of a legal entity, carries out in its own right. VNIIMS, on the other hand, is engaged in assigning an individual cipher to each accrediting organization or metrological service, which is going to use the stamp. For this you need to make and submit an application to this organization.
Using
The documentation spelled out the rules for the use of the stigma.
- Only the calibrator who received the certificate can use the calibration stamp.
- It is important to note that the application of the calibrationstamp on any measurement device or document is carried out strictly in accordance with the established rules, which are prescribed in the technical and regulatory documentation for each instrument.
- Imprint can be carried out only onthe measurement tool, which, after passing the inspection, gave exactly those results that the customer required, that is, the accrediting body or the metrological service of the legal entity.
- One of the important points is that each calibrator has several stamps that are assigned to it in a strictly individual way, and the transfer of any of these items is strictly prohibited.
Stamp storage
In addition to the above rules, this document also clearly establishes the rules regarding the storage of the stamp.
- Первый пункт повествует о том, что хранение, а Also, the account of this device in the metrological service should be kept by one responsible person, the appointment of which is independently carried out by the leadership of this legal organization.
- Responsibility for the safety of each stamp, as well as for the clarity of the application of each print on any device or equipment, or paper, lies directly on the calibrator.
- One of the important rules is that from eachgauge stamp, which has an individual sign, put up one print. It is necessary to store these prints as much time as the validity of the stamp from which it was made lasts.
- If you violate any of the rules that are spelled out in this document, all responsible persons will be punished, which is also established by this document.
Mark of trust
Verification mark, as well as calibration,is a mark that is applied to the equipment or instrument, or documentation. The presence of this sign on the device indicates that it has successfully passed the verification and can be used in accordance with regulatory and technical documents. Also, this stamp is applied as a protection against unauthorized interference with the device using an adjusting device.
The methods for applying this stamp are the same ashave a gauge. Using this sign, you can confirm or cancel the test results of this device. The person who applies the mark - the attorney must do so in such a way that the sign appears in the required place and is also easy to read. Just as in the case of the calibration stamp, each verifier has a number of verification prints assigned to him, each with an individual sign. He is also prohibited from transferring any stamp from this list to other persons. Storage and accounting of these signs is conducted by the responsible person chosen by the authorities of the organization. The issuance of the stamp of the witness and return it back into the hands of the responsible person must be accompanied by mandatory signatures.
