According to "STANDARTINFORM", the most popular recently was GOST ISO/IEC 17025-2019, General requirements for the competence of testing and calibration laboratories. In May, consumers were more interested in the national standards for gas distribution systems: GOST R 53865-2019, Gas distribution systems. Terms and definitions, and GOST R 58778-2019, Gas distribution systems. Distribution networks and consumers gas network. Gas pipelines of high-pressure category 1a. Both standards came into force on May 1, 2020.
GOST R 53865-2019, introduced to replace the standard of the same name in 2010, establishes the terms and definitions in the field of gas distribution systems, which are recommended for use in all types of documentation and literature in the field of gas distribution systems, included in the scope of work on standardization and / or organizations using the results of these works.
GOST R 58778-2019, introduced for the first time, covers design, reconstruction, construction and operation (including conservation and liquidation) of high-pressure gas pipelines of category 1a of gas distribution networks and gas consumption networks transporting natural gas through gas turbine and combined cycle plants. According to the standard text, high-pressure gas pipelines of category 1a are classified as facilities with increased responsibility. Laying of gas pipelines of gas distribution and gas consumption networks is not allowed in populated areas, except those that are legally classified as production zones; through the body of the embankment of the earth bed of the railway and highway; in tunnels, on bridges and under bridges of railroads and highways; together with electric cables, pipelines for other purposes and communication cables.
GOST R 8.741-2019, State system for ensuring the uniformity of measurements. Volume of natural gas. The general requirements to procedure of measurements, was popular in May. The document came into force last year to replace the standard of the same name in 2011. This standard applies to methods of measuring the volume of natural gas corresponding to a regional, national, interstate standard or, in the absence of these standards, - the standard of the organization. The document is applied in the development and application of methods for measuring the volume of gas reduced to standard conditions, in production, processing, transportation, storage, distribution and consumption of gas.
GOST R 50.05.07-2018, Conformity assessment system for the use of nuclear energy. Conformity assessment in the form of examination. Unified procedures. Radiographic examination, introduced for the first time in 2018. This document specifies the requirements for non-destructive testing by radiographic method using X-ray, rigid brake, gamma radiation and fixing the transformed radiation image of the object of control on radiographic film. Besides, the standard specifies the requirements to control means, personnel, processing and registration of control results, metrological support and safety.
