"For the correct examination of the sheet metals formability the precise measurement of plastic strain ratio is necessary. Plastic strain ratio is necessary as an input value for computer simulation of drawing process. The measuring of all input values which we need for the ratio calculation is burdened by error. The paper is engaged in means of appreciation of reliability of mesurement results from this point of view. Next it allows the sight in confrontation of two means of measurement ? the first one is based on \u010CSN ISO 10113, the second one on determination of the plastic strain ratio using these values: the sheet-metal thickness and width, both measured in points which are distant from places of deformation after the rupture of the sample. There is tested the method of the alternated measuring by the help of statistical methods."@en .
