    The paper is focused on summarisation of the knowledge obtained with the tensile test of ceramics foams of different samples geometry, interpretation of data obtained and possible consequences relating to foam material mechanical behaviour. Material used in the investigation was alumina based foam. Special fixture and testing rig was developed to assure transfer of the load to the ceramic foam specimen. The specimen size (in the range of dimensions applied in this investigation) does not affect substantially the average values of tensile strength as it has been shown based on the Weibull statistical analysis. From the data sets for the specimen sizes applied and for both cell sizes, having 10 and 60 PPI, it is obvious that there are no substantial differences in the quality of data obtained from smaller and larger specimens.
