Popis:	This paper presents the results of interlaboratory testing the soil consistency - the Atterberg limits (liquid, plasticity and shrinkage limit). The tests were performed on representative samples of soil. The results were analyzed in two ways: numerical method - the Cochran test of precision and graphical interpretation - calculation of z value in accordance with the Standard ISO 5725-2 [1]. The followings were calculated: variance of repeatability Sr2, interlaboratory variance SL 2 and reproducibility variance SR 2.The samples were distributed by the method of divisibility to all participating laboratories.
