Opis:
In the paper, the concept of a model bench for accelerated ageing of bio-components and biofuels was presented. It is used to simulate the ageing process of biofuels and components of vegetable or animal origin, taking place during storage in the storage tanks. The construction of the bench’s essential elements and its equipment were designed and implemented in such a way as to mostly reflect actual storage conditions in large capacity tanks. An additional and unprecedented function of the bench includes the possibility to simulate the product transport conditions. Furthermore, a method of the test, with the use of simultaneously performed traditional tests on the physical and chemical properties monitored in the process of storage was presented. An analysis of the relation between values of the parameters obtained with different methods (on the model bench and under laboratory conditions) was conducted. In addition, their usefulness to assess the impact of logistic processes on the product quality was presented. In the paper, the results of the work executed within the framework of the project “Development of a prototype of the monitoring system the ageing rate and degree of bio-components and biofuels” within the Program Innovative Economy Operational Programme, Measure 1.4. “Support for goal-oriented projects” were used.

Opis:
Residual lifetimes and/or structural integrity assessments of critical components of mechanical plants and/or steel structures reąuire the knowledge of actual mechanical properties of the components' materials, because the material properties could be reduced throughout a service life by ageing. the use of standardised mechanical test techniques for determination of actual mechanical properties of the components under operation can cause its considerable damage due to size of necessary testing material and following repairs by welding. The need of a large amount of testing material can be eliminated by new advanced testing method based on „ non destructive " sampling of a small amount of testing material from the component surface. the mechanical characteristics are then determined by Small Punch) Tests (SPT). This paper describes the use of this advanced test technique for determination of tensile properties and fracture characteristics (FATT, J IC) of materials. The small punch test technique provides at present time a vehicle for determination of actual tensile and fracture properties necessary for optimisation of operating procedures and inspection intervals as well as for repairs strategies and residual lifetime assessment.
