FIELD: testing technology. SUBSTANCE: sensors are placed in the module under test, after which module is mounted on the flange by means of fasteners. Then housing is mounted. Stand is filled with water and test is conducted by applying the external pressure. Fitting the sensors on the inner surface of the module reduces labour consumption at simultaneously testing the module for tightness and measuring the motion of loadbearing wall of the module and cover of the housing. EFFECT: enhanced reliability. 3 dwg
