1 Metrological examination of the technical specifications for product development

Terms of Reference - the original document for the design and construction of the industrial complex, construction of technical devices (devices, machines, control systems and so on. D.) Or conducting scientific research. TK sets the basic purpose, technical and performance characteristics, performance and quality of technical and economic requirements for future products, the necessary stage of development of design documentation and its composition, as well as specific requirements for the product. TOR usually consists of the following sections:

- The basis for development;

- Aim and purpose;

- Tactical and technical requirements;

- Technical and economic requirements;

- Requirements for the types of software;

- Special requirements;

- Stages of development (performance);

- The order of execution and acceptance;

- Application.

Metrological examination of TK is carried out in the following sequence:

1. Check the correct construction of TK. Check that all required sections and applications.

2. Evaluate the range of optimal parameters measured, the correct form of recording, the ability to measure the parameters of the production with the required accuracy by using existing or proposed means and methods of measurement, test methods.

Despite the fact that the expert-metrologist carefully, "is considering" the entire text of the TOR, the most attention he has paid to the "operational requirements" and the paragraph titled "Requirements for metrological support" in the "Requirements for the type of collateral." In the "tactical and technical requirements," identifies the main controlled parameters and initial requirements for the methods and means of measurement, monitoring conditions and product testing, its maintenance and repair. Here the examiner should draw attention to the fact that the developer should not use the phrase "no worse" ("no better"), "worse" ("better"), "do not have" (not "bigger") to quantify the requirements for parameters . Correctly in these cases, to use the words "no more" ("Still"), "a" ("less").

2. Analysis of the measurement in organizations.

. The results of the analysis of the measurement, control and testing in the enterprise, organization, association (the company) are the basis of:

- Proper prioritization in solving individual problems of metrological support and solutions to meet customer requirements in terms of functional characteristics of the product, the conditions of its operation, the introduction of zero-defect product manufacturing, ensuring the profitability of its production;

- Assessment of the measurements in the company for an official certificate of having the conditions necessary for the measurement, control, and test (for example, to obtain a license for the type of activity in the certification of production and (or) quality systems).

13. Summarized results of the analysis of the measurement, control and test facilities may be justification for the development of activities (sections) of metrological provision of federal target programs and other programs of metrological support sectors of the economy, regional programs of metrological support. On the basis of summarizing the results of the analysis of the measurements, monitoring and tests can be carried out work on marketing instrument-making products.

14. Analysis of measurement, control and testing company (association) should be carried out at all stages of the life cycle of certain products manufactured by the enterprise to meet the requirements of the Law "On ensuring the unity of measurements", consumer interests and market conditions.

For what purposes the analysis of the state of measuring instruments.

The procedure for the development and implementation programs of metrological support sectors of the economy, the most important scientific and technical problems. " On the basis of summarizing the results of the analysis of the measurements, monitoring and tests can be carried out work on marketing instrument-making products.

Analysis of measurements, control and tests should be carried out at the plant at all stages of the life cycle of certain products manufactured by the enterprise to meet the requirements of the RF Law "On ensuring the unity of measurements", consumer interests and market conditions.

Significant system state tests

The system of state testing serves as an important link feedback into a single system of state management of product quality, providing the necessary and accurate information about the quality. [1]

The system of state testing in the form as it is being formed, substantially expands both the notion of the state tests, which previously applied only to the acceptance tests, and the scope of use of the results of the state tests, which are currently already covered more than 6000 columns. [2]

The system covers all state tests, without exception means of measurement to be made (as a serial, and identity), and imports from abroad. [3]

The system of state testing is a reliable tool to ensure the production and exploitation of resources - measurement that meet the requirements of today. [4]

The system of state testing measures and measuring instruments consists of a set of rules and regulations, requirements and standards of scientific, technical, economic and legal issues, defining goals and objectives of the test, the organization and methodology of the tests, the order of registration, examination and approval of their results, as well as control the release of measuring instruments. [5]

The system of state testing of measuring instruments are constantly being improved. [6]

The system of state testing of measuring instruments has a significant impact on the improvement of the measuring equipment, it contributes to the effective use and comprehensive solution to the issues of metrological support of tests of other types of products. [7]

The system of state tests of measuring devices includes a set of rules and regulations, requirements and standards of scientific, technical, economic and legal issues, defining goals and objectives of the test, organization and methods of work on the test, the order of registration, examination and approval of their results, as well as control the issue of measurement. [8]

Creating a system of state testing in the country - a new business, there is still much to do to this system has become a reliable barrier formulation for the production do not correspond to the current level and unfinished products. [9]

The main provisions of the state tests are regulated by GOST 8.001 - 71 State system for ensuring the uniformity of measurement. [10]

It requires further improve the system of state testing. This mechanism is performing poorly: the instruments available to 15 - 20 years without the necessary modernization, about 20% of the measurements that have passed acceptance tests in a timely manner is not mastered by industry, maintenance of the state registry is carried out formally, belittled the role and responsibility of government commissions and institutions, is the parent of corresponding type of measurement. [eleven]

Created a system of government in the country of production tests, based on the organizational umbrella organizations on state tests approved by the ministries and departments, together with the State Standard of the USSR. In this state exam test centers on the quality of all the products keeps on fixed nomenclature, produced by enterprises of the country, regardless of their affiliation. [12]

State verification schedule

State verification scheme applies to all means of measurements of the physical quantity used in the country, such as the means of measuring the electrical voltage in a certain range of frequencies. By setting the size of the multi-stage procedure for the transfer of physical units of the national standard, the requirements for means and methods of verification, state verification schedule is a structure of metrological support certain types of measurements in the country. These schemes are the main centers developed standards and are made one guest GSI.

Calibration and adjustment of measuring instruments.

Gauge calibration - establishing the relationship between the testimony of measuring equipment (instrument) and the size of the measured (Input) value. Under the calibration process frequently understood reading the output value adjustment or display of the measuring instrument to achieve reconciliation between the reference value at the input and output results (including specified accuracy). For example, the calibration of a medical thermometer showing the temperature of the bath with 36,6 ° C results in the display 36,3 ° C, is to add 0,3 ° C. It does not matter whether this value is entered in the device memory or written on paper glued to the thermometer.

Define the terms: calibration, adjustment, calibration, verification schedule, test and control.

Test - determining one or more characteristics

products according to the established procedure.

The challenge tests - to provide a qualitative or quantitative

estimates of characteristics of the product, ie evaluate the ability

perform functions required in the given conditions. This problem is solved

is in testing laboratories, its solution is prepared

lenny test report indicating the product parameters.

Control - conformity evaluation by observation

tions and opinions, accompanied by corresponding measurements,

tests and calibration.

Define the term: metrological certification, testing and verification procedure measuring instruments.

Metrological certification of measuring instruments shall be imported or manufactured in the territory of the republic in single copies (not more than three of measuring by the applicant within one year) and used in the implementation of the state metrological control

Test instrumentation - a mandatory procedure, without holding that the entrepreneur does not have the legal right to carry out the manufacture, sale, use, import and export of these products. [Read more on http://gortest.su/proverka-izmeritelnyh-priborov/]

The role and tasks of the metrological examination

Metrological examination of the technical documentation is carried out by the analysis and evaluation of technical solutions in terms of MO (technical decisions relating to the measured parameters, establishing requirements for measurement accuracy, the choice of methods and means of measuring their metrological service).

The main objective of the DOE - to achieve efficiency Defense, perform the general and specific

requirements for DoD best practices and resources.

The specific objectives of the DOE determines the purpose and content of the technical documentation. When working with the technical documentation experts have to deal with many different problems. The main objectives of the DOE technical documentation and ways of their implementation are presented in Table 1, as required for its organization of the event. Tabular method of reflection important information, in my opinion, is the most convenient for perception and memory.

State supervision. Inspections during the design, construction, operation and maintenance of products.
