Rotational seismology is a relatively new area of geoscience, which was formed in the past 20 years. During this time, new instruments were created; interesting data was obtained and verified; and main directions for further development of rotational seismology were identified. Now a much greater number of observations are required for further development of rotational seismology. We need to create networks for recording of rotational movements, which should be taken parallel to the traditional seismometrical measurements. This requires development of appropriate metrological standards. It is necessary in order for the seismological data to be useful. More detailed views on this issue are presented in this work.
