On the application of MDS 12 46.2008. Regulatory and methodological documents

31.10.2019

The conformity of the manufactured product with the design documentation is based on the correct choice of the limiting parameters of the product, their permissible deviations and the choice of technical means that provide these parameters. To ensure these factors, general

for design and technological documentation, metrological control is used. Metrological control - verification of compliance with metrological provisions, rules and norms in the documentation, clearly regulated in the current regulatory and technical documentation.

Accounting for metrological provisions in the design documentation requires specific knowledge from the performer. Developers of design documentation are often poorly oriented in matters of metrological support. As a result, new developments do not pay due attention to the issues of unity and the required measurement accuracy. GOST 1.25-76 establishes: “The metrological support of the national economy is understood as the establishment and application of the scientific and organizational foundations of technical means, rules and norms necessary to achieve unity and the required accuracy of measurements.” This goal is served by the standards of the State System for Ensuring the Uniformity of Measurements (GSI). The unity of measurements is such a state of measurements in which the measurement results are expressed in legal units, and the measurement errors are known with a given probability.

In addition to metrological control, which is carried out at enterprises, there is a metrological examination of design documentation. This is a research process with the aim of analyzing and evaluating technical solutions for the selection of parameters to be measured, the establishment of accuracy standards and the provision of methods and measuring instruments. If in form metrological examination can be represented as a control process, then in content it is a set of interrelated organizational, methodological and technical measures. The goals of metrological examination are set out in GOST 8.103-73. Metrological examination of design documentation is usually carried out after metrological control.

Metrological control of technical documentation covers a number of fundamental issues, the solution of which improves the quality of the manufactured product. It ensures product quality in the most economical way, eliminating direct damage due to inaccuracies in design and technological documentation. The cost-effectiveness of quality is achieved by applying

application of optimal indicators of the measured parameters of the product. Metrological control begins with the identification of the measured parameters to be controlled. This is done by analyzing and determining the influence and place of each parameter in the overall design and operation of the product. Metrological control generally solves the following issues.

1. Consideration of the possibility of replacing qualitative requirements (if any) with requirements for physical quantities. It is advisable to replace organoleptic control with the requirements for physical quantities verified by measurements. For example, the requirement “Deep sinks on treated surfaces are not allowed...” is replaced by a requirement for the size of sinks and their number per unit area; the requirement “Mount the bracket vertically...” is replaced by the requirement for angular deviation, etc.

2. Checking the correctness of the expression of requirements, excluding the possibility of their different interpretations. It is recommended to use standard terms to express technical requirements. For example, the requirement “Shaft runout no more than ...” is replaced by the requirement “Total radial runout of surface A relative to ... no more ...”, the requirement “The solution is prepared by mixing component A and component B in a ratio of 1: 2” is incorrect, so how unclear what ratio is meant: masses or volumes.

Specific terms subject to the possibility of different interpretations should be defined or explained at the first mention in each document (in brackets, footnote, reference appendix). Reference to a specific standard allows for unambiguous interpretation of the technical requirements and applicable parameters. Metrological terminology is specified in GOST 16263-70, the correctness of the names of physical quantities - in GOST 8.417-81.

3. Analysis of the sufficiency of the range of controlled parameters that ensure the optimal quality of the product.

The proposals of the person conducting the metrological control on the adequacy of the requirements for the product are in the nature of recommendations (their consideration by the developer is desirable, but not mandatory). The exception is the metrological control of documentation for measuring instruments and test equipment

test equipment. In these cases, taking into account the proposals of the person conducting the metrological control is mandatory. It is expedient to introduce proposals for identifying new parameters to be measured in the design documentation at the early stages of development so that they can be implemented at subsequent stages.

4. Consideration of the possibility of reducing the range of measured parameters that reduce the cost of control. For example, analysis of the measurement of a particular parameter included in a complex parameter may reveal that a particular parameter is also measured in the process of measuring the complex parameter, so its separate measurement may not be performed. An analysis of the test conditions of the product may also reveal that subsequent tests with a lower mode can be canceled, since the first tests were carried out at higher modes, etc.

5. Checking the substantiation of the nomenclature of the measured parameters. The validity of the choice of measured parameters is checked by analyzing the research work preceding the development of the product, the results of experimental work and testing of prototypes. In the absence of justification, the inspector proposes to change the nomenclature or accuracy standards of the measured parameters.

6. Checking for tolerances of the parameters to be measured. The developer establishes the allowable deviations based on functional and economic considerations and taking into account the possibilities of their practical implementation. For example, the requirement "Deviation from flatness is not allowed" is not achievable, since it requires an ideal plane, so the requirement is formulated as follows: "Deviation from flatness is not more than ...".

The correct choice of accuracy standards ensures the quality and performance of the product and the economic performance of manufacturing. Accuracy standards allow you to select measuring instruments by accuracy class and measurement technique.

Metrological control checks designs in which it must be possible to measure the specified parameters of the product. To do this, the possibility of access to all measuring points is checked. If there are built-in measuring instruments, you need to make sure

whether it is possible to verify them during operation. If access to them is difficult, the expert can make suggestions for improving the design of the product. The measurement error is influenced by the properties of the material, the quality of the measured surfaces, etc. The rigidity of the measured element, its linear expansion at different temperatures, as well as surface properties (roughness, deformability, etc.) can significantly affect the measurement of the element.

The solution of metrological issues in new developments is carried out under the methodological guidance of the workers of the metrological service. The direct participation of the metrologist in the development is not necessary and is not practiced. A good result is the metrological control of design documentation, when the original document is developed and the main metrological issues are agreed with specialists in advance.

If metrological control is not carried out as an independent stage, then it is combined with normalization control of design and technological documentation. Normalization control is usually carried out by designers or technologists, and sometimes by metrologists. The executors of metrological control are specialized standard controllers of standardization services or employees of metrological services who have undergone appropriate training.

Metrological control of the terms of reference evaluates the completeness and clarity of the formulation of requirements for the parameters of the product being developed in terms of ensuring the possibility of their measurement with the required accuracy under specified conditions. Evaluates the validity of the requirements for metrological support of development, manufacture, testing and operation.

The metrological control of the explanatory note and the technical (draft) project is aimed at the following: substantiation of the nomenclature of the measured parameters; accuracy standards for measuring parameters, taking into account the specified requirements for the reliability of measurements; justification and assessment of the testability of the design (the ability to access the measurement elements, the sufficiency of control points - sockets, connectors, etc.); substantiation of decisions on the development of a methodology for performing measurements of the main parameters, decisions on the verification of built-in measuring instruments; analysis of the completeness and validity of the planned

works on metrological support at the stage of working documentation development.

Metrological control of technical conditions (TS) is aimed at carrying out the following works: analysis of the sufficiency and rationality of the range of measured parameters (compliance with the technical specifications, standards, etc.); assessment of the correctness of the formulation of the requirements for the parameters and the completeness of the requirements sufficient to ensure the accuracy of measurements; determination of permissible levels of dangerous and harmful factors created by the product; verification of compliance with the requirements of current standards governing the types of tests, acceptance rules, etc.; verification of control methods (tests, measurements, etc.); analysis of established measurement accuracy standards, test methods, etc.

Metrological control of the program and test methods (PM) is aimed at the following: analysis of the rationality of the nomenclature of parameters measured during acceptance, acceptance, periodic tests and during the operation of products; analysis of the content of the requirements for the measured parameters; checking the availability of test procedures for all technical requirements. If there are special measuring instruments used in the test, the fact of their metrological certification is checked.

When carrying out metrological control of drawings, the following operations are carried out: check the correctness of the textual requirements of the drawings; evaluate the sufficiency of the nomenclature of drawing requirements: requirements for all product parameters that affect the performance of their functions (dimensions, shape and location deviations, surface roughness and hardness parameters, coating thickness, etc.); analyze the rationality of the established system of requirements of the drawing regarding the control of the product. The drawings specify not only directly measured parameters, but also parameters that relate to manufacturing technology. These parameters are set, as a rule, by technologists, and they are the result of joint work with designers; evaluate the testability of the product. Product control must be provided by measuring instruments of general use and only in extreme cases by non-standardized measuring instruments.

If non-standardized measuring instruments are used to control the product, then the presence and content of the technical description, operating instructions, passports, instructions for checking these measuring instruments are checked.

When carrying out metrological control of working technological documentation, the following is carried out: check the correctness of the expression of requirements for controlled parameters; evaluate the rationality of the range of measured parameters; check the availability of measurement accuracy standards; establish the availability of control methods for all requirements of technical documentation; check the completeness and correctness of the requirements for measuring instruments; evaluate the compliance of the measurement accuracy indicators with the specified requirements. If it is difficult to ensure the specified measurement accuracy, the possibility of expanding the tolerance for the controlled parameter together with the developer is considered.

8.1 Compulsory metrological control

In accordance with the provisions of international documents, it is recommended that Type Approval Authorities, in agreement with the applicant, take into account the test results obtained by other national authorities without re-conducting these tests.

The notified body, at its own discretion and under its own responsibility, may accept the results of tests performed by the applicant for the type presented and reduce the scope of its tests accordingly.

8.3 Initial verification

Initial verification may be carried out by authorized personnel in accordance with national legislation.

Primary verification should not be carried out until the compliance of the instrument with the approved type and / or the requirements of this standard has not been established. A copy of the balance must be verified during installation and preparation for use at the site of the forthcoming operation, except in cases where the balance can be easily transported and installed after the initial verification.

Initial verification may be performed at the manufacturer, at the site of use, or at any other location if:

a) for the transportation of scales to the place of operation, dismantling of the scales is not required;

c) commissioning at the place of use does not require assembly or other technical installation operations that affect the characteristics of the balance;

c) the instrument is set to gravitational acceleration at the place of use of the instrument, or if the instrument is insensitive to changes in gravitational acceleration.

In all other cases, tests are carried out at the place of use of the instrument.

If the balance is sensitive to changes in gravitational acceleration, then verification can be carried out in two stages. The second stage includes all checks and tests, the results of which depend on the gravitational acceleration. At the first stage, the remaining checks and tests are performed. The second stage is carried out at the place of operation of the scales.

Instead of an operating location, a gravity zone or an operating zone where the instrument complies with national or regional gravity requirements may be defined.

8.3.1 Compliance

The declaration of conformity with the approved type and/or the requirements of this standard shall include:

A statement about the correct operation of all devices, such as zero-setting devices, tare devices and computing devices;

Statement on the material and design of the balance in view of their metrological significance;

Confirmation of module compatibility if a modular approach is chosen in accordance with 3.10.2;

List of tests that have been carried out.

8.3.2 Visual inspection

Before testing, the instrument is subjected to a visual inspection in order to:

Acquaintance with metrological characteristics, that is: accuracy class, , , ;

Identification of the software, if any;

Identification of modules, if a modular approach is applied;

Checking the presence of mandatory inscriptions and places for verification and control marks.

If the place and operating conditions of the balance are known, it is recommended to check whether they correspond to the required operating conditions of the balance.

8.3.3 Tests

Tests are carried out to verify compliance with the following requirements:

3.5.1, 3.5.3.3 and 3.5.3.4: error of indication [see A.4.4-A.4.6 (Appendix A), five loading values are usually sufficient, selected loadings should include if only 100 mg];

4.5.2 and 4.6.3: accuracy of the zero-setter and tare device [see A.4.2.3 and A.4.6.2 (Annex A)];

3.6.1: repeatability [see A.4.10 (Appendix A), third paragraph];

3.6.2: non-central load application [see A.4.7 (Appendix A)];

3.8: response [see A.4.8 (Appendix A)]; on instruments with a digital display, the test is not carried out;

4.18: tilt for mobile scales [see A 5.1.3 (Appendix A)];

6.1: sensitivity of non-automatic balances [see A 4.9 (Appendix A)].

In special cases, such as unusual design, questionable results, or if indicated in the relevant type test report, other tests may be carried out.

The Type Approval Authority may, in special cases, require the applicant to provide test loads, test equipment and personnel (see 3.7).

For all tests, as marginal errors, the limits of permissible error established during the initial verification are taken. If the balance after the initial verification must be sent to another place, then the change in the acceleration of gravity must be taken into account. For example, performing the second stage of the primary verification of the scales at the place of operation (after adjustment) or introducing a correction factor for the acceleration of gravity into the balance (at the place of operation), during the initial verification not at the place of operation.

8.3.4 Marking and protection

In accordance with national legislation, the results of the initial verification are confirmed with a stamp of verification. The stamp may indicate the month or year of the primary verification or the date of the next verification. National legislation may establish measures to protect components, the removal or reconfiguration of which leads to a change in the metrological characteristics of the balance, if the fact of intervention may remain unnoticed. Provisions 4.1.2.4 and 7.2 must be observed.

8.4 Subsequent metrological control

Subsequent metrological control may be carried out by authorized personnel in accordance with national regulations.

8.4.1 Subsequent verifications

During subsequent verifications, as a rule, only the control and tests specified in 8.3.2 and 8.3.3 are carried out, while the limits of permissible error are set as for the initial verification. Verification marking and protection may be made in accordance with 8.3.4, indicating the date of the next verification.

8.4.2 Supervision during operation

Surveillance during operation, as a rule, is carried out only in the form of controls and tests in accordance with 8.3.2 and 8.3.3. The limits of permissible error are set, doubled in comparison with the primary verification. The verification and protection marks may remain unchanged or may be updated in accordance with 8.4.1.
