[en] The efficiency of the composite repair system is usually evaluated through semi-destructive test: pull-off test. But some difficulties can also be induced by the eccentricity of the load application, due to incorrect placement of the test device. The paper presents the results of a research project and the impact of incorrect design on tensile strength values. According to results of laboratory experiments and modelling, it can be observed that, if there is an influence of 2o and 4o angle of inclination on pull-off bond strength, it is however not statistically significant: the decrease of pull-off strength is usually no larger than 8% for 2o
