3 Reference Regulatory Technical Documents

Certification of test equipment is carried out on the basis of the Law of the Russian Federation "On Ensuring Unity of Measurements" and is regulated by the requirements of GOS 8.568. Certification of test equipment. Basic provisions ", as well as current norms and rules of metrological support.

In accordance with the requirements of GOST 8.568, only means of measuring the approved type must be applied in the certification of test equipment, which have passed the relevant government tests according to PR 50.2.009 - 94. If the certificate test equipment is intended for testing objects entering the scope of the law of the Russian Federation "On ensuring the unity of measurements ", They must be believed to 50.2.006 - 94. If certified equipment is intended for testing for safety and defense, measurements that have passed government tests and approved in accordance with GOST RV 8,560 should be applied. In all other cases, the measurement tools used for certification of test equipment must be calibrated, as required by the Law of the Russian Federation "On Ensuring Unity of Measurements".

The measurement measurement methods used in certification must be standardized or certified according to GOST 8.563. It is allowed to use not certified techniques only if the parameters of the accuracy of the results obtained are not known in advance.

In accordance with the requirements of GOST 8.568, any test equipment is subject to certification.

In the text of the specified GOST, the terms and definitions are not given, but references to GOST 16504 "SGIP. Testing and quality control of products. Basic terms and definitions. " This regulatory document establishes the terms used in science, technology and production terms and determining the basic concepts in the field of testing and product quality control.

Terms set by this standard are required for use in the documentation of all types of scientific and technical, educational and reference literature.

For each concept there is one standardized term. The use of the synonyms of the standardized term is prohibited.

The terms marked with an asterisk (*) are approximate equivalents. Consider the main of them.

Tests * - experimental determination of quantitative and (or) qualitative characteristics of the properties of the object of tests as the result of the impact on it, when it is functioning, when modeling an object and (or) impacts.

The most important sign of any test is the adoption based on their results of certain decisions. Another sign of the test is the task of certain test conditions (real or modeled), under which the set of impacts on the object and the functioning modes of the object is understood.

Determining the characteristics of an object during tests can be carried out both in the functioning of the object and in the absence of operation, if there is impacts, before or after their application.

Test conditions are a set of actuating factors and (or) modes of functioning of an object during testing.

Test conditions include external affecting factors, both natural and artificially created, as well as internal exposures caused by the functioning of the object (for example, heating caused by friction or electric current), and the functioning modes of the object, methods and place of its installation, installation, fastenings, speed of movement, etc.

Normal test conditions * - Test conditions established by regulatory and technical documentation for this type of product.

Test object * - Products subjected to tests. The main sign of the test object is that, according to the results of its tests, this or other decision is made on this object: about its shelf life or marriage, the possibility of presenting the following tests, the possibilities of serial release, etc.

Test method - rules for applying certain principles and test facilities.

Test Program * - Organizational and methodological document, mandatory for implementation, establishing an object and objective objectives, types, sequences and volume of experiments, procedure, conditions, place and timing of testing, ensuring and reporting on them, as well as responsibility for ensuring and conducting Tests.

Test Methods * - An organizational and methodological document, mandatory for implementation, including the test method, means and testing conditions, sampling, algorithms for performing operations to determine one or more interconnected characteristics of the object properties, forms of data representation and estimating accuracy, accuracy of the results, Requirements for safety and environmental safety.

Test media * - technical device (substance) and (or) material for testing.

The concept of tests is covered by any technical means used in testing. This includes, first of all, the test equipment under which means of reproducing test conditions. Tests include measuring instruments, both built into test equipment and applied in tests for measurements of certain characteristics of the object or control of the test conditions. Test tools should also include auxiliary technical devices for fastening the test object, registration and processing of results.

Testing equipment - Test tool, which is a technical device for playing test conditions. Since the term "test equipment" as a means of testing means for reproducing test conditions fully covers all interpretations of the concept of "test stand", then, accordingly, the test stand is test equipment.

Certification of test equipment - determination of the normalized accuracy characteristics of test equipment. Their compliance with the requirements of the regulatory and technical documentation and the establishment of the suitability of this equipment to operate.

The accuracy of test results is the test property characterized by the proximity of the test results to the actual values \u200b\u200bof the characteristics of the object, under certain test conditions.

Test Protocol - a document containing the necessary information about the object of tests used by methods, means and conditions of testing, test results, as well as conclusion according to the test results, decorated in the prescribed manner.

Test division - a division of an organization to which the leadership of the latter entrusted to conduct tests for their needs.

In accordance with GOST 8.568, under the main purpose of certification of test equipment is to confirm the ability to reproduce the test conditions within allowable deviations and the establishment of the use of test equipment in accordance with its purpose.

This suggests that in the process of certification (especially primary) it is necessary to determine the ranges recreated by test equipment (test modes, loads, etc.) and the actual values \u200b\u200bof the errors of their task in accordance with the purpose of this test equipment and the specified test conditions.

One of the features of GOST 8.568 is that it requires primary certification when entering test equipment into operation in this test unit, regardless of whether it was certified earlier. Testing equipment, which has previously passed primary certification, is subjected to periodic certification during operation. In the case of repair, modernization, work with the foundation or any other works that can influence the technical characteristics of the test equipment, it is subjected to re-certification. This GaTe emphasizes that for certification of test equipment used for the purposes of mandatory product certification, when testing products for compliance with the mandatory requirements of state standards and in the production of products supplied under contracts for state needs, measuring instruments of approved types should be applied in accordance with 50.2.009, which should be believed, measurement methods must be certified in accordance with the requirements of GOST 8.563.

In the event that the testing equipment is intended for testing products on orders of the Ministry of Defense of the Russian Federation, the measurement funds used must be subjected to tests and approval of the type in accordance with GOST RV 8.560.

It should be borne in mind that the previously used term "accuracy characteristics" of test equipment installed in GOST 16504, in GOST 8.568 does not apply: it is replaced by the term "technical characteristics" of test equipment, although it is indicated that they must be within the established limits, t. e. The error values \u200b\u200bof these characteristics must be set.

Primary certification of test equipment

The primary certification of the test equipment is to examine the operational and project documentation (if there is the last), on the basis of which the installation of test equipment was made, experimentally determining its technical characteristics and confirmation of the use of this equipment in accordance with its intended purpose. Primary certification is carried out in accordance with the current regulatory documents on the methods of certification of a certain type of test equipment and (or) according to programs and methods of certification of specific equipment. The program and technique (one document is allowed - PM program - PM) primary test equipment certification is developed by the organization (enterprise) conducted by this certification. Since the primary certification facilities are a specific test equipment with a certain list of normalized technical characteristics, then from this list it is necessary to reasonably select the characteristics to be defined or control. At the same time, it is necessary to pay special attention to those specifications that are not measured (not controlled) during testing.

For example, if an electrical pulse generator is used as test equipment, then it is necessary to determine the form of a given pulse, the nonlinear distortion coefficient, the range of amplitude and frequency of the output signal, since the frequency and amplitude value is measured by the built-in measurement tools. These tools make it possible to measure the characteristics of the output signal, but they cannot provide information about that. What accuracy can be set a signal, i.e. Do not determine the possibilities of testing equipment according to the accuracy characteristics of the installed mode. Thus, during certification of this test equipment, it is necessary to determine the actual values \u200b\u200bof the frequency and amplitude ranges, the form of the signal task, the error of the task of the frequency and amplitude values, the stability of the output signal. Naturally, the built-in measuring instruments must be believed and have the current corresponding marks about this verification (calibration).

The primary certification of test equipment is conducted by the Commission appointed by the head of the organization (enterprise) to which the certified equipment belongs. The Commission includes representatives:

Divisions of the enterprise (organization) conducting tests using this test equipment;

Metrological service of the enterprise (organization), the division of which conducts tests;

State Scientific Metrological Centers and (or) bodies of the State Metrological Service when using test equipment intended for product testing for its mandatory certification or for compliance with the mandatory requirements of state standards in the production of products supplied under contracts for state needs.
