Abstract:
The workers’ health care is an extremely important objective by its direct contribution to the increase in the working capacity and it represents a first rank element in the continuous improve of the quality of life. The approach of well-being at the workplace, the strengthening of a risk prevention culture, the existence of an adequate social policy are the three characteristics of the EU strategy on health and safety field, established so as to protect the life, health and bodily integrity of the participants in the production process.In this respect, the study carried out on an EVA compound, conducted in order to estimate the lifetime of instrumentation and control cables used in nuclear power plants, is a must considering the special conditions of the existing environment. Thus, it is necessary to know the reaction of polymeric materials used in the electrical insulation of the conductors under the influence of anthropogenic and environmental factors at the workplaces.For this purpose, the EVA compound samples were subjected to an simple and combined (thermal and oxygen pressure) accelerated aging process. The evaluation of degradation degree was estimated by using the DSC method, and the obtained results were checked by measuring the elongation at break.The equipment used for the DSC (Differential Scanning Calorimetry) analysis is the DSC 204 F1 Phoenix-produced by NETZSCH GERATEBAU GmbH. The thermal aging was conducted in a special ovens system controlled by a LabView virtual instrumentation program.
