Determination of thermal properties of gloves by means of thermal manikin
Pidrová, Kateřina ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on determination of thermal properties of gloves by means of thermal manikin. The background research with relation to this topic together with derivation of the computational equations used for the following measurement are presented in the first part. The most significant part of this work is suggestion of procedure for measuring the heat resistance of gloves with thermal manikin based on procedure from ČSN EN 511. This methodics was verificated with 5 pairs of gloves together with analysing the uncertainties and testing the repeatability of this measurement. This work also contains the outline for all of the measured pairs with posibilities of their usage in specific situations and surrounding air temperatures. At the end of this work is mentioned brief summary of achieved results.

Measurement of clothing sets by means of thermal manikin
Hanzlík, Martin ; Toma, Róbert (referee) ; Fišer, Jan (advisor)
This diploma thesis is focused on the experimental determination of thermal resistance of the gloves and their combination in the layering system. The measurement was based on procedure specified in the standard ČSN EN 511 by means of thermal manikin. The thesis begins with the description of heat transfer mechanisms, description of glove materials and measurement methodology. The body of paper consists of the measured data analysis and equation design for determination of the glove layering system thermal resistance. At the end of the thesis, these equations are evaluated and it has been shown, that the thermal resistance of glove layering system cannot be precisely determined by the calculation, and it is necessary to measure the whole three-layer system.
