FIELD: testing equipment.
SUBSTANCE: tank is mounted in testing chamber, which is drained until at least pressure of steam of liquid component. Pressure in surrounding space is controlled and in test chamber respectively as well. Leak is detected by controlling pressure change in space surrounding tank, which occurs because of liquid evaporation, liquid coming from leak location and evaporated in surrounding space with low pressure.
EFFECT: higher precision and lower costs.
