Specification of concrete strength according to ČSN EN 13791 (2020)
New standard ČSN EN 13791 (2020) provides the procedures for estimating characteristic strength of in-situ concrete using cores specimens. The submitted contribution reviews the testing of outlying observations and compares the estimation in accordance with ČSN EN 13791 and ČSN EN 1990. It is shown that the approaches in ČSN EN 13791 are only partly based on the principles of mathematical statistics and it is recommended to harmonise fully the estimation with the procedures in ČSN EN 19
