The theoretical part of the thesis focuses on understanding the term standardization which is necessary for comprehending the thesis itself as well as the workings of the institution like SIQ. Testing a variety of products is subjected to procedures of standards or better said, testing according to the guidelines of standards. For this reason, the development of standards is also described, as well as the three standards that were used for the testing of the vending machine. Since the thesis relates to the non- conformities of the vending machine, the term non-conformity is also described, by which we can define the deviations of the results required in the standard. Non-conformities arise in the process of development, testing, and also often in the use of the product when it is already in the clients' hands. It is therefore crucial that a place and a cause of a non-conformity are found and that this is corrected by an appropriate corrective action.
The main part of the thesis presents the tests of the compliance of the vending machine, with the presented measuring instruments used, which helped to obtain the results that helped finding the non-conformities in the process of testing. In order to obtain the results, we had to familiarize ourselves with later described standards in which the permissible limits for evaluating the results are described, that is, whether the machine successfully passed the test or not. The discovered non-conformities are described with corresponding graphs and images, and so is their removal procedure. The most critical that stand out are: the non-conformity of the overflow of the vending machine, the non-conformity of overloading the toroidal transformer and the insufficient protection against accessible moving parts.
The conclusion summarizes the topic of the thesis, which describes the main results of found non-conformities of the vending machine and the main conclusions that come from the results.
