At one of Polish steelworks there was carried out an experiment, which aim was measure-ment of voltage fluctuation parameters at the same point of supply network, by means of different measuring instruments, than on that basis assessment of credibility of ten selected flickermeters, available on the Polish market. AU instruments were dedared by the manufacturers as complying with the terms of the IEC 61000-4-15 standard Their indications however, differ significantly as the cxperi-ment has demonstrated. The authors do not assess the correctness of indications of specific instruments, rather conclude their substandal discrepancy. Obtained results indicate that the recommendations of IEC 61000-4-15 standard allow for construction of correct, i.e. complying with the standard, instruments which do not meet their primary metrological objective (comparison of measuremcnt results). Normally a uscr of the instrument cannot evaluate hunself the correctness of measurements while manufacturer's declara-tion does not guarantee their correctness, as the experiment has demonstrated.
