METROLOGY RULES
State system for ensuring the uniformity of measurements
1.1 This document establishes the form and procedure for applying verification marks.
2.1 Verification marks are a sign applied to the measuring instrument, additional devices and (or) technical documentation and certifying that the verification of the measuring instrument was carried out with satisfactory results, as well as to protect, if necessary, the measuring instruments from any unauthorized access, including adjustment ( adjustment devices.
If it is necessary to cancel an existing verification mark, special verification marks are used.
2.2 Methods for applying verification marks can be as follows:
- pressure on the filling or special mastic,
— other methods (sandblasting, burning, etc.).
2.3 The verification mark must have a clear pattern that is maintained throughout the entire verification interval in relation to the conditions in which a particular measuring instrument is operated.
3.1 Verification marks must contain the following information:
— conditional code of the body of the State Medical Migration Service, State Scientific and Technical Center or the metrological service of a legal entity;
— the last two digits of the year of application of the verification mark;
- individual sign of the trustee.
3.1.1 If necessary, additional information can be placed in the stamp field, for example, the quarter or month of the year in which the measuring instrument was verified. In this case, the image of the sign applied using the stamp must remain clear.
3.1.2 For the convenience of automating the identification of measuring instruments, as well as accumulating information about the results of verifications, the verification mark may contain barcodes, if the method of its application allows this.
3.1.3 In order to increase protection against falsification, verification marks in the form of stickers can be equipped with a holographic image. The drawing of the applied image is approved by the State Standard of Russia.
3.1.4 In cases where the verification mark is used in conjunction with an automated information system that ensures an unambiguous correspondence between the listed information details and each applied verification mark, only an identification mark (for example, series, number, etc.) is allowed to be applied to the mark.
3.2 Brands designed to prevent unauthorized access to the units for adjusting the readings of the measuring instrument and automatic branding may not contain the individual sign of the verifier.
The installation locations of seals bearing verification marks and their number are determined in each specific case when approving the type of measuring instruments.
3.3 Extinguishing stamps contain a cross-shaped pattern indicating the termination of the verification stamp applied to measuring instruments and (or) technical documentation or verification certificate.
If the stamp is canceled by applying a corresponding sticker, it must be red.
3.4 When applying a verification mark in the form of a rubber stamp imprint, the following forms are established:
b) for metrological services of legal entities:
for measuring instruments released from production, rectangular; for measuring instruments in operation and after repair, square.
Examples of drawings of verification marks are given in Appendix A.
The assignment of conditional codes to metrological services of legal entities that use verification marks is carried out in the process of their accreditation for the right to verify measuring instruments.
3.6 The individual sign of the verifier is designated by one of the letters taken from the Russian, Latin and Greek alphabets.
3.8 The production of means for applying verification stamps for the bodies of State Migration Service, State Scientific and Technical Center and metrological services of legal entities is carried out in a centralized manner at enterprises determined based on the results of the competition by the State Standard of Russia.
3.9 The sizes of verification stamps are selected depending on the sizes of the devices used for stamping measuring instruments.
Recommended range of sizes of verification marks: 4; 6; 8; 10; 18 and 24 mm.
Rectangular and square verification marks have a width equal to the indicated diameters, and the ratio of length and width of rectangular marks is recommended to be 1.5:1.
4.1 Verification stamps confirming or canceling verification results are used by employees of the State Migration Service, State Scientific and Technical Center or the metrological service of a legal entity accredited for the right of verification, certified as verifiers in the manner established by the State Standard of Russia.
4.2 Verification marks are applied to measuring instruments and (or) technical documentation or certificates in accordance with the requirements stipulated by regulatory documents for the verification of measuring instruments, if the verification results are positive. The verifier applies the mark in such a way that it is located in the proper place and is clearly and easily legible.
4.3 Each verifier is assigned personal verification marks that have an individual sign of the verifier. Transfer of such marks to other persons is prohibited.
4.4 Storage and recording of verification stamps in the bodies of the State Migration Service, State Scientific and Medical Center and metrological services of legal entities that use verification stamps is entrusted to the responsible employee appointed by the head of the legal entity.
Stamps are issued to verifiers and accepted from them with a mandatory note in the journal (Appendix B).
4.5 From verification stamps that have an individual sign of the verifier, one print is taken (one copy of stickers is left). Prints (or corresponding copies) must be stored for the duration of the trust mark applied to measuring instruments and (or) technical documentation.
4.6 Responsibility for improper performance of verification work and non-compliance with the requirements of relevant regulatory documents lies with the relevant body of the State Metrological Service or the legal entity whose metrological service performed verification work (Law of the Russian Federation of April 27, 1993 No. 4871-1 “On ensuring the uniformity of measurements” ( Gazette of the Congress of People's Deputies of the Russian Federation and the Supreme Council of the Russian Federation, 1993, No. 23, Article 811).
5.1 When the measuring instrument gives incorrect readings or the verification interval is expired, the state inspector cancels the verification mark or cancels the verification certificate.
Verification marks made in the form of stickers are destroyed.
5.2 Cancellation is formalized by an act of any form. A copy of the act is sent to the State Migration Service at the location of the legal entity and to VNIIMS .
