The article presents basic concepts related to accredited calibration laboratories in accordance with ISO/IEC 17025. It describes in detail one of the only few existing in Poland calibration laboratories which deals with instruments for sound measurements. This laboratory is an interesting case as it is the only one in Poland, located in a company developing new instruments, producing, selling them and conducting their service in all over the world. Thanks to this location, the laboratory is able to provide their services not only in Poland but also abroad, which could affect revenues. In the paper laboratory equipment is presented and the innovative ways to increase measurement throughput is discussed. The calibration and measurement capability developed on the basis of uncertainty budgets is given. The activities carried out during the calibration are presented as well as the contents of the first page of the certificate. In the conclusions the strengths of the laboratory are listed.
