The aim of the invention is to create a method that is as accurate and reliable as possible for metrologically determining the end of a test interval (PI) which is to be maintained to perform a periodical test on pressure vessels (1) subject to load variations within operating cycles (AZ). Said aim is achieved by a method in which the maximum working pressure (p) actually reached inside the pressure vessel (1) per working cycle (AZ) is measured by means of a pressure sensor (2), a load variable (BG) is determined per working cycle (AZ) based on the working pressure (p) measured per working cycle (AZ), a resulting load value (BW) is determined for several successive working cycles (AZ) based on the respective load variables (BG) determined per working cycle (AZ), and the resulting load value (BW) is compared to a predefined comparative value (VG)). A signal indicating that the end of a test interval has been reached is output as soon as the resulting load value (BW) is equal to or greater than the predefined comparative value (VG).
