Description	A sensitive determination of mechanical properties of brittle building materials of existing structures, requires gathering of samples (stones, bricks and concrette) by core drilling. Due to the fact, that the material samples may change their properties (for example, due to changes in humidity) during transportion, it is preferred to test samples in situ. Brittle materials are known for a high dispersion of measured parameters, especially in tension, due to present defects. This situation is usually overcome by large set of specimens and statistical evaluation, but this is not a case for precious materials from historical objects. Therefore method requiring less, ideally only one specimen is preferable. Development of portable machine for Split test was therefore the best choice. Split test is based on the Brazilian test, in which a disc specimen is compressed with diametrically opposite and symmetric line loads.
