Tiivistelmä
The aim of this thesis study was to get all the useful information from the BGD 897/408B environmental testing chamber by doing different tests. Processing and analysing of the test results was done by comparing test results to IEC 60068-3-30 and MIL-STD 810 standards and, also, to specifications of the manufacturer. This way, solid conclusions for the operation of the testing chamber could be made.
Basic information regarding environmental testing was gathered from many regulations, standards, and materials released by different manufacturers of environmental testing equipment. Also, information of temperature and humidity as physical quantities was gathered.
By finding out quantities that needed to be verified, environmental tests were designed. The main areas concerned in the tests were the static and dynamic accuracy of temperature and RH control, interaction of these two quantities, and capabilities of the testing chamber.
In the future, the information gained from this study can be used to optimize test cycles to be as fast as possible, all the errors in the working principle of the chamber can be taken into account and only important results can be gathered from tests. By optimizing the environmental test, no time need to be wasted by doing irrelevant tests and lengths of the test periods can be designed to be appropriate.
