摘要: A method of testing the integrity a package seal (14) provided between container portion (11) and lid (12), includes steps of: initially reducing pressure acting on outer surface to cause bow inwardly position substantially maximum concavity while maintaining ullage volume within constant; further distend for increasing space; sensing change in distended wall.
