FIELD: testing engineering.
SUBSTANCE: method comprises filling the receiver with gas and blowing the passages of the article with the gas from the receiver through a pipeline. The receiver is filled with gas up to the pressure required for generating the critical pressure drop between the receiver and ambient fluid. The temperature of the gas in the receiver as well as the pressure at the initial moment of blowing and at the end moment of blowing are measured, and thus the rate of pressure change is determined.
EFFECT: enhanced precision.
