THE MEASURING CHANNELS CALIBRATION IN THE INDUSTRY

The trend of development of measuring equipment in particular measuring systems and technological processes leads to the need of measuring the temperature without dismantling the primary transducers and stopping the technological process in a very wide range and with high accuracy. The choice of methods and means of measurement depends on such factors as the value of measured temperature, necessary accuracy of measurement, conditions of measurements, and operation of the investigated object. The topicality of the problem is that industrial metrology operates the temperature measuring systems, transducers of which are deployed in such a way that their dismantling is impossible due to the specifics of the process or dangerous for operators’ life (nuclear power plants). Such measuring systems, due to the specifics of their application, are not metrologically provided in the periods between major repairs of controlled objects, thus violating the unity of measurements.

THE ENHANCEMENT OF METROLOGICAL SUPPORT THE COATING THICKNESS MEASUREMENTS

The article shows an improved hierarchy scheme in the field of coating thickness measurements, which was revised due to inclusion to Federal Information Fund for Ensuring the Uniformity of Measurements more than a hundred new types of Russian and foreign thickness gauges based on of different operating principles. The range of measurements has expanded and accuracy has been improved. It is shown that about 40 % of the approved types of thickness gauges are measuring instruments of foreign production. For responsible groups of materials (nickel on steel and nickel on bronze), only foreign coating thickness gauges are used. To improve the unity of measurements of the coatings thickness, it was necessary to expand the measurement ranges of the reference measuring standards and thickness gauges from 0 to 120 000 microns, as well as the introduction of new measuring standards borrowed from other hierarchy schemes. The article provides the necessary reference measuring standards and thickness gauges, methods for transmitting a unit of length, measuring ranges and measurement errors.

Colorimetric research of self-luminous objects in software and hardware environments by the method of multidimensional scales implementation

It is shown that the issues of metrological traceability for extended self-luminous objects with a wide range of brightness have not yet been resolved, since the rank scales of embedded systems are used for processing digital images. For such scales, there is no “fixed” unit, which does not allow you to get reliable results and ensure the unity of measurements. An experiment is described to evaluate the accuracy of determining the intensity (coordinates) of the color of self-luminous objects. In terms of repeatability and intermediate precision compared to the reference measurement method, the color and chromaticity coordinates of self-luminous objects (reference samples) were determined by their multiple digital registration using technical vision systems. The possibilities of the developed methodology for colorimetric studies in hardware and software environments from the point of view of constructing a multidimensional conditional scale are determined.

Training in metrology sphere for machine building

In order to meet the requirements for quality management of machine-building products and metrological support, the company analyzed the existing standards for confi rming the consistency of requirements. Federal state educational standards of higher education of two levels (bachelor’s degree and specialty) of the mechanical engineering profi le (ensuring the unity of measurements (GSEEI) and the professional standard of a metro specialist) were selected for the analysis. The obtained results are used in the implementation of term papers. It is recommended to cover issues related to measuring devices and automatic control devices in related disciplines, and to include the topic "Main areas of activity in the fi eld of metrological support of the enterprise".

Metrology

The basic provisions of theoretical, applied and legislative Metrology are stated. Examines the theoretical foundations and applied problems of Metrology at the present stage, the historical aspects and provisions of the Metrology of nanotechnology and quantum processes as a special kind of measurement of physical quantities. The main provisions of the Federal law of June 26, 2008 № 102-FZ "on ensuring the unity of measurements"are presented. It corresponds to the Federal state educational standard of higher education of the last generation. For students of higher technical educational institutions studying on technical specialties, as a textbook on General professional and special disciplines, as well as for persons interested in measurement and metrological support.

The Effective Mistake in Iran Fiqh and Jurisprudence

The effect of mistakes on contract depends on certain conditions of which the most salient one is the fundamentality of mistakes. Magistrates must refer to contract parties' intentionsto identify the domain of the fundamental mistakes and their effects on the contract. Is the domain of the effective mistakes limited to the subject and important characteristics of the contract parties? Or can we find a unity of measurements among the characteristics of mistakes causing nullification, which incorporate all or at least most of the proofs of mistakes causing nullification? Why do in some cases, mistakes result in nullification and in others the cancel right and in some other ones no effects in contracts? The civil law, in articles 200 and 201, limits the domain of mistakes to "the contract itself" and "the important feature of contract parties". If we consider the base of the mistake effectsitsfundamentality, the mistake domain includes any mistakes in all basic elements of contracts which are the main reasons for making the contracts and mutual consent. Its condition is that the description of fundamentality is clearly or implicitly mentionedin the contract. Also the extent of effect of mistakes in contracts, depends on the importance of mistaken element in the opinions of contract parties. Some of the elements of the contract are related to mutual consent and mistakes in them result in problems in intention and nullifying the contract. Some other elements are not related to mutual consent and they are not in the domain of intention of the contract. If mistakes in them comes to the domain of mutual consent, naturally it leads to the authority of cancelling the contract.

Interstate Standard on Measurement Assurance of Occupational Safety (GOST 12.0.005-2014)

An experience related to fixing of uniform requirements to metrological support in the labor safety area in Eurasian countries using interstate standardization procedures is considered. The approaches to ensuring the unity of measurements realized in the interstate standard during a control process for parameters determining a labor conditions status from a labor safety position are discussed.

Ensuring the uniformity of measurements of parameters of vibration during the technical operation of aircraft

In this article we are talking about how to ensure the unity of measurements of vibration parameters in the technical operation of aircraft. In air transport, the main controlled parameters of vibration in flight are vibration speed, vibration acceleration or vibration overload. They are particularly informative for aircraft with turboprop engines, as well as helicopters, which – because of the design features-the vibration is much higher than on aircraft with turbojet engines.

Certification software special SI air transport

In order to implement the provisions of the Federal law No. 102-FZ and the regulations of the state system of ensuring the unity of measurements on the basis of the metrological service in the Federal state unitary Enterprise GosNII GA test laboratory software SI and information and measurement systems (IIS). In terms of software testing, the scope of authority of the laboratory includes algorithms and software (standalone and embedded) MI and IIS used in air transport and in the aviation industry. The article describes the main tasks solved by the laboratory in the process of certification of the SYSTEM software.
