The article describes the results of a study of the effectiveness of the standards being implemented in railway transport. A general view of efficiency and standardization was analyzed. It was studied which document regulates the application of standardization in the Republic of Kazakhstan. Further, the international railway standard IRIS «International Railway Industry Standard» was taken as a basis, which, in turn, is based on the international standard ISO 9001. A study of the methods and types of effectiveness of standards was carried out, as well as an analysis of the applied international standard in the field of railway transport IRIS. The purpose of this standard is to create a business management system that allows for continual improvement, with an emphasis on preventing and reducing delivery defects. It is important to note that the effectiveness of standardization is evidenced by examples showing that ignoring standards turns out to be huge losses for a company for a number of reasons, for example, because its products have not been certified for compliance with a specific standard; due to the additional costs of the company for reworking products that are not manufactured in accordance with the requirements of the standards in the country of export. An analysis of the effectiveness of standardization work in the railway industry can be expressed in relative terms of the effects obtained as a result of the application of the standard: for example, in an increase in the level of safety or in economic growth. The basis for determining the actual effect is the actual level of production that existed at the given enterprise before the introduction of the standard. The measures that can be applied in order to increase the efficiency of solving the problems of developing standardization in the field of railway transport have been studied. Such standardization as one of the elements of technical regulation can provide a contribution to economic growth in excess of the corresponding indicators from the introduction of patents and licenses.
