Proposal of conformity assessment and inspection procedure of a cyllinder flange
Ondruška, Jan ; Jankových, Róbert (referee) ; Harčarík, Matej (advisor)
This bachelor thesis contains the control plan creation procedure for conformity assessment of a cylinder flange. The thesis includes a selection from standards related to the above-mentioned problems and the drawing documentation of the part. The cylinder flange is analysed in terms of function and unambiguous specification of geometry on the drawing of the part with regard to further part inspection. Any deficiencies in clarity are dealt with in more detail and solutions to these problems are proposed. Control plans for inspection of the part directly in the manufacturing process and for inspection of the part during sampling were created using CAQ software and are attached to the work. The results of the work have been used to improve the process of manufacturing of the part.

Use of Surface Texture Parameters for Conformity Assessment and Process Control
Špačková, Magda ; Jankových, Róbert (referee) ; Harčarík, Matej (advisor)
This master‘s thesis deals with using surface texture parameters for conformity assessment and process control. The aim of the thesis was to create an overview of surface texture parameters, an overview of procedures for conformity assessment and process control using surface texture parameters, practical application on an industrial product and practical recommendations. The thesis includes an overview of profile and areal surface texture parameters, including an original translation of terms of the areal method. Methods of conformity assessment and process control in connection with the surface texture parameters are also described. Statistical analysis was performed based on 7200 values of surface parameters and 1843200 values of profile parameters which were measured on parts from serial production. The last chapter includes practical recommendations.

Accreditation audit in a testing laboratory according to ČSN EN ISO/IEC 17025: 2018
Kallerová, Barbora ; Maradová, Karla (referee) ; Šrámek, Jan (advisor)
This diploma thesis deals with the elaboration of a comprehensive internal audit proposal in testing laboratories for the needs of a Czech company engaged in the production of cleaning products. The aim of the work is to describe the current state in the selected testing laboratory in comparison with the standard ČSN EN ISO / IEC 17025: 2018, including complete documentation determining the scope of the testing laboratory. Subsequently, an internal audit was prepared and carried out, including the preparation of internal audit reports, evaluation and implementation of the conclusions of the testing laboratory. the resulting overview can serve testing laboratories as assistance in preparing for the accreditation audit according to the standard ČSN EN ISO / IEC 17025: 2018.

The Optimal Accuracy of Measurement Assurance in Accordance with Metrological Confirmation
Frank, Petr ; Kocman, Karel (referee) ; Nenadál, Jaroslav (referee) ; Hruška, Karel (advisor)
This thesis deals with the evaluation of accuracy of measurement and achieving the required accuracy level. This includes global analysis of the uncertainty evaluation, the calibration interval design and the creation of confirmation system. Basis of this work is in identification of all possible problems, which may occur during evaluation of accuracy and achieving the required accuracy level. The analysis is followed by suggested solutions for identified problems. It means namely the selection of probability distribution in case of uncertainty type A, evaluation of degrees of freedom in case of uncertainty type B, nonlinear correlation of input values, evaluation of coverage factor, the choice of method for calibration interval design and the procedure for meeting all metrological confirmation requirements. The last part of the thesis is practical measurement and result evaluation in the field of surge protection devices. This chapter demonstrates conclusions from the syntactical part.
