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.

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.

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.

Risk analysis in compatibility evaluation
Suchý, Marek ; Musil, Martin (referee) ; Koška, Petr (advisor)
This Master’s thesis deals with the new approach and global policies and their consequences on the process of conformity assessment. Furthermore, the modules those are used for this assessment and risk analysis, which is essential in this process. The practical part is focused on an analysis of risks to the submersible pump sets series U with electric motor TU-85.

Aspect of reliability in compatibility evaluation of products
Šenkýř, Michal ; Kovář, Miroslav (referee) ; Koška, Petr (advisor)
The diploma thesis deals with stating the aspects of reliability in product compatibility evaluation, namely with stating result uncertainty in product parameters testing and diagnosis which are imperative for introduction of the product to the market. The practical part of the thesis focuses on stating selected uncertainty in warm-water boilers testing, especially in gas fueled boilers with rated thermal input of max. 70 kW.

Legal Aspects and Practical Consequences of the Conformity Assessment - CE Conformity Marking
Cervanová, Iva ; Boháček, Martin (advisor) ; Vavrečka, Jan (referee)
The topic of my diploma thesis is removing the technical barriers of the trade of goods via harmonization of the essential requirements on the products -- mainly the legal aspects and practical consequences of the conformity assessment and the CE conformity marking. The goal of my thesis is firstly to find out what the main objective of the CE marking is and whether it really fulfills its role. Secondly, I want to find out how the process of conformity assessment looks like in practice. Thirdly I want to find out how the market surveillance is organized and how effective it is. My thesis is divided into six chapters. The first chapter depicts the situation as it had been before the marking was introducted. The second describes the statutory regulation of the CE marking system. The fourth chapter is dedicated to the process of the conformity assessment. The fifth chapter is about the market surveillance. The final sixth chapter explores problems that are related to the CE marking system.

Conformity assessment in commerce policy of EU countries
Kozlovská, Barbora ; Plášková, Alena (advisor) ; Skopal, Jaroslav (referee)
Difference between technical standards, legislation and certification and testing procedures in specific EU countries complicates unification of international markets. Therefore international standards and procedures for conformity assessment of products that are connected to Agreement on Technical Barriers to Trade have been created. Completion of all requirements, standards, procedures and marking, including proposals regarding resolving problematic areas, is the main content of this diploma thesis.
