    • A method for testing waterproof property of an object designed to prevent water from penetrating into the inside of the object and having a hole, the hole allowing air communication between the inside and the outside of the object, the method includes: attaching closely to the object a tank having an opening hermetically surrounding the hole to form an air communication path between the inside of the object and the tank to form a single air tight space; placing the object to which the tank is attached in an air tight container; either or both of injecting gas into and extracting the air from the air tight container containing the object so as to change the gaseous pressure of the air tight container; and measuring an internal gaseous pressure of the air tight container to determine whether the waterproof property of the object is effective or not.
    • 一种用于测试设计用于防止水渗透到物体内部并具有孔的物体的防水性的方法,所述孔允许物体的内部和外部之间的空气连通,所述方法包括:紧密地附接到物体 具有密封件围绕所述孔的开口以在所述物体的内部和所述罐之间形成空气连通路径以形成单个气密空间的罐; 将容器附接到的物体放置在气密容器中; 从容纳物体的气密容器中注入气体并从中抽取空气,以改变气密容器的气体压力; 并测量气密容器的内部气体压力,以确定物体的防水性能是否有效。
