FIELD: test equipment.
SUBSTANCE: product is placed into vacuum test chamber. Air is removed from the chamber and product volume. Preheated solvent is sprayed onto internal surfaces of the product to form laminar dripping film. Then pressure is raised by dry gas supply into the product volume, and solvent vapour flows evolving in the volume of vacuum test chamber are registered and measured.
EFFECT: enhanced efficiency, sensitivity and reliability of flaw detection.
