Verification marks are symbols applied to measuring instruments, devices, including additional ones. In some cases, stamps are placed on technical, certifying documents. Verification marks show: documents, measuring equipment have successfully passed the test, showing positive results. The safety of the stigma is an indicator of security. If during verification it is revealed that the verification mark has been violated, then there was unauthorized access.
Features of use
If verification marks have been established, sooner or later the time comes to redeem them. For this, other brands are usually used, designed in a special way.
Verification marks can be installed using various methods. The most common: percussion method, gluing, mastic. In addition to them, technologies are in use:
- electrochemistry;
- sandblasting;
- electrography;
- burning out.
The most accurate technologies are used for the manufacture of stickers, the removal of which is impossible without damage. Therefore, it will not be possible to transfer the verification mark from the equipment verified in the correct way to the untrusted one.
Rules and requirements
He talks about what verification marks should be, RosStandart. The metrological rules 50.2.007-2001 are devoted to the same. In the documentation you can find the requirements for the form of stamps, given instructions for applying labels.
You can use only such marks, whose drawing is clear and clear, understandable. A specific option is chosen, focusing on how much time passes between checks. It is important that the entire impression of the credential mark is maintained in good shape, readable without difficulty. And this, in turn, depends not only on the length of the interval between checks, but also on the conditions in which the device is used.
Where is it relevant?
Since verification marks are absolutely indispensable, manufacturing is relevant in metrological centers and institutes of metrology. Some legal entities include metrological services that also use stamps. There are even such individual entrepreneurs who have passed accreditation and received permission to work in this area.
Deciphering the verification mark allows you to get information about the date of the last test of the device and about who carried it out. In addition, a note is made by the federal authority responsible for metrology, the cipher of the State Scientific Research Institute of Metrology, the State Russian Center for Metrology and Legal Entities, and a unique symbol of the witness is printed. The date is indicated by the last two digits of the year in which metrological work was carried out.
Tag specifics
The sticker of the verification mark does not always contain only the information described above, many also have additional information. Some bureaus put symbols on which quarter, month the work was carried out. However, it is important to ensure that additional data does not interfere with the more important characters, in the first place - the image of the sign.
The identification of measuring instruments can be automated, which is achieved by indicating a special bar code. It can be used to encode data on previously performed calibrations. If the types of verification marks used allow the application of a bar code, it is considered preferable to use it in metrological work.
Protection: High
To minimize the likelihood of counterfeiting, it is necessary to use such stamps, for the protection of which the technology of holographic images was used. To put any horrible pictures will not work. The image first passes official approval by the state authority, only after that it is used to ensure security. In addition, complex ciphers of verification marks can be called an anti-falsification tool.
The marking requirements when it comes to an automated computer system are somewhat simpler. This advanced technology ensures the accuracy of reading information. Due to this, it is possible to reduce the amount of identification information. It is enough to indicate the series or number, this is enough for the car to check. However, you need to understand that only a correctly working IP can guarantee the compliance of all significant details of the checked mark and data in the database.
Identification using modern methods
Of course, the classic rubber verification mark is a good and reliable thing, but it's time to switch to more technologically advanced solutions. These were bar code stamped brands associated with electronic databases. The use of such a bundle minimizes the time for identifying characters and ensures the accuracy of the process without falsification.
Through special equipment, the automation system reads the identification symbol, from which it draws conclusions about the code of the company that checked the equipment and sets the date when the metrological check was carried out. In addition, the automatic system sets an individual cipher, determines some other parameters from which it can be concluded who exactly was responsible for the earlier verification. However, the use of an automated system at the enterprise should be carefully thought out to avoid problems from the state regulatory authority - it is known that officials can perceive violations even where the legal entity is not aware of them.
Features of installing different brands
If the mark is placed solely in order to prevent third parties from accessing the equipment, then there may not be an individual mark of a specialist responsible for verification. Such seals are needed to protect measuring instruments, automation for branding.
The mounting points of such seals, on which there is no verification mark at all, are selected based on how the measuring means should be protected. How much such fillings are needed is also determined by focusing on the particular situation.
Redeem wisely
Special brands have been developed, used exclusively for extinguishing. Usually they are made in the shape of a cross, which symbolizes the cessation of the previously set mark during verification. A cross mark is put, checking the measuring equipment, technical documents, certificates confirming the fact of the previous verification.
In some cases, the stamp is quenched by sticking a special label on it. If such a blanking method was chosen, then it is necessary to stick a strictly red mark, other colors are unacceptable.
Rubber stamp: specifics
When deciding in favor of a rubber stamp, a number of features must be considered. In particular, the forms allowed for use by different persons are strictly regulated. The list is as follows:
- round stamps can put GNMI, SRM;
- rectangular are placed on industrial measuring instruments;
- the square mark the operated, repaired measuring instruments.
Ciphers: specifics
If the verification is carried out by the State Central Museum, then two capital letters (Cyrillic) are necessarily present in the conditional cipher. It looks like this: AB, AB. If verification was organized with the involvement of the GNMI, then there is only one Cyrillic letter in the cipher. If the forces of IP, legal entities specializing in work with metrological equipment were involved, then the conditional code contains three Cyrillic letters. It looks something like this: AAB, AAB.
Individual entrepreneurs, metrological services receive their unique conditional codes in the framework of accreditation. Only after gaining the right to check the measuring equipment, you can count on your own code, which is then used in the work.
Legend: what else?
The individual character of the person who performed the verification is usually a letter. Some have been given Latin letters, while others have Cyrillic or even Greek. The usual Arabic numerals are used to indicate the month, but the quarter in which the verification was carried out is marked with Roman ones.
It is not so easy to produce equipment with which you can put verification marks. If such units are intended for use by GNMI, SRM, then you will have to go through a difficult procedure. Production of equipment is allowed exclusively centrally, under state control. To do this, create a special state order and organize a competition, in which they choose the company that offered the most favorable conditions. The authority responsible for this process is the Agency for Technical Regulation and Metrology.
Strict control: is it necessary?
The described difficulties associated with the features of the manufacture of equipment for the installation of the stigma were introduced not just for the sake of bureaucracy. It is important to consider all hallmarks and prevent falsification. For this, exclusively high-quality devices should be used in the work, which would be protected for the entire period from inspection to inspection.
It is quite difficult to control the situation if the stamps are established by technological, modern methods: electrography, electrochemistry, sandblasting. If one of these methods is used, then the quality of the obtained mark is controlled. The more perfect the technology, the more reliable the stigma will be, the less likely its falsification.
Subtleties of protection
Relative to other types of fillings, there are other difficulties. So, stickers are a fairly simple type of stigma in the population, but it is difficult to maintain its long time period without damage. It is necessary to carefully consider this so that the sticker is not spoiled by mechanical damage or aggressive substances.
The most dangerous are engine oil, alcohol-based components and gasoline. The manufacturer must carefully choose the materials for the production of stickers, so that the finished seals turn out to be durable and reliable, and during the next check, the data from them could be read without errors.
Hallmarks: there are different sizes
How big is the mark on the metrology equipment under test? It depends on the specifics of the tested equipment. The larger the object of control, the larger the seal can be delivered. In addition, much depends on the size of the equipment used to make the stamp. The larger the device, the larger the mark can be made, and vice versa.
Most often, the mark is made (dimensions are indicated in millimeters) with a diameter of 4 to 24 millimeters. If it is necessary to put a seal in the form of a square or rectangle, then the following size characteristics are selected: width within 4-24 mm, and length one and a half times greater.
Stigma: comply with the rules
It is necessary to apply stamps on the documentation, measuring means, observing the requirements established for this by the laws of our country. They apply the mark in such a way that, subject to the requirements and rules, the information would be easy to read.
The overlord has his own unique personal brand. It is complemented by an individual symbol. The mark cannot be transferred to other persons under any pretext. It is very strictly necessary to store and take into account the hallmarks used in metrological services and state authorities. To do this, usually choose one employee who is appointed responsible for the safety of the stigma. Appointment is made by special internal order.
Accounting Features
To ensure that everything is under control, a control print must be taken from each brand. Impressions are necessary for stickers. They are kept all the time while the brands are valid. If it turns out that the verification work was performed poorly, reading the characters and identifying the impression will help identify the responsible person responsible for this. The contractor is fully responsible for the accuracy and quality of the verification.
