1. 11. What types of work carried out in the public system of measurements.

State system for ensuring the uniformity of measurements - a system for ensuring the uniformity of measurements in the country, implemented, managed and controlled by the federal executive authority of metrology - the Federal Agency for Technical Regulation and Metrology (Rostechregulirovanie).

Activities to ensure the unity of measurements aimed at protecting the rights and legitimate interests of citizens, the rule of law and the economy by protecting against negative consequences of doubtful measurement results in all spheres of society on the basis of constitutional provisions, laws, government decrees and regulations (ND).

Ensuring uniformity of measurements carried out in the country:

at the state level;

at the level of federal bodies of executive power;

at the level of entities.

The purpose of the state system of ensuring the uniformity of measurements - the creation of national legal, regulatory, organizational, technical and economic conditions for the solution of problems to ensure traceability and the provision of all stakeholders to assess the possibilities to correctly perform the measurements.

The main tasks of the CIO:

development of optimal management of principles to ensure traceability;

organizing and conducting fundamental research to create a better and more precise methods and means of reproduction of units and the transfer of their size;

establishment of a system of measurement units and measurement scales, admitted for application;

Establishment of the basic concepts of the metrology, harmonization of terms and definitions;

the establishment of an economically rational system of state standards;

the creation, adoption, implementation and improvement of the state standards;

the establishment of systems (by measuring) the transfer of units from the values ​​of the state standards measuring instruments used in the country;

establishment and improvement of secondary and working standards, verification of complex installations and laboratories;

establishing common metrological requirements to standards, measuring instruments, measurement procedures, methods of verification (calibration) of measuring instruments and other requirements, compliance with which is a prerequisite for ensuring the uniformity of measurements;

development and examination of sections of metrological support of other federal and state programs, including programs for the creation and development of production of defense equipment.

1. 12. Analysis of metrological support to the pre-production stages.

It is to maintain and verify the TA organization in all its phases. The first (very responsible) step is the incoming inspection of incoming raw materials and components. Many enterprises treat him formally. Analysis of metrological support at this stage includes the establishment of proper organization of input control, including the optimal range of monitored parameters and security jobs means and methods of measurement, as well as relevant organizations to control the input requirements of GOST 24297-87 "quality inspection products." Special attention at this stage should be paid to the security of industrial sites, primarily jobs OTC instrumentation and suitability of their application. First of all, it concerns staples, calibers, designed for the enterprise and in service. In the analysis of metrological support of the manufacturing process is necessary to pay special attention to the state of technological tooling (dies, molds, technological tools).

At the same time check:

1. A passport;

2. compliance with the dimensions specified in the data sheets, drawings on technical equipment, the drawing size of the workpiece;

3. The actual size for technical equipment;

4. appearance.

During the TP, such as annealing, tempering, hardening, normalizing, drying of products necessary to control temperature conditions. When checking of metrological support of technological modes of control must be installed properly reflected in TD controlled parameters and measuring instruments, application of measuring method chosen temperature control.

13. The main tasks of the metrological examination of technical documentation The main goals and tasks of metrological examination of design and technological documentation to date regulatory document defines MI 1325-86 "Guidelines. GSI. Metrological examination of design and technological documentation. The main provisions and objectives." In accordance with DOE design and technological documentation - analysis and evaluation of technical decisions on the choice of parameters to be measured, setting standards and ensuring the accuracy of measurements methods and means of measuring the processes of design, manufacture, test and use products.

The reasons stated in the definition of the target installation are obvious: the low level of metrological study makes it impossible to control the parameters of already manufactured products (complex parts, assemblies, process equipment and, most often, measurement). From a formal point detection nekontroleprigodnosti production should be stopped, as in the case of uncontrolled release of products with parameters a risk of improper functioning of the consequences of a possible material losses, accidents and disasters.

Control solutions of designers and engineers, in terms of the ability to measure the parameters of the designed products and processes, always held on a mandatory basis. Formally, such control was a direct obligations of developers, as well as the responsibility of supervising and approving the documentation of persons. Objectively, this process is not metrological examinations due to lack of a systematic approach and a lack of metrology training of designers and engineers.

The effectiveness of metrological examination of the more than before it started, as a plan of metrological error and easier to eliminate the consequences if detected early. The fuller the metrological examination carried out, in greater detail worked out its task, the higher the efficiency and the further development of the documentation will be carried out competently metrological provision. Therefore metrological examination should begin to develop the basic design and technological documentation and expose her to all the documents, starting with the application development, technical project and technical proposal. On the stage of the examination "pre" documents can assess the possibility of controlling the parameters of the future product universal measuring instruments, clarify the prospects of metrological support future production.

Metrological examination of design and working documentation (technical design, assembly drawings, explanatory notes, specifications, programs, and test procedures) is characterized by the fact that there are new concrete tasks and challenges given at earlier stages acquire a complete form.

The appearance of the first standard GOST 8.103-73 "GSI. Organization and procedure of metrological examination of design documentation" recorded a need for institutionalization of the DOE as a specific event and attraction of specialists (expert metrologists) to solve complex problems. Currently, there are "Guidelines" MI 1325-86, the ideology of which is entirely borrowed from the canceled GOST 8.103-73. This regulatory document was not feasible due to incorrect setting goals DOE documentation. The new LP preserved almost all the tasks of the previous standard. Although the need for metrological examination of design, technological and research documentation is beyond doubt, conduct it in accordance with MI 1325-86 is difficult, and "in full" - is impossible.
