Since the assigned value is a reference point when comparing the results of the participants of the qualification test. Frequently, qualification verification providers face a number of problems when choosing the assigned value. An incomplete analysis of the results of interlaboratory comparisons will lead to an inaccurate assessment of the competence of the laboratory, which contributes to the revocation of the certification of the accreditation of the laboratory participant. This article attempts to provide a complete statistical analysis of the results of interlaboratory comparisons from the beginning to the end of the tour with the content of all statistical analyses recommended in GOST ISO/IEC 17043-2013. The results of interlaboratory comparisons conducted in testing laboratories of Kazakhstan aimed at ensuring metrological traceability of pH measurements in a buffer solution are presented. The reference values of the buffer solution are determined in the state scientific metrological center.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.

It is important to implement a project without hitches. However, during the construction process, design flaws or environmental impacts can often arise in the end result. Therefore, proper design and monitoring allow taking preventive measures that helps to avoid overhaul of buildings in the future, which also affects to the cost of project, and sometimes-human casualties. During and after the construction of high-rise permanent structures often-unacceptable cracking can occur in the external walls and at the base slab of the basement. Respectively, groundwater starts to leak through the cracks of basement, compromising the serviceability and durability of the basement and rendering it unusable. The paper presents the use of fiber-optic sensor technologies geotechnical engineering. In this paper, it has been established the possibility of foundation monitoring system using fiber optic sensors during the construction process. The monitoring system includes a distributed fiber-optic voltage measurement system using a fiber-optic cable, which allows you to control deformations that occur on the surface of the plate. This study involves an investigation of the foundation system in a high-rise buildings and structures in Nur-Sultan city.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.

The paper presents current models of excavators operating on the territory of the Republic of Kazakhstan. The main technical characteristics of the machines are considered. Statistical analysis and processing in the software environment were carried out. Summary statistics for each of the selected data variables are provided. It includes measures of central tendency, measures of variability and measures of form. Based on the correlation matrix of indicators, it was revealed that the weight of the excavator has the greatest relationship with the digging depth, its capacity and bucket volume. Cluster analysis was carried out using the software package. As a result of cluster analysis, it was determined that the existing excavator designs can be divided into three groups. Histograms of the distribution are constructed. With their help, modal intervals and the middle are determined. The criterion of significance and the weighting coefficient for each indicator are determined. The coefficient of the technical level is calculated. Based on the results of the technical level, promising indicators of power values, digging depth, bucket volume and excavator weight are proposed.","PeriodicalId":168248,"journal":{"name":"BULLETIN of L.N.
