摘要： A method of testing the seal of transportable containers, such as suitcases, trunks, and cases, which form inside them, in at least one closed configuration, at least one compartment to be seal tested, the method includes the following steps: accommodating a container to be tested, in the closed configuration, in a saturation chamber; dispensing a tracer gas in the saturation chamber; and lowering the pressure value inside the compartment. The method further includes waiting for a preset time, keeping the saturation chamber closed; drawing an air sample from the compartment; and measuring the actual concentration of tracer gas in the air sample drawn from the compartment. Thus, an actual concentration higher than a reference value, correlated to the normal concentration of tracer gas in the atmosphere, can indicate the entry of the tracer gas in the compartment and a condition of at least potential defectiveness of the seal of the compartment of the container.
